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."

The first clock I swapped to in the LKS was the Accusilicon AS318-B-100.

Yes, it was an improvement, more forward sounding and clearer. At the time I had an Anthem D2V preamp & Emotiva Monoblocks. That combo along with my B&W Nautilus 803’s which are fairly bright already wasn’t really ideal for me. The Crystek removed the listening fatigue from the equation.

Since then, I now have a McIntosh MX150 pre & MC312 Amp. The McIntosh/B&W combo is really a match made in heaven for me. I could listen to my system all day, it really sounds great to my ears.

It would be nice to swap the clocks again. However, I dread remorking the LKS again. I have so much fear of ruining it as I like it so much already. I try not to follow the long thread on Headfi any longer as the mods to this unit continue on. Although I have professional rework personnel at my disposal at no cost, I try my best to leave well enough alone on the 004 as it stands ;)

 

I have already ordered the Teradak combo with the 13A power supply: https://www.ebay.com/itm/184685139541

I will post again when it arrives. Thanks for all the suggestions.

 

 

Curious, are any of you using your -005 with DSD512 material? I have a highly modified LKS -004 with a Kitsune Singxer SU2. I am using the  SU-2 i2s to feed the -004 from a Mac Mini, running Roon/Tidal and HQ Player. I am upsampling  everything to DSD512/ASDM7/poly-sinc-xtrr-mp-2s via HQPlayer. I really couldn't be more happy with the sound, just wondering if there really is more to be had with the-005.

 

The rest of my system: McIntosh Mx-150/MC312 B&W Nautilus 803's

LKS-004 mods are::

1) Replaced the metal oxide trimpots for the IBV section with metal foil Vishay VFR 1240W pots
2) Swapped crystals to Crystek 957X on both the Singxer SU-2 and LKS-004
3) Had I/V resistors custom made by Texas Components 2 Watt Vishay TX2575 0.1% .
4) Analog section power filter cap replaced with Mundorf 10,000uF 63V MLGO Mlytic AG
5) Swapped to low leakage Schottky barrier diodes Vishay MBRF10H100 100V 10A
6) Vcom bypass capacitors replaced with Wet Film capacitors
7) Replacement of 0.1uF WIMA polyester caps with 0.15 uF WIMA MKP Polypropylene caps
8) Metallized mylar/polyester caps on the analog final/post filter replaced with polyproplyene caps

I am using a Sonore Ultra Digital with LPS after the MAC M1 Mini. I believe I can only do DSD512 via I2s with it, DoP is limited to DSD256 via USB I thought? The difference between DSD256/512 is simply night and day, amazing. The LKS really shines with DSD512 which is why I was curious if any of the 005 users were using it.

I don't believe they offer an LPS mod for the KItsune SU-2?

The Mac M1 Mini is dedicated for HQ Player and Roon only. It's been working flawlessly thus far

The company I work for assembles printed circuit boards. I would have to agree, what I see inside the -005 looks very impressive, just wondering if I should put my dollars elsewhere

 

@sns

Thanks for your input

I see an LPS and Teradak are available for the latest M1 mini, could you point me in the direction of what does Uptone offer for this?Why do you feel the M1 is inferior to a Nucleus or NUC? I tried both , neither could process DSD512 without dropouts.

I’m going to confirm the Teradak will work.

Just an FYI, I built a NUC8i7BEH with ROCK installed. It stuttered like mad  upscaling practically everything to DSD512. That was the reason I tried the Mac M1 mini, pleased with the results to say the least
