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."

@yyzsantabarbara I recall you mentioning 005 not working well with RAAL headphone amp. What is it about this pairing that you don't like, on paper it would seem good match, nice tubes and can run in various modes.

 

 

@sns It is too smooth on the RAAL VM-1a amp. This amp and both SR1a + CA-1a headphones can scale amazing heights in sonic quality. With the 005 it sounds way too smooth and lifeless. The Benchmark DAC3B sounds so much better. The VM-1a + DAC3B is not what I call smooth. Realistic is a more apt description. The SR1a is really a miniature 2 channel system, not really headphones.

I lent my 005 DAC to Danny at RAAL-Requisite (one of the 2 owners) for 1 month since I wanted his opinion, given mine was not too favorable. He has an incredible ear and is a former musician. In fact, I recently read a 1 page blurb on Danny’s listening skills on the 6moons web site. So I had good intuition on this. Danny even came to my home and heard my office system (for another project) and gave me some great critiques that I addressed to my benefit.

So it is not just my amateur ears that had an issue with the 005. Of course, I love this DAC on my 2-channel gear and own 2 of them.

Wonder if this some technical issue, for instance impedance mismatch. Certainly doesn't sound like voicing issue as I can't imagine anyone describing 005 as too smooth and lifeless. On the other hand, I can imagine 005 being described  as  excessive in those two qualities.

 

I'd bet adding the Serene pre will improve things greatly, 005 really requires nice pre to reach potential. Fact is I'm still searching for full potential. I received my new ATX board based music server Friday, expecting JCAT Optimio S ATX Monday, should have close to Taiko Extreme performance music server with this setup. Expecting 005 to be perfectly at home in this company.

I do not think the Serene preamp will be much of a difference from the Benchmark LA4, which is exactly what I want to achieve, The Serene has an extra RCA input that I can use. The plan was to get a second LA4 but I am curious about the "better measuring and organic sounding Serene".

The LA4 and Serene are not used with VM-1a headphone amp. The VM-1a has a preamp and amp section already built-in. The Serene and LA4 can used with my SR1a when connected to my RAAL SR1a Amp Interface box. I need to unhook my 2-channel speaker cables when I do this but I have SpeakON cables for both the speakers and the Adapter Box, so it is simple.
