Marigo Audio Lab L3 Isolation Platform and Composite Base by Miike Girardi



Giradi2.jpgThis review is the first on Marigo Audio Lab products that will also include the E3 Mystery Feet and ZSD-31/ZSD-41 SuperDots shortly. The background as to why I have chosen to embark on this quest to evaluate and own select reference component isolation and resonance control products is also covered in that review. Reviewing the Marigo Audio L3 Isolation Platform and Large Composite Base(s) is simply the natural progression in this upgrade path.



Origin250.jpgMarigo Audio Lab offers three performance levels of isolation platforms known as the L1, L2, and L3, increasing layer count and resulting overall thickness as you move up the line. The L3 is the top-performing platform with 40 alternating thin layers of an extremely stiff proprietary custom high-tech composite. The layers are shaped into a microscopic wave pattern, combined with a unique heat-cured resonance damping material. Each L3 platform is machined to a final thickness of approximately 1.5 inches and has a large chamfer machined on the top and bottom perimeter. The chamfers are said to disperse remaining low-level vibrations that can propagate longitudinally within the L3 platform to be dissipated completely. Each L3 platform is finished with a proprietary formulated organic lacquer which requires several days for each coat to dry. According to Ron Hedrich of Marigo Audio Lab, it took ten years of R&D to complete the development of the L3 Isolation Platform. The L3, with its unique cross-sectional shape, was designed to be used with any component isolation footer system and will provide the optimum foundation to get the best performance from the E3 Mystery Feet. I would describe the L3s as very heavy for their size and are beautiful in appearance.

Enhanced performance of the Marigo Audio Lab E3 Mystery Feet can be achieved by adding one Marigo Audio Lab ZSD-41 SuperDot or composite bases (LRCB) under each E3, with the LRCB being the higher echelon component. A set of three or four round-shaped LRCB positioned under a component with a corresponding Marigo Audio Lab ZSD-31 SuperDot is cost-effective to E3 Mystery Feet. They are best suited for small component footprint applications such as Internet routers, Grounding Boxes, NAS drives, and linear power supplies but can be effective on larger components. Like the Marigo Audio Lab SuperDots, the LRCBs comprise custom-produced composite materials stacked in a proprietary layer stack and result from refinement based on numerous iterations and dedicated listening tests. Optimization of the rectangular-shaped (2.75″ x 4.25″) LRCBs is achieved by individually rotating their position or angle relative to the component central axis.

This review will evaluate the Marigo Audio Lab L3 Isolation Platforms against butcher block maple amplifier stands, including installation in an existing butcher block maple rack. Later I will build upon the review with the incorporation of LRCBs stacked under Marigo Audio Lab E3 Mystery Feet as previously installed in my system.

I started by installing the Marigo Audio Lab L3 Isolation Platforms under my First Watt SIT-1 monoblocks that were originally isolated with spiked butcher block platforms. Once installed, now in combination with the Marigo Audio Lab E3 Mystery Feet, I heard for the first time an additive synergy of both components in their effect on reducing the noise floor and accurately portraying the previously compressed dynamics. With additional L3s implemented under both chassis of the Ayon Audio S-5 Network Player, there was a newfound coherency in frequency response timing not previously attained in my system. Sans the L3 Isolation Platforms, I now realized how much butcher block maple rings and ultimately colors and compresses the audio signal as a platform material. Adding the Marigo Audio Lab rectangular-shaped LRCBs under each E3 Mystery Feet (5 sets of 3) amplified the effect on my system of accurately portraying the interrelationship of space between instruments and the image depth of each instrument. If the Marigo Audio Labs had a sonic signature, it was the evenness of the frequency response of each instrument and vocal, the naturalness of dynamics, the resolution of microdynamic details, and the natural expression of the soundstage color palette. Replacing the existing brass cone footers and coupling disks with the stacked arrangement of ZSD-41 and ZSD-31 SuperDots (sets of three) under each L3 Isolation Platform was the icing on the cake; a complete transformation in musicality. Given these results and those presented in my review of the E3 Mystery Feet and ZSD-41/ZSD-31 SuperDots, I evaluated all Marigo Audio Lab products discussed for the remainder of the review above as mechanical isolation and component resonance control system.

Blue Maqams (ECM), a 24bit/192K digital download composed by the Tunisian oudist, Anouar Brahem, was first chosen to evaluate the effectiveness of the Marigo Audio Lab product assortment. Blue Maqams represents Brahem’s tenth outing for ECM, and it’s an album that is likely to be of particular interest to British jazz listeners. The quartet line-up features British-born, US-based bassist Dave Holland, who appeared alongside Surman on Brahem’s 1998 trio album “Thimar.” The group also includes the British pianist Django Bates and another first-time Brahem collaborator, the esteemed American drummer Jack DeJohnette.

bluemaqams.jpgBlue Maqams has received worldwide acclaim. In DownBeat magazine, Bobby Reed wrote: “The result is a program that features traditional music from Arab culture as well as more modern jazz elements. The word ‘maqam’ refers here to Arabic melodic art, but also to Iraqi maqam, as practiced by master oud player Munir Bashir. Each musician shines here.” On Allmusic, Thom Jurek observed, “Blue Maqams is lovely. It’s a nearly perfect illustration of balance between cultural and musical inquiry, underscored by this gifted ensemble’s confidence and near symbiotic communication. This is an exceptional outing, even for an artist as accomplished and creative as Brahem.” And writing for The Guardian, reviewer John Fordham stated: “Brahem’s oud often sketches in the themes, sometimes shadowed by the others in dreamy twilight reflections, more often accelerating into languidly swaying night walks such as the title track. Spanish-tinged guitar-like jams end in drum flurries while thumping Holland bass vamps release scintillating jazz breakouts … It’s a real meeting of hearts and minds.” 

Once again, a significant shift toward truthful timbre had taken place on this recording with the full complement of Marigo Audio Lab isolation products. I heard this timbrel truthfulness in the overall tonality ranging from the pitch definition in the lowest octaves to greater clarity in the uppermost frequencies. On the first cut, “Opening Day,” the oud played by Brahem sounded so lifelike and natural, and there was a new sweetness and weight to the piano notes played by Couturier that I had not previously heard. Every instrument sounded more organic to my ears than my previous reference footers and platforms. For the first time, there was a complete lack of smear in the sound of the cymbals. The ringing and slurring of the music that was present before were removed entirely, resulting in coherency in frequency response timing. My listening sessions extended much longer due to the lack of ear fatigue I was not experiencing with Ron’s new products. In terms of audio component upgrades, this exceeded the main component upgrade.

I confirmed in my listening tests that unless all components are isolated with Ron’s unique approach to component isolation and resonance control, you will never hear the true capabilities of their effects or the full capability of your system. Having the crossover-less Cube Audio Nenuphar loudspeakers can be both a blessing and a curse in that any change in your system can be heard, which was the case when I removed the stack of SuperDots under my Google fiber router. Although minor, there was an immediate drop in system performance but not worth the loss in performance in going back to hard-sounding colored brass cones. I also was shocked when I used a single ZSD-41 to isolate the DC power cable powering my router from the solid wood floor. Without the single ZSD-41, floor vibrations were carried from the DC cable to the UpTone Audio JS-2 power supply, which provides power to the router and EtherREGEN switch/reclocker. These vibrations resulted in the delicate ethernet signal stream becoming contaminated by mechanical resonances that were heard as obscuring microdynamics and smearing of fine details.

Beingthere.jpgI recently discovered, Being There by pianist/composer Tord Gustavsen. On this third outing for ECM, pianist/composer Tord Gustavsen comes full circle on Being There. When he signed to the label in 2003, issuing his debut, Changing Places, he and his collaborators – bassist Harald Johnsen and drummer Jarle Vespestad — dug deeply into close-knit quarters, creating a detailed yet expressionistic examination of the more melancholy human emotions. Being There completes a trilogy of elegantly layered, spacious jazz from the most introspective elements. As a pianist and composer, Gustavsen employs only the barest essentials. There is no fiery technique, no gimmickry that will heighten or dampen the mood, no harmonic drift. This music flows from a source, albeit quietly and enigmatically, looking into territory explored on this side of the Atlantic on earlier albums by Brad Mehldau, albeit with a distinctly Northern European voice. Perfect for ECM, the music is cool, almost uncomfortably so, such that when its lyricism is fully given a voice, it often takes the listener by surprise, instilling a kind of silence that breeds wonder rather than detachment. Manfred Eicher’s signature production allows Gustavsen’s piano the sheer deliberation and consideration he requires to put his gorgeous melodies into the air. This rhythm section doesn’t follow his lead so much as flow into it, playing as a single voice, allowing these songs form and function. Gustavsen’s imagery is skeletal, yet he shines light into the darkened corners of those less than celebratory moodscapes, bringing an intricate balance to both lyric and emotion.

Before implementing Ron’s buffet of component isolation and resonance control products, I never connected emotionally to the various cuts on Being There. The First Watt SIT-1 amplifiers are ruthlessly revealing given their design and implementation of the single output device static transistor. Adding in the crossover-less Cube Audio Nenuphars, and you have a recipe for either a lunar eclipse or a cloudy washout day. Ron’s products allowed me to fully relax while becoming one with the mood of the music. They provided the gateway to experience the true intent of each artist and the composer as presented in the recording. I have never listened to my system as much as I have as of late since the adoption of Ron’s excellent products.


“Everything matters,” as the saying goes, and like almost everything else in life today, somebody is always looking to stretch the envelope of what’s possible. With his state-of-the-art component isolation and resonance control products, Ron Hedrich of Marigo Audio Lab has achieved this. A new standard has been set for component isolation and resonance control—my new reference.
