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."

@turcoda Let’s see if we can get your 005 fixed. Here are a few suggestions.

1. It’s going to take a full 8 weeks to burn in.

2. If you are using a Windows computer you must install the Windows ASIO driver, Apple or Linux don’t need drivers.

3. I suspect you may have put the DVD sound HDMI cable into the I2s/HDMI input on the 005.

4. If you are feeding your DVD sound out into the 005 and then an amp/processor you need to exit the DVD using RCA/COAX Digital or Toslink into the 005 and then use the RCA or AES/EBU analogue outputs into your amp/processor.

I can only surmise on your situation, if you can give a more detailed explanation of your system that would help.

@turcoda
Sorry to hear about these difficulties. I have been using this device for over a year now with absolutely no problems. I use it primarily to play music but have used it with videos, both from DVDs and streams, though with my set-up sound for those those go in by spdif. This is the first I’ve heard about any extended difficulties either with the 005 or the earlier 004 which I had for 6 years, also with an Amenaro board. There was one problem reported here installing the Windows driver (fixed immediately) and some had questions about the DPLL settings.

The first thing to determine, I think, is whether your 005 is defective. It would be the first defective 005 or 004 I would have ever heard of, but it is possible. Second, you say that you have been playing it for 3 weeks. That might still not be a full break in but it certainly IS enough for you to know how it sounds. If this $3K DAC it doesn’t satisfy your needs far better than a $1K DAC and you have the opportunity to return it, then perhaps you should. After all, SQ is the bottom line. Same if it is defective.

You wrote earlier about your concern regarding galvanic isolation which has principally to do with the relationship between a USB input device (like a computer) and the USB receiving board, like the Amenaro. You sounded very much like you know exactly what you wanted. The Amenaro is one of the two promenent boards used in most of the best performing DACs. I would have supposed, based on what you wrote, that you would have investigated Amanero to see if it would meet your requirements.

At this time I use a SOtM device as a DLNA bridge betwen a small lap-top computer running JRiver and the DAC. However when my 004 was new, the computer was plugged directly into the DAC. There was absolutely no background static at all. There was no noise that I could hear at the time, though when I added the SOtM bridge it did sound quieter. The DAC’s behavior in that regard was exactly as it should have been IMO.

You should have no driver problem at all. But that’s a local issue between you and Windows, I assume.

There are plenty of folks here who would be happy to help, and I’m sure they’ll be chiming in. But as has already been suggested you need to describe your set-up in detail.

Good luck in dealing with the issues.

@turcoda the DAC is Amazing... Get your laptop squared away (preferably ditch your laptop entirely).

@lordmelton is 100% right with his troubleshooting advice. Man knows his stuff.

Don't get discouraged the 005 is well worth the 3k price (double or triple IMO).

Quick hip shot from the Tambaqui vs 005 slow roll testing. Center image Tambaqui really shines. I'm literally pausing tracks, going back, and am just like "man I never heard the vocals so dead center before".

Really enjoying the Tambaqui, 3k vs 13k enjoying the Tambaqui... Well... Ugh... Probably not so far...

I've done a TON of headphone listening with both the 005 and Tambaqui and again, Tambaqui (with HPA4, and 005 for that matter) definitely ups my headphones to the clarity, channel separation and low frequency bass speed/control of the my reference Stellia's. literally my Z1R's sound 90% like my Stellia's in the domains of the high frequency and low frequency. Stellia's have unfortunately obnoxious separation now with the Tambaqui and somewhat fatiguing detail (but never had the Z1R's sound staging to begin with). So in my own personal case that's a potential $1,700 cost savings on cans. People will probably disagree, but just my hot take.

So Tambaqui has right out of the gates (in my opinion equivocated to $$$)

Roon Endpoint ($500)

Better Headphone listening ($1000) with the multiple amps (SPL, Benchmark, RME, Sony Tazy I've tried)

Excellent app ($250)

Size and aesthetic ($500)

So gateway Tambaqui price is now creeping ever so slightly down to maybe 9-11k mark, but still way up from the 3k 005.

I'll again keep dumping "as I go" impressions here, along with a big deep dive review of them both.

@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.
