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."

@sns  I am talking about the power supply feeding the PF/Jcat usb/I2S card. The network card (I use Jcat net Xe as well) is equally important. The ATX power supply is a whole different ball game and that power supply is as much critical in the equation. My server is a 3 box solution and I have invested a lot across all these power supplies alone. I don’t want to deter too much with server discussions in this thread but from experience what I can tell is the quality of power supplies rules the digital world.

I totally agree.

 

The only reason I go off on tangents with this thread is because of the great potential of 005. In the context of streaming, full potential of 005 requires totally optimized streaming chain. With dacs used for streaming I perceive dacs as only parts of a whole, analogous to amp/speaker integration.

yes, you would be surprised what a great front end can do to a DAC. Many times we change DAC thinking that it will bring better sound and more than often its the source that limiting the DAC from performing to its full potential.

The Amanero board within the Musetec does the conversion from USB to I2S just like the external boards. It does that with an excellent power supply using super-capacitors, and clocks...

 

Yes, all USB boards, Amanero or XMOS or JLSounds does this as this is the only way to talk to the ESS. In other words, its a small DDC inside. What matters is the clocks, power supply feeding it and isolation. With an external DDC, you bypass the additional processing inside and go almost directly to ESS. The theory is this additional processing can put strain and induce noise/jitter on the chip. Even MSB has an external ProISL interface which converts USB to Optical. I strongly believe that DAC manufacturers should take all these into account when designing a DAC of great quality. Though USB was not meant for Audio interface, there is nothing wrong when designed right.

In the Musetec, the ESS chips, together with its regulating clock, are on the analog board  That board is powered by an elaborate LPS headed by the silver plated O-Ring transformer.  That LPS powers nothing else in the DAC.  The Amanero Board, together with its own 3 clocks are on a separate board.  That board is powered by an entirely independent power supply at the head of which is a second transformer, a toroidal, feeding into a bank of super capacitors that act as batteries.  That PS powers nothing on the analog board.  This goes about as far to insulate the ESSs and their own clock from any strain, noise or jitter from the USB input circuit as I can imagine.

Nevertheless, anything is possible in audio and there are rarely any hard and fast rules. So people are feeling the desire to experiment and we'll all be the better for their findings.
