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."

It’s just the three set of jumpers from board to board that are wired with short discrete silver wires. This is in place of the standard thin gauge ganged copper jumper connections. The O-Ring transformer powering the analog board is wound with silver plated OCC wire. I’d guess you’d call that attention to detail.

 I’d guess you’d call that attention to detail.

Yes, and in my experience it is this  type of attention that makes a difference for the better sonically. Those seemingly small details matter.

I imagine if the 005 came with both silver and copper jumpers, the users could fine tune the overall sound of their system. 🎶 Excellent thread.

I do like combo of silver and copper throughout system, about 50/50 at present. As system has progressed over the years increasing amount of  silver added. My 300B monoblocks use vast majority silver wire, including output transformers. I've found silver has both greater refinement and extension on top, copper added for fuller mids and bass, silver also helps with articulation in bass.  Silver plated copper also very nice in certain places.

 

I recall a time when I couldn't stand virtually any silver in previous systems, always added unwanted brightness in highs, thin mids and bass. How times change!

I’ve been doing some reading about the Musetec 005 and I am getting a very strong suspicion that the designer/builder may have actually listened to each part during the selection/rejection decision making stage.
1 Audionote Kaisei capacitors along with the Mundorf in the power supply.

2 Silicon carbide Schottky diodes.

3 Gold and silver foil capacitors in a discrete (No Op-amps) analog output stage.

4 As mentioned earlier, solid silver wire rather than cheaper thin copper traces to connect various boards.

5 Particular attention paid to clock implementation.

6 What seems to be an overbuilt power supply.

In my opinion these are not casual choices. Someone had to at some point do some comparative listening testing to choose these types of parts. This tells me that whom ever did the actual decision making seem to rely on listening to parts rather than solely a reliance on how they measured.

Perhaps  it is just me, but I find this very impressive. Who ever it is that did final part selection chose some really good quality pieces. It’s easier now for me to understand how this DAC fared so well up against the Bricasti M1 SE. Someone was serious about building a high quality DAC.
