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 Have you ever considered this?

I think I've previously seen it. I'm really done with usb rendering upgrades at this point, OpticalRendu sound quality so amazing, no thought to any more upgrades here. I'd suggest you try the OR so we have comp to an optimized I2S setup.

Or if you want electric bass sounding real as it might in a medium size venue, Steve Lucas in "One Witness" on Ray Montford’s "Shed Your Skin."

@lordmelton  and others using I2S rather than usb. I continue to be intrigued with I2S only because possible theoretical advantages vs usb, this being I2S being native protocol for dacs.

 

I've been searching for servers with I2S, virtually non-existent, motherboards don't have it natively, only diy solutions. One could do atx board build and use Pink Faun I2S HDMI board, bet that's very nice, but requires diy or custom build by another.

 

So most are limited to DDC/streamer conversion, usb still in chain from server to ddc/streamer, thus, not true pure I2S connection from server processor to dac. Also, streamers with I2S out very limited choices, since streamers critical to sound quality, limited availability may mean these streamers not be up to the best quality usb streamers with their much greater availability and variability.  Also, no standardization of pin outs on I2S, so dip switches required for proper orientation, presume dip switches have some negative impact on sound quality. This possible downside could be alleviated with custom built I2S cable, so good there. The final possible downside is I2S clocking within dacs. Since its native protocol, perhaps no extra clocking needed, as used on good usb boards within dacs?

 

As some of you know, I had Singxer SU6, never tried, lack of motivation due to great usb sound quality, also considered some of the technical issues listed above, and others specific to my setup to be theoretical disadvantages vs usb.

 

So my issues with I2S in general, assuming there are in fact theoretical advantages for dacs with I2S inputs. One is no pure I2S available server to dac. Two, no standardization of !2S pin outs or connector type.  

 

Seems to me dac manufacturers should state which input best, I suspect they put greatest engineering efforts towards usb because its input they use in voicing dacs, I2s if included, only for convenience. If they also voiced with I2S, they should state whether superior or not. On the server end of things, manufacturers should devise a method for I2S rendering if there is understanding I2S superior to usb or spdif. Pink Faun manufactures what is likely the best I2S streamer/renderer available, but this is expansion card for atx motherboard only, Baetis only off the shelf atx I'm aware of, otherwise custom build.

 

I don't understand why rendering has to be so secretive, complicated and as yet, objectively optimized. We need dac and server manufacturers working together in optimizing streaming chains, until then we have to guess or rely on the rare direct equalized comparison, difficult to do. I'd love to do an atx/Pink Faun I2S comp to my present usb, would be nice to know 005 preferred port.

I have the 005 for couple of weeks now and it sounds very good to me. I will say that at this price point, it surprised me and concur with what has been already said about this DAC. I am enjoying it as much.

The way the USB sounds, I don't have much desire to move to I2S - my server side USB is very optimized with JCAT USB XE feed with some very exotic power supplies. I am currently trying out few USB cables though that I already have at hand (Network Acoustics, Westminster, Sablon) to see which one has better synergy with the server and 005 - they all sound fabulous in general.
