Musetec (LKS) MH-DA005 DAC


Some history: I was the OP on a four year old thread about the Chinese LKS MH-DA004 DAC. It achieved an underground buzz. The open architecture of its predecessor MH-DA003 made it the object of a lot of user mods, usually to its analog section, rolling op amps or replacing with discrete. The MH-DA004 with its new ESS chips and JFET analog section was called better then the modified older units. It has two ES9038pro DAC chips deliberately run warm, massive power supply, powered Amanero USB board, JFET section, 3 Crystek femtosecond clocks, Mundorf caps, Cardas connectors, etc., for about $1500. For this vinyl guy any reservation about ESS chips was resolved by the LKS implimentaion, but their revelation of detail was preserved, something that a listener to classic music especially appreciated. I made a list of DACs (many far more expensive) it was compared favorably to in forums. Modifications continued, now to clocks and caps. Components built to a price can be improved by costlier parts and the modifiers wrote glowingly of the SQ they achieved.

Meanwhile, during the 4 years after release of the MH-DA004, LKS (now Musetec) worked on the new MH-DA005 design, also with a pair of ES9038pro chips. This time he used more of the best components available. One torroidal transformer has silver plated copper. Also banks of super capacitors that act like batteries, solid silver hookup wire, 4 femtoclocks each costing multiples of the Crysteks, a revised Amanero board, more of the best European caps and a new partitioned case. I can't say cost NO object, but costs well beyond. A higher price, of course. Details at http://www.mu-sound.com/DA005-detail.html

The question, surely, is: How does it sound? I'm only going to answer indirectly for the moment. I thought that the MH-DA004 was to be my last DAC, or at least for a very long time. I was persuaded to part with my $$ by research, and by satisfaction with the MH-DA004. Frankly, I have been overwhelmed by the improvement; just didn't think it was possible. Fluidity, clarity, bass extension. A post to another board summed it up better than I can after listening to piano trios: "I have probably attended hundreds of classical concerts (both orchestral and chamber) in my life. I know what live sounds like in a good and bad seat and in a good and mediocre hall. All I can say is HOLY CRAP, this sounds like the real thing from a good seat in a good hall. Not an approximation of reality, but reality."

the Singxer UIP-1 PRO has just been released and should do the same job as the INNUOS PHOENIX at a tenth of the price. has anyone had the opportunity to insert one of the two devices between the usb straeamer and the dac?

Singxer is a Chinese company with a sterling reputation.  Their most popular product over the years has been a USB to I2S converter that is competitive with a similar one from LKS.  

The Singxer UIP-1 PRO ($280) and also the Innuos Phoenix ($3750) are USB in and USB out reclocker devices that we used to call decrapifiers or USB pipe cleaners.  Long ago I used such a device made by Intona and there are many makers of these at present.  The two mentioned here seem far more sophisticated as each has a 24MHz OCXO for a reclock of the USB data lines.  Each, no doubt, also regulates the 5V line, though that has no impact on the Musetec as it generates its own 5V and doesn't use USB line 1.  The Innuos is made in Europe and is in a large case that is filled mostly with an LPS.  There is a small circuit board, similar in size to the circuit board in the Singxer, that does the actual USB cleaning.  The board in the much smaller Singxer seems to have the advantage of galvanic isolation as there are definitely two distinct parts to the circuit board separating the USB in and out.  To make these devices comparable one would have to substitute a good 7.5 V LPS for the Singxer's wall wart at an additional cost..  

As many have written here, the Musetec seems to be optimized for USB with custom clocks in the USB input circuit as well as at the D to A stage.  Also, many of us use streamers that include reclocking.  Whether stand-alone reclockers like these can make a meaningful difference in your system can only be known with a trial.  Given the pricing, the reputation of Singxer and the descriptions of both, the Singxer looks like the better option of the two, by far.  If you try one, please pass along your impressions.

It looks like 6V is being recommended for an LPS for use with the Singxer UIP-1 PRO.  Saw this at Kitsune.
