YG Acoustic Sonja 3.2 Speaker: The Upgrades – by Moreno Mitchell

How great became greater

Caveat: This review is mainly targeted at present YG Acoustic Hailey and Sonja owners

Getting Started

My journey with the YG Acoustic experience takes me back 18 years, to the 2008 Rocky Mountain Audio Fest (RMAF) in Denver, CO. This was my very first visit to the highly attended audio show as a Stereo Times reviewer.  I met Clement Perry, Bill Wells, and other journalists for the first time at the well-attended event. Aside from being in awe of everything that was going on during the show, I tagged along with Clement for the first part, visiting numerous rooms, watching him tote this enormous camera, and taking pictures of just about everything in the building (LOL). I was having the time of my life; it was a new experience for me, and I loved it. Sometime during the second day, I teamed up with Bill Wells, and he suggested we visit one of the larger lower-level ballrooms where the YG Acoustics were exhibiting. Needless to say, my fascination and journey with the YG Acoustics speakers began right then and there.

When Bill and I entered the overly crowded ballroom of significant size, I could have sworn I was in the New York Symphony Hall. The sounds coming from that room were utterly captivating. I asked Bill to explain to me how in the world a sound can be so real and alive coming from electronics. Bill’s response was “directed towards the YG Acoustics loudspeakers”. Bill had reviewed a pair of their YG Acoustic Anat speakers, so he knew from experience what the top models were capable of.  My goal was to own a pair of these magnificent speakers someday; however, they were priced well beyond my audio budget at the time.

I spent the next few years trying to find a set of speakers that could remotely capture what I had heard at the 2008 RMAF show. After purchasing numerous brands over the years, I failed at capturing what I heard at the show. After attending many shows since 2008, I made it my business to visit YG Acoustics’ exhibits no matter what. Finally, in 2022, my break came, and I was able to purchase a pair of YG Acoustic Hailey 2.2 speakers. From that point on, all my previous speaker purchases became distant memories. After a year, I upgraded my electronics from solid-state to tubes, and I thought I was set for life. However, we audiophiles never know how to leave well enough alone. At the 2023 Axpona Audio show, the following year, I heard the YG Acoustic Sonja 2.2i speakers, and my audio soul was jolted. Not to say the Haileys weren’t doing it for me; however, if I could swing a pair of the Sonja, I was going to go for it.

Nothing from nothing leaves nothing, as the saying goes. I was able to procure the Sonja 2.2i speakers the very next year. From the start, I was nervous about whether Sonja’s would be overkill in my medium-sized room. The Haileys were almost the perfect fit; however, I wanted more solid mid-range, and the Sonjas delivered. My journey was over, or so I thought. In 2023, YG Acoustics announced the Sonja 3.2 model. My thoughts at the time: “I’m Good. “I absolutely loved what the Sonja 2.2i was delivering in my listening room. I felt a match with the Thrax Spartacus tube amps and the Libra tube preamp; once again, my journey was fulfilled. I later added another pair of Thrax 350-watt Teres amplifiers for bi-amping the Sonjas. The sonic improvements were astounding: more headroom, tighter bass, faster transients, etc.  

This thought concept lasted until I attended the 2024 Capital Audio Fest in D.C. Once again, I teamed up with Bill Wells, and we had a blast visiting numerous outstanding audio exhibits. However, when we stepped into the YG Acoustic room, I heard a sound so open and alive coming from a pair of speakers I once owned.

The YG Acoustic Haileys were on display. Bill and I looked at each other. They did not sound like the Haileys I owned 2 years ago. These Haileys sounded like they were on steroids.  Introducing myself to the YG sales rep, Duncan Taylor, and I asked, “What the heck did you guys do to the Haileys? They sound better than my Sonja 2.2i at home.” He began to explain in detail all the upgrades that went into the new Hailey 3.2 models. He also informed me that the Sonjas had been upgraded to version 3.2. When I returned home, I began researching information about the YG Acoustics Sonja 3.2 loudspeakers.

Decision to upgrade to level 1, Lattice Tweeter

This review will focus on what it took for me to upgrade my existing $99k Sonja 2.2i speakers to the latest Sonja 3.2 model and the results of the upgrade. I contacted YG to obtain information regarding available upgrades for my Sonja 2.2i. The following information was sent to me.

Reference Upgrade Program Supporting Upgrades

An investment in a YG Acoustics loudspeaker is the beginning of a long-term relationship. Our culture of continuous improvement means our R&D teams in Colorado and Cambridge are constantly pushing the boundaries of what is possible in audio reproduction. The fruits of this relentless innovation should be shared not only with new customers but also with our existing family of owners. The YG Upgrade Program is the tangible expression of this commitment, ensuring the speaker you invested in continues to deliver state-of-the-art performance for years to come.

Our upgrade paths are not about minor tweaks; they represent fundamental leaps in performance driven by genuine technological breakthroughs. Discoveries such as our revolutionary Lattice tweeter, the precision-machined Stellar waveguide, and our advanced new crossover topologies have redefined key aspects of loudspeaker design. The Upgrade Program is the mechanism through which we make these proven, next-generation technologies available to earlier models, allowing them to benefit from the very same engineering that defines our latest creations.

To ensure the full potential of these new technologies is realized, our most comprehensive upgrades are performed meticulously at a YG facility. Each speaker is returned to the technicians who built it, where it is carefully disassembled and fitted with new components. Afterwards, the speaker is thoroughly cleaned and, most critically, undergoes the same rigorous, multi-domain testing and measurement protocols as a brand-new loudspeaker. This factory-level process provides absolute assurance that your upgraded speaker will perform to the highest possible standard upon its return.  

 

Available upgrades offered are as follows:

Level 1: Lattice Tweeter

Level 2: Lattice Tweeter and Crossover

Level 3: Full Upgrade

Binding Post Upgrade

In this review, I will provide background information on levels 1, 2, and 3. For my model, I initially chose level 1 and, after 6 months, opted for level 3. Initially, upgrading the existing BilletDome tweeters in the YG Acoustic Sonja 2.2i to their new lattice tweeter would be sufficient. After reading about the lattice tweeter upgrade (see below), I was all in.

“The Level 1 upgrade is the replacement of the old tweeter in the Reference loudspeaker with a new Lattice tweeter, but without any further changes. In 2016, YG introduced its revolutionary BilletDome tweeter: a soft-dome tweeter supported by a stiff, lightweight aluminum airframe machined in-house from aluminum billet.

This provided exceptional Reference Upgrade Options performance, combining the high-frequency extension of a beryllium dome with the realism and smoothness of a fabric dome.

YG’s new Lattice tweeter builds on this, substantially improving on the industry-leading performance of the BilletDome.

The new Lattice airframe is machined in-house from a specially selected aluminum alloy that combines extreme lightness with an exceptionally high impulse transmission speed. Starting from an 80g billet of this special alloy, carefully heat-treated before machining, we produce a final Lattice airframe weighing less than 0.03g (0.001oz), finished to a precision finer than 0.001mm. This airframe is attached to the fabric dome and the voice coil.

The Lattice airframe shape is the result of millions of CPU hours of computational optimization. It damps the break-up modes of the fabric and also transmits voice-coil impulses into the overall structure much more efficiently.

 In measurement, it improves impulse response, extends the frequency response, and reduces distortion. The shape of the Lattice widens the tweeter’s angular emission pattern at high frequencies, providing a huge sweet spot.

More importantly, listening increases detail retrieval, realism, and imaging, all while remaining un-fatiguing.

Upgrade Process

An experienced dealer with technical knowledge can carry out the Level 1 upgrade, and there is no need to send the speakers to a YG facility. However, they can still be returned to YG for complete testing as part of the upgrade process.

Upgrade Compatibility

Almost all historical YG speakers can benefit from the Level 1 upgrade. However, we will need the model and serial number of your speaker to verify.”

Lattice Tweeter Installation

At the start of January 2025, I scheduled the level 1 Lattice Tweeter upgrade. It was arranged for Duncan Taylor to visit my home for the upgrade. This was a viable option for upgrading at home; it was huge because there was no need to transport the speaker. Duncan flew into my city to personally perform the tweeter change. Anytime any work is done on any component of my system, I become extremely nervous. Duncan, however, was all business and surgical in his approach and methods with the tweeter change. In all, it took less than 2.5 hours to accomplish the tweeter change. He brought all the tools, screws, and seals needed for the upgrade. It was a flawless operation.

Level 1 Lattice Tweeter Impressions

With the addition of the Lattice Tweeter, one of the main improvements noticed was the widening of the listener’s sweet spot. Typically, and depending on the source being played,  the span of control was limited to shoulder width. What I mean by span of control is how far to the left or right I leaned while in the listening chair. With the Lattice Tweeter installed, I noticed that the span of control has been more unlimited. I guesstimate it to be a 50% increase. Although I felt the addition of the Lattice Tweeter to be significant, I still did not hear what I heard from the Hailey 3.2 at the 2024 Cap Audio Fest. I needed to validate, so I scheduled another session to listen to the YG Acoustic Sonja, which was exhibited at the 2025 Southwest Audio Show in Dallas, Texas.  At the show, I visited both YG Hailey 3.2 and Sonja 3.3 speaker exhibits. The sonics were very musical and captivating; this was more like what I had heard at the 2024 Capital Audio Fest, despite the rooms not being ideal for audio listening.

Change of Direction

Although upgrading my Sonja 2.2i speakers with the Lattice Tweeter was a definite improvement, I felt like there was still ‘something’ more I was after. That ‘something’ was what I heard from the Hailey and Sonja version 3 at both audio shows. The main reason I fell in love with the YG Acoustic sound is that it has a presentation unlike any other speaker I’ve ever listened to. Sonja literally connects; they’re not a piece of equipment but an interaction with my inner being. The YGs allow me to absorb the music; they give me goose bumps whenever I listen to a well-recorded track. It’s how they draw me closer to the heart and soul of a musical experience.  This experience is what I set out to capture in my listening room, especially after a trying and stressful day. The Sonja 2.2i always performed flawlessly; however, when I heard the version 3, I knew there was another level of improvement possible, and with the addition of the Lattice Tweeter, it was evident that I had only traveled part of the way.

Decision Time

To make a long story short, I had to choose between upgrading to Level 2 (crossover upgrade) or Level 3 (complete upgrade to version 3.2). After thinking about having to ship those heavy beasts to the factory, I decided to go all the way with upgrading to Level 3.

 

 

Comprehensive differences between Level 2 and Level 3

Level 2: Lattice Tweeter and Crossover

Background

The Level 2 upgrade replaces the old tweeter in the Reference loudspeaker with a new Lattice tweeter and upgrades to version 3 of the crossover, without changing any cabinet panels.

Hand in hand with the Lattice tweeter, the version 3 crossover designs are one of the most significant steps forward in Reference 3. Benefitting from our iterative cycle of listening, measuring, and modeling, the circuits and components are truly innovative, with topologies and approaches that deliver performance previously considered impossible for dynamic loudspeakers.

Reference Upgrade Options

With the “Dual Coherent 2” crossovers in Reference 2, YG was already at the forefront of the industry by making the two drivers exactly in phase at the crossover frequency. Another way of saying this is that the two drivers are “phase coherent” at that point. To achieve this, in-house software optimized both the frequency response and the relative phase.

The ultra-coherent crossovers in Reference 3 take that performance to a whole new level. By optimizing the amplitude, phase, and phase slope, the drive units are phase-coherent over a wide range—several octaves on either side of the crossover point. This means that, over the entire range where each driver produces meaningful output, it is moving in exact synchronization with its neighboring drive unit. To your ear, it seems like there is just a single source of sound.

Beyond this, there are particular characteristics of the phase slope that make a speaker more convincing to the human ear. Not only do we closely align the phase of the two drivers over a wide frequency range, but the shape of the phase slope across that full range meets the ideal requirements of human hearing.

The effects? In measurements: vanishingly low distortion across the crossover frequency range, excellent transient response, superb linearity. All of this is delivered evenly throughout a huge listening volume. By acting as coherent sources, the drive units approach the ideal “point source” of acoustic energy, minimizing room-related issues and ensuring a uniform listening experience throughout the room. When listening: effortless realism, holographic imaging, exceptional pace and timing, and most importantly, a complete lack of fatigue. The impact is just as noticeable at high volumes as when listening quietly, with breathtaking moments of musical intimacy as the tiniest sounds are reproduced perfectly. Just as importantly, all this is delivered throughout a huge listening area, not just a tiny sweet spot.

Unusually in a crossover design, we have paid as much attention to the phase in the bass. There is exceptional phase alignment across the midrange and bass around the crossover point, spanning multiple octaves. The same low distortion and transient response can be heard in the bass of almost every musical genre—tight, full, realistic bass with a slam and impact that you can feel. Again, at high volume levels, there is incredible scale. Still, the benefits are clearly audible in the softest passages, where hall acoustics and spatial cues—which often span the frequency range between bass and midrange—are perfectly reproduced. To our knowledge, the scope and depth of measurement and modeling in Reference 3 are unparalleled in our industry. We understand every aspect of the cabinet and drive units; we model the crossover not at the circuit level but using a physics model that examines the internal structure of each crossover component (modeling the Page 3 Reference Upgrade Options), electron flows, and magnetic fields. Together, these have allowed us to design every aspect of the loudspeaker to work together perfectly.

To deliver the performance of Reference 3, we have had to design our own crossover components to deliver exactly the behavior we need. The circuit designs differ significantly from traditional crossovers based on standard frequency filter elements. The layout of each component is precisely optimized on the board, while the PCB material, copper tracks, and even the internal wiring are to our exact specifications. Reference 3 is an exercise in perfection.

One benefit of computational modeling is that we were also able to measure and model many different amplifiers—from multi-kilowatt solid-state monoblocs to single-ended triodes that deliver just a handful of watts. These detailed amplifier models played an essential role in the crossover design. Every Reference 3 model is designed to work with as many amplifiers as possible and deliver the very best sound with each one. Yes, as a dynamic loudspeaker with a sealed cabinet, there will be a limit to the sensitivity we can achieve, even with the latest rare-earth magnets to optimize efficiency. Indeed, we have designed our crossovers to minimize energy loss in the electrical network, delivering the highest possible efficiency for the drivers and cabinets. However, the design ensures excellent sound quality throughout the available volume range.

Upgrade Process. While our most experienced dealers and distributors can perform the Level 2 upgrade, we recommend that the speakers be returned to a YG facility for complete testing as part of the upgrade process.

Upgrade Compatibility

 While the Level 2 upgrade is available for many of our past models, there are a few cases with very early versions where there is a physical conflict with the cabinet design. In these cases, we may have special solutions to propose. We need the model and serial number of your speaker to verify that this upgrade is possible and to prepare the wiring for optimal operation with your loudspeaker. Over time, the internal wiring and connections of our speakers have evolved, and we will build the upgrade to match your speakers’ configuration.

 

Level 3 Full Upgrade

The Level 3 upgrade replaces the old tweeter in the Reference loudspeaker with a new Lattice tweeter, upgrades the version 3 crossover, and replaces the tweeter faceplate with the version 3 Stellar waveguide. 

Reference Upgrade Options

Detailed, multi-domain computational modeling enables YG to design loudspeakers holistically, with all aspects optimized together. The Stellar waveguide is an excellent example. It is well known that the shape of the cabinet face particularly affects the sound quality of a loudspeaker. Most loudspeaker faceplate design is based on approximate rules and guidelines. With Reference 3, we have been able to measure and model the exact shape of wave-fronts from the Lattice tweeter across the whole audible spectrum and well beyond. We can precisely predict how reflections and diffraction from the cabinet faceplate affect the sound.

This has enabled a much more complex and precise design of the tweeter waveguide in Reference 3, with a unique, proprietary profile optimized to the Lattice tweeter’s emission pattern and the faceplate shape. The waveguide is elliptical, defined by over twelve million points to a precision of 0.001mm in three dimensions. Its exact flare is optimized at each angle to create an exceptionally wide angular range over which the tweeter output is as even as possible—in both amplitude and phase.

The beauty is that, from the front, it looks so simple: the combination of the elliptical waveguide and the faceplate curve makes a perfect circle.

Cut into the waveguide are ultra-precise grooves that widen from the edge of the tweeter to the waveguide’s outer edge. Optimized through modeling, these break up reflections from the waveguide surface, delivering a clearly audible improvement in holographic imaging of the Lattice tweeter.

These catch the light, especially in a silver finish, looking like rays emanating from the tweeter center. Hence the name “Stellar”.

Upgrade Process: The Level 3 upgrade requires returning the speakers to a YG facility for thorough testing. If transport is a serious issue, with Sonja and XV models, we can limit the modules shipped to the module containing the tweeter and crossover components only. However, this limits the extent of testing we can conduct at YG.

Faceplate Finish Matching

While anodized aluminum is an exceptionally robust and stable surface finish, it will change over time—in particular if the speakers have been exposed to sunlight or other environmental factors. When first fitted, the upgraded faceplate finish may not be a perfect match for the other panels in the speaker. In particular, please get in touch with us to discuss the feasibility of upgrading any speaker with a special finish or custom color. 

Reference Upgrade Options Upgrade Compatibility

While the Level 3 upgrade is available for many of our past models, there are a few cases with very early versions where it conflicts with the cabinet design. In these cases, we sometimes have special solutions to propose. We need the model and serial number of your speaker to verify that this upgrade is possible and to prepare the wiring for optimal operation with your loudspeaker. Over time, the internal wiring and connections of our speakers have evolved, and we will build the upgrade to match your speakers’ configuration.

Binding Post Upgrades

Background

Like everything else in our speakers, the binding posts we use have evolved. We are constantly looking for opportunities to improve performance, and the choice of binding post can have a clear impact. Binding post upgrades are not included by default in Reference 3 upgrades. Many of our users have existing cabling that may rely on their current binding post. Changing binding posts must be performed at a YG facility. This is for two reasons. Firstly, we have to re-terminate the internal wire to match the new binding post. We use an extremely high-pressure, solderless compression termination, which we have found to offer the highest sound quality. This requires facilities in the factory to carry it out and subsequently test the termination. Secondly, the binding post itself is part of the cabinet’s air seal, requiring meticulous fitting and subsequent testing of the seal. Upgrade Process: If you would like your binding posts upgraded as part of the overall upgrade, please contact us for a custom quote. If you select this option, every module with binding posts must be shipped to a YG facility.

The next step

I decided to go with the level 3, Full Upgrade package. Within the next few weeks, all arrangements were made with the YG factory: a date/time window to complete the upgrade and round-trip shipping arrangements. I hired help to pack each 320-pound speaker into four crates, tie them down on a pallet, and ship them to the YG factory in Avada, CO. YG Acoustics was very good at staying within the estimated turnaround window for completing the upgrades. I got my speakers back within 3 weeks of arrival at the factory. Those guys in the factory know exactly what they’re doing. I was also provided with periodic updates. Once I received the upgraded speakers back from the factory, my hired crew uncrated them and assembled them in my listening room. I was too exhausted to even think about hooking them up for a listen. It took me a couple of days to have the energy.

Results

Nothing I can write will do complete justice to what I heard over the next 2 months. When I heard the Hailey and Sonja 3.2 versions at various audio shows, I was stunned; however, nothing can compare to hearing the Sonja 3.2 in my personal space/environment. Having the luxury of capturing and putting into words what the new speaker upgrades were now capable of, especially while listening to familiar recordings, stretches the limits of my writing abilities. However, I will describe what I and others experienced from the Sonja 3.2 upgrade.

In my audio system, I use four different music sources: a streamer, a turntable, a CD Player, and a reel-to-reel tape deck. In the next couple of paragraphs, I will provide a brief sample of each source output from what I heard through the upgraded YG Sonja 3.2.

Pink Faun 2.16 Ultra Steamer: I have written about Herbie Hancock’s 2007 Grammy Award-winning “Joni Letters”. It is one of my favorite recordings to listen to when I write reviews. Track 7, “Solitude,” is a sweet, tender ballad composed by Duke Ellington. It contains some unusual moments in its drifting structure. The nearly seductive interplay of the cymbals and snare drum is almost erotic, as well as amazing. This song is one of the best tracks for focusing on high- to mid-frequency sounds. The upgraded Sonja 3.2 speakers did not disappoint. I was not prepared to hear what I heard compared to the previous Sonja 2.2i; I heard a more relaxed, organic 3D cymbal sound, without any fatigue or ringing. The cymbals were fast and reverberant along with the rest of the musical ensemble. No other speaker in my listening room has ever captured this difficult resonance as well as the Sonja 3.2. The rest of the recording never missed a beat, the best I’ve heard from this outstanding digital recording.

Another favorite that I would be amiss not mentioning was the Ray Brown  “Live at the LOA Summer Wind”, featuring pianist Gene Harris, and Jeff Hamilton on drums. I singled out this excellent CD simply for the outstanding solos by pianist Gene Harris. Mr. Harris takes a blues-drenched approach to the “Mona Lisa” track, providing a powerful bluesy keyboard explosion that, when played through the Sonja 3.2 midrange and tweeter drivers, was worth the price of admission. It pulled me and my bro-in-law into the live recording to the point where we were high-fiving each other, kicking and screaming, with looks of disbelief and moments of validation of what we were hearing—a must-own recording for true jazz lovers.

Esoteric K-X01D CD Player. While listening to the 1994 Patricia Barber “Café Blue CD through the Sonja 3.2, it was game over. I had heard everything before the upgrade, but now on a grander scale. Anyone familiar with this recording knows that the music ranges stylistically from sophisticated pop sensitivities to the avant-garde. Listening through the Sonja 3.2 speakers yielded haunting, contemporary vocal presentations. Patricia’s dark vocals, along with her fine keyboard playing, were delivered smoothly and effortlessly, with enjoyable sonics throughout. This CD will reveal what your system is capable of when played at higher volumes. The upgraded Sonja 3.2 did not disappoint; it captured and delivered everything.

Pro-Ject RPM 10 Carbon Turntable: For the following short sample, I wanted to change from digital to analog. I used my turntable mounted with a top-notch Van Den Hul Crimson cartridge. I selected the 1980 Steely Dan “Gaucho” UHQR vinyl recording. The best comment I can make about playing this UHQR 45 rpm vinyl is that if you use vinyl and don’t have this recording, you are definitely missing out. This recording blends smooth jazz-pop with unforgettable lyrics and sonics. Playing through Sonja 3.2, the outputs of each selection were smooth and controlled, very meticulous and exacting. I never felt this strongly about this recording when played through the Sonja 2.2i speakers. With the upgraded 3.2, I could hear more emotion in the music.

Otari MX5050 Reel-to-Reel Player: The next input source used was the Reiner, Chicago Symphony “Song of the Nightingale.” I wanted to capture the sonics from a pre-recorded tape source. The 1960 Chicago Symphony recording of Stravinsky’s “Song of the Nightingale“ in Scheherazade exhibited a plethora of complex strings, cool winds, and tight brass, all captured on analog tape and delivered through the Sonja 3.2 speakers. This moment took me back to the very beginning, and what I heard at the 2008 Rocky Mountain Audio Fest reminded me and re-validated why I was captivated by the YG Acoustic sound. The Sonja 3.2 does a fantastic job of recreating symphonic instruments without fail. The phase aspect of the speakers mimics those without crossovers, and the strong attributes captured include a wide soundstage, plenty of air between instruments without a touch of blandness, and zero distortion. Not too lush, broad, and full of teeth.  

Wrap Up

When shopping for speakers to purchase or upgrade, consumers have a plethora of choices. The downside of shopping for speakers, especially in the high-end, high-dollar variety, is that the process can be difficult at best. The process is usually accomplished at your local dealer, at an audio show, by reading reviews, etc. The tricky part of listening at an audio show is filtering out all the noise and distractions, which can be very challenging at best. When reading a review, one must rely on the writer/reviewer’s opinions and feedback. I once read a review that suggested, “Operating the Sonja speakers using a tube amplifier with 300B tubes would not work due to the Sonja’s requiring much power.” How far from the truth was that statement? I get more than enough output using my Sonja’s and Thrax Spartacus 300B amplifiers.

The YG Acoustic Sonja 3.2 speakers are very efficient. Yes, they do get better with more power; however, I have never been overwhelmed by listening at high volume. I highly compliment YG Acoustics on their quest for perfect performance. With the upgrade to the level 3 version, they hit the ball out of the park. This upgrade has delivered a 25% performance increase.  My journey with YG began with the 2.2i, which I upgraded to 3.2, and it was well worthwhile. In fact, given the type of company they are, I expect there will be a version 4 sometime in the future. YG is just that type of company. Whether you’re an existing YG Acoustic speaker owner or not, I highly recommend owning a pair of their version 3 speakers. It will change your world. If you are interested in an upgrade or have questions, please get in touch with your dealer, the YG distributor for your country, or contact YG directly at info@yg-acoustics.com
