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."

Supercapacitors, like all capacitors, have a limited lifetime. In the case of supercapacitors it’s usually measured in cycles, the ones in the Musetec for 500,000 cycles. It’s hard to know what that means for normal DAC use. As you know in the Musetec there are two sets of supercapacitors that are charged alternately--should probably lengthen life. In any event, the controller might charge more frequently as they slowly lose capacity. They are not very expensive and not very hard to replace. But I suppose that’s a reason to put the DAC into standby mode between listening sessions.

As I have tubes in my system, I turn it on an off (standby) with the tubes (some also on standby).

sns, my amp hasn't been plugged into the Euqi Core in months.  I was just commenting that the Equi Core handled everything including my amp with no trouble, I didn't clarify that it hadn't been in there in awhile.  It sounds way better out of the wall.  

does the unit burn in  on standby mode?, because I was playing on sending a signal through mine 24/7 for about 3 weeks.

Well, it may depend upon what you mean by burning in.  All the inputs are digital so there is no signal going through on stand-by as there is no power being supplied to the digital circuits.   The analog circuits I suppose are being kept "warm" with stand-by.   I do not know to what extent that constitutes breaking in.  I would think that leaving it on with signals going through for three weeks is overkill, but not a lot of wear in the scheme of things.  You'll propbably get 90+% of break-in in the first 100 hours or so.  Perhaps the engineering types will chime in here with a better answer.

Curious if any of you have compared the Musetec to a comparable tube dac?
