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."

@lordmelton, please relax.

I'm not sure where you're getting your information, but it is quite incorrect.

After all this is a hobby. Don’t take things seriously and personally."

I agree completely. If I may, I suggest that everyone relax - and perhaps hold off on the name calling.

Btw, also I didn't state that the DA005 doesn't meet standards, or that ASR doesn't like the measured results (which is definitely true :-).

What I pointed out was IF (and I emphasized the IF) the measured performance is correct, then it doesn't meet the specs claimed by the manufacturer. That seems like a reasonable observation to me. No?


This is my follow-up to the publication of Jinbo Li’s short letter yesterday and his more extended communication this morning.  He is the designer/engineer and manufacturer of the Musetec DAC.  After a day of reflection I’m becoming more and more appreciative of the normally taciturn Jinbo who says, effectively:

Any old competent engineer can design a DAC that tests well.
I’m interested in music, so what I do is try hard to design a product to sound good. Period. Measurements notwithstanding. They just fall out, and are what they are.

For example, as one user has written elsewhere, "the majority of the distortions comes from the discrete I/U and output stage. The output amplifier and buffer has no feedback (I think). Without it the distortion values cannot compete against integrated op amps."

I would not have him change my own DAC to meet the need for a better specification.

I wonder what the audiophile public will make of a product that is designed only by listening without reference to tecnical specs, and that does not publish technical specifications. One thing it may do is to define better the term "audiophile."

I did advise him that when you publish technical specifications you invite tests that should confirm those specifications. So perhaps he should revise that part of his site.

@sns
I suppose we’ll have to wait and pose the question when he puts forward an option. My guess is that it will compromise sound. I’m not certain why he is proposing to go in that direction. I know he has always felt a great obligation to his customers.
