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."

I think track pops have reduced by adding ground connection to my mac mini which was lost when its power was changed to an LFP battery (formerly used with ADI2 pro). Not sure if they vanished completely but after that pops didn’t bother me. Amanero is more delicate than other USB interfaces?

 

Re DoP, I think 004 didn’t have an option to turn off DoP, while 005 has. DoP glitches continue, but I think turning off and on DoP function again solve it in most cases. Another glitch with DoP/Audrivana is it produces a loud pop (quite high fq, while the not working DoP pop is low) in only right channel when playing DSD file is stopped and Audirvana loses its grab of the audio device. I think these glitches with DoP due to Amanero, maybe that is why it is not so commercially popular in spite of its reputation of great sound?
 

Regarding 005’s tone and texture, IMO being not silky is by no way its shortcoming. Its sound is completely opposite to ostensibility or intended splendor in spite that it is extremely detailed. I think this is the most interesting point in 005’s performence, but its tone is changing (so I don’t worry about its coarseness much) and it’s too early to be determined about its tone.

I think I found the condition of DoP glitch, setting Audirvana volume option to ’software only’ seems to turn the DoP mode of 005 off. Changing volume control method between pcm and dsd requires some care.

PS/Edited: I tried again but I couldn't reproduce it! My applogize for confusions. @jc4659 Would you try yourself and report your result with Audirvana volume options and DoP when 005 arrives? 

Not specific to this DAC, but in general digital volume controls can cause issues with data flag recognition (i.e. PCM, DoP, or native DSD) since the digital data is modified which may impact the selected format identification.

In Audirvana there is a "Native DSD Streaming Method" setting. You can choose from the following 3 choices (in my set up):  1) None: convert to PCM, 2) DSD over PCM 1.0, 3) DSD over PCM 1.1  What do you have that set to? If you have chosen "None: convert to PCM" then you are asked "DSD convert to PCM with boost of" and your choices are 0dB to +6dB in 1dB increments.  If you chose either of the other two DoP settings then the volume boost is not an option.

Under the Upsampling category, what do you have the "Safe volume reduction before DSD upsampling" set to? Choices are None thru -6dB in 1dB increments.

Under the Audio Volume category, I chose "No leveling" and software volume control turned to "Off"

I should add that I do not yet have the DA-005 and so don't know if the Audirvana software will alter the default settings/choices when it sees the new DAC.  I'll let you know how I set mine up and if I get volume pops.
