Zero One Mercury CD/HD player

Life with the Nova Physics Memory player, around these parts, has been grand. In the time I’ve owned it, I’ve not met anyone who has heard it and was not impressed by its sublime sonic capabilities. In my “conclusion” section to the review, I stated, “With the onslaught of computer-based music servers hitting the market, I’m certain it will only be a matter of time before the Memory Player will meet its sonic match as the competition catches up.” Well, that “matter of time” has arrived!

Yep, it was exactly two years ago I wrote that review on the Memory player, and I’ve been listening to another computer-based player for the past six months that readily serves as its direct competition. The company, Zero One, hails from Singapore, and their latest product here under review is the one-box Mercury CD/HD player that will spin a disc or, at the press of a button, download a song or entire disc onto its 750 gig hard drive. The look, feel, and substantial chassis spell s.e.r.i.o.u.s. After three months of uninterrupted play, I would have to say Team Zero is exceptionally talented, a bunch based on how easy and versatile the Mercury CD/HD player’s slick-looking user interface works. Zero One has first manufactured high-end digital separates, such as their Ar38SE DAC and Model Ti48 transport, since 2001. The idea to converge the best of hi-end audio with computers was team Zero’s ultimate goal when starting the company. With all the earnestness and know-how that team Zero could muster, they finally decided to build a single unit.

Visually, the Mercury is large, clean, and sparse since there are no buttons on its faceplate. All operations are done from its remote control which is your typical inexpensive plastic type. The rear panel is where the power button resides, bottom left, adjacent to the male IEC AC connector and a pair of RCA analogue outputs. A SPDIF/RCA digital output is located dead center, completing the rear panel connections. The Mercury boasts quite a versatile platform by way of its user-variable settings that range from its word-length output (16 to 24 bit) with upsampling capabilities from 44.1 to 192 kHz. Selectable dither is a nice option that comes as standard. The four digital filter options range from HQ3, which is Red Book CD standard (i.e., very steep, brick wall-type ), to Purist (very shallow with a high corner frequency). There is also a no-filter option for those who choose not to use any filters or opt to experiment.

The Mercury also boasts three dither options. Dither is a different type of ultra-high-frequency shaped distortion. The software offers a variety of word length reduction modes. They are TPDF or Triangular PDF dithering, Nyquist – high frequency dither, and NShape – second-order shaping. The software performs all its audio processing at 64-bit. To transfer the resulting data to a D/A converter, the samples need to be reduced. This is commonly known as “word length reduction.” “If the data was simply truncated to the requisite D/A length (for example, 16 bits), this results in quantization distortion,” says Heng. To avoid this, a small amount of noise is introduced before reduction takes place. This is known as “dither.” To reduce the audibility of dither noise, it can be adjusted to be louder in areas where the ear is less sensitive and quieter in areas where the ear is more sensitive. This is known as “noise shaping.”

Another novel feature is the IS2 digital connection internally wired between the Mercury’s transport and DAC. IS2 boasts inherently lower jitter measurements (thus noise) by separating clock and data signals, says Heng. IS2 was popularized by Mark Schifter of Perpetual Technologies some years back, but somehow has never caught on despite its claims as a better transferor of digital data.

A well-thought-out, easy-to-navigate user interface becomes immediately apparent the moment you pop a CD into the Mercury’s CD tray and grab its remote. An LCD centered above the CD drawer opens up to a series of options in its submenu. Internally, the Mercury uses the Linux operating system because it is robust and seldom prone to crashing. In addition, the Linux OS was also easy to integrate into Zero One’s proprietary software. The Mercury’s PC section “uses a standard but super quiet switch-mode power supply,” says designer Alvin Heng. The digital-to-analogue section is powered by a separate, fully regulated, linear PSU using a transformer, says Heng, with a much higher VA rating than usually required.”

The Mercury is a feature-laden product indeed, but Heng seems most proud of the modified pro sound-card he designed, stating, “This is a pro audio card that we modified by adding additional supply regulation on the board. It is not mounted directly onto the motherboard as you would normally. Instead we have a proprietary adapter PCB that interfaces between the sound card and the motherboard. This allows us to power the soundcard with its own linear DC supply instead of taking the power from the noisy PC supplies. As far as we know, we are the only manufacturer that has such a sophisticated power supply system for the sound card.”

Once I became familiar with the Mercury’s remote, options like playing a CD, downloading a CD onto the 750-gig internal hard drive, or playing previously stored music became a cinch thanks to the Mercury’s slick user interface. One other thing, having a real-time CD player turned out to be a treat because it offers you the opportunity to listen first to the songs you may want to download – something my beloved Nova Physics Memory player cannot do since I own the transport-only version. This, in essence, qualifies the Mercury as a fully capable CD player, transport, and music server. The well-lit LCD that adorns the Mercury’s faceplate boasts large, easy-to-read fonts for easy reading from my seat 10 feet away. In the end, this further demonstrated how smartly built the Mercury is.

There certainly was a longer-than-usual familiarization period between Mercury and me. Using the remote was a cinch, but I still wish the front panel also sported the redundant Open, Close, Play, Stop, Rewind, and Forward buttons every other CD player has. The scarcity of buttons also made the Mercury’s CD playback somewhat frustrating because you always needed the remote nearby to do something as simple as stop the player. That’s essentially my only caveat about the Mercury. The folks at Zero One have taken into account how precious the remote control is because two come standard. As I found, its sonic virtues far outweighed the oversight of not having Stop and Play buttons on its faceplate. One nice feature is that Mercury sports a particular software called EmDB, which is their compressed version of the Internet’s FreeDB, automatically searches, and (if available), displays the artist name, individual song, and title. The EmDB software, which offers free updates, supports mostly mainstream.

Living with the Mercury has been an absolute treat, no matter the associated gear. I went through a series of electronics that included Tact, Bel Canto, NuForce, and Behold electronics as well as cables from Bybee Technologies, Acoustic Revive, and Orinda Acoustic Cables (designed by Sunny Lo, formerly of Sunny Cable Technology). The loudspeaker that received the most play was the elegant-sounding Volent Paragon VL3 that I awarded my Most Wanted for 2008.

Listening to the Mercury in CD mode granted only a partial view of its sonic capabilities. As a CD player, it performed respectably, but the CD mode still sounds a tad brighter and harsher on most demanding classical and big band material. An excellent example is Sarah Vaughn and the Count Basie Orchestra’s recording of “Send in the Clowns.” Maybe I’m being a little more critical because I’ve lived with the Nova Physics Memory Player and use it pretty much exclusively (and that would make anyone switching back to a CD player sensitive and thus critical of the added stridency heard on these discs). However, I would venture to make a friendly wager that the Mercury was never intended to be critically listened to in CD mode. Moreover, I’ve never heard a CD player sail through “Send in the Clowns” played at a respectable volume without a little bite in the upper frequencies. So then, the real question is, how good is “Send in the Clowns’ when played through the Mercury the way it was ultimately designed to be – through the Mercury in HD mode?

In a word, delightful!

Through the Mercury’s hard drive, Sarah’s voice sounded more like an instrument. Sassy, as her friends called her (not because she sounded so much like a saxophone, because she’d curse you out quick), came to life dynamically in a way that would make one think two different CDs, JVC’s XRCD and a standard pressing, were being swapped out. This unimpeded soulfulness, fluidity, and immense drama coming off Sarah Vaughn’s voice and Count Basie’s big band is documented in jazz history books, so there’s no second-guessing as to whether it exists or not. The trick, however, is getting it out of an audio system. The Mercury, via its hard drive, has an admirable amount of poise no matter the amount of stress or number of instruments. As a result, the soundstage opens up further and more clearly on the extremes, providing notably more air and body around individual performers.

The Mercury, in HD mode, doesn’t quite live up to owning the same degree of sonic finesse and the ultra-smoothness the Nova Physics Memory player imparts on the music. That being said, the Mercury does offer more finger-snapping and toe-tapping rhythm than my twice as expensive Audio Mecca Mephisto CD player – my former reference CD player.

The one thing I’ve rediscovered during this review period is that the standard 16/44.1 conventional CD player, for me, usually impedes on the communicative flow of music. Insidiously, they tattoo musical passages with small bits of grit and glare, making it difficult to sit through an entire performance. The Mercury doesn’t entirely alleviate this “tatooing” effect, but it surpasses any conventional player I’ve heard in HD mode. That says a heck of a lot about this impressive playback system.

We live in a world where exposure is everything. At the same time, nothing is more important than a healthy dose of skepticism. That being said, after living with the Nova Physics Memory Player for more than two years, I’m convinced there’s nothing more precise for getting zeros and ones off standard 16/44.1 Redbook CDs. Nothing. Time has been a good friend to the MP and has since reaffirmed what I originally wrote two years ago. If that wasn’t enough evidence, here comes the $3,500 Zero One Mercury CD/HD player to further strengthen the claims of what computer-based players can do (at a staggering one-third the price of the Memory Player). 

After many months of careful listening and evaluation, I consider the Zero One Mercury CD/HD player a breakthrough in its price/ performance category. Its user interface is well-thought-out and, by comparison, though not its sonic equal, makes the Memory Player’s user interface look primitive. Finally, there’s a less expensive alternative for those who refuse to plop down $12k for a Memory Player/transport. I’m convinced that if you own a CD player and get the opportunity to hear the computer-based Zero One Mercury, as I did, you too might have to purchase it. For a hair below $4,500, I consider it a steal. In my opinion, it will significantly help steer the new way to musical enjoyment in the home.
