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."

Real time upsampling to DSD512 can require a lot of processing power. Using the ASDM7EC modulator with the more intensive filters is too demanding for most consumer CPU's. In fact, offloading the filters to a powerful GPU is needed as the CPU alone is not enough. Something on the order of an i9-12900k with RTX 3080 might get the job done. Far from an inexpensive or basic computer. Forget about passively cooling such a rig.

The non-EC modulators and lighter filters are significantly less demanding, so a less powerful system might do it. DSD256 also presents less load.

That's true. My 2011 MBP with dual core i7 can do DSD128 through Roon without much struggle, although Roon's modulators and filters are lighter. I haven't tried DSD256 or higher as my DAC is limited to 128 DoP. General rule (at least in regard to HQP) is doubling the sample rate doubles the load on the CPU. I brought up rigorous processing criteria because @fmzip uses HQP and reported a NUC was insufficient for DSD512 even with the non-EC modulator. HQP really is a different beast when it comes to DSP.
