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."

@ja_kub_sz Just a note on DPLL settings for the 005.

Switch to BW01 for PCM and BWO6 for DSD

Also switch off DOP and use the SLOW filter.

Set volume to FIXED.

Looking forward to more updates.

@melm,

Maybe I missed it, but what is the battery for in the 5? 
 

All the best.

Hi, thanks so much for the debugging help.

My current and most problematic issue is the intermittent audio micro stutters I keep hearing. Once they start, they don't stop until I do something to address that.

The 005 is currently plugged into a HEDT worth a bit more than the dac itself. No i do not use a laptop or a streaming device because I dumped all of my funds into this device. I use it for both work and gaming, and, as such, it does contain a fairly high end gpu that is usually the cause of such background noise. This desktop has had more than one high end motherboard and multitudes of other parts swapped out to determine the root cause of the noise, but there was no single one component to blame. It seems its just the way PCs and power supplies are built these days - which really terrible noise isolation... Also, I don't have a free hdmi port to spare, so I'm plugging this directly into the usb input of the dac, which is why i wanted one with an amanero board to begin with.

I am a software engineer and I've already flashed the device and tried the latest drivers to no avail. I do strongly believe its a software issue, as its quite intermittent and random. I think flashing the dac last week and changing some settings alleviated some problems, but some remain. I think im still in the return window, so if I fail to resolve it I'm just gonna pick up something else.

If you want to know the amp im feeing into, its the HSA1B, but for sure its not to blame here.
