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."

@arafiq -"Also, since I'm using a tube integrated amp anyways (Audio Hungary Qualiton a20i), I think the 005 will provide the perfect yin for my yang :)"

I have a tube based system and you are spot-on.

@arafiq We had a DAC in common in the past, which we both liked. The 005 is a different animal. Incredible sound, it just keeps sounding better with more hours. I must be around 200 now. Give it a much burn-in as possible in your 30-day trial. I noticed it was a great DAC at under 100 hours but it does sound even better now, especially the bass.

After 005’s arrival, first day I just checked it works properly. Yesterday I made some power cords and interconnects to put 005 in my system and make one empty inlet in my Stella P3 regenerator. Partly because its predecessor was ADI-2 pro whose audio io is phone jack, it took some time and labor. I had to rearrange gears and cables. It took some time to make it sound and some aspects of the setup are changed.

One minor trouble was that I once failed to update 005’s firmware. Pushing the flash erase button makes the unit not recognized as an USB audio device. After the firmware rewritten it is detected by computers again. But according to Jinbo, 005 is delievered with the latest firmware already so update is needless!

So I had some hours of listening session today and I’d like to say shortly. Its details and soundstage is great. It renders depth and layers and fills the whole space behind speakers even at quite low volume. Microdetail is superb, as many said you’ll very frequently notice what you haven’t heard yet in your familiar tracks. Dynamic constrast is also great, I can turn down the voulme further than I used to with ADI-2.

Sound color is very composed, doesn’t glitter excessively. Texture is not silky, in analogy sometimes it reminds me very high quality linen fabric. Sometimes it felt coarse, but after several hours it began to be more liquid I think. Is its sound accurate? I’m not sure yet, but I think its sound is of very high caliber and taste.

Some glitches, sometimes DoP does not work and it makes very loud pop. I coundn’t find the right routine to make it sure to work yet. (It’s partly because I use digital volume with my old mac mini and Audirvana. DSD works better with 005’s internal volume while pcm is better with Audirvana’s noise shaped volume. So switching between DSD/pcm is quite complex and some danger there. Right now I’m attenuating about -20db with 10k resister divider and further -6~-20db with digital volume. A passive attenuator might work in my case.) Another glitch is that some tracks pop with DPLL level 1, it is not consistant and the same track is sometimes ok and sometimes it pops, I don’t understand why...

So it will be a long way to put everything right, but I think it’s promising.

Popping on DPLL due to some issue in your network, try 2 and up, if nothing here for sure network issue. Coarsness will go away in time. System willing, 005 extreme resolving capabilities will provide inherent sound staging and imaging abilities giving illusion of performers in room. Even without the refinement that comes later, and can be added to one's system, this dac extremely engaging. I've never been able to play this dac while multi tasking, even at low volumes attracts my attention.
