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."

@rrboogie I'm biased in that I believe the preamp should be considered as  package with sources, ie. as important as the source itself. 005 potential such that it could benefit from cost no object pre's, I've used 005 straight thru, no pre, with Musical Fidelity M2si integrated, Schitt Saga + and my usual Coincident Statement. Each has pretty large impact on sound, Statement easily surpasses the others. I did prefer tube buffer with Saga +, my go to preference would likely always be tube pre with 005, what with it's neutral to slightly analytical inherent nature.  And my take is spend at least as much on pre as 005 itself, will pay off handsomely.

 

On usb cable front, tried many prior to AQ Diamond, after, figured why bother, high resolving, transparent, nice tonal qualities, whats not to like! If you have problems, its not the Diamond.

 

Leave in standby, no sense in putting hours on components with limited life spans.

 

I have no idea about running XLS and rca outs together, I did try using both outs on prior Auralic Vega, resulted in diminished  sound quality. Makes sense that even if possible, could result in diminished sound quality, analog output stage doing more work.

Not a good idea to use one set of interconnects from DAC to sub-woofer and another to preamp. One set to preamp and two sets out from preamp to amp and sub-woofer, even if you have to use Y-splitters. That way your preamp volume control will control all. Otherwise a mess with control of volume.

I have used three different preamps with my 004 and 005. The Freya+ was my middle pre and is very good for the price. The emphasis is on: for the price. I used it with NOS Chrome Domes. Having tubes somewhere in the system when you are running a solid stage DAC (which is to say, most of them) is great. The Freya+ easily beat out a very good SS preamp. I found, though, that I couldn’t live without a balance control and for this and other reasons went to a much more expensive tubed preamp. It’s all much, much better. The moral of this story is that to hear it at its best you cannot match the Musetec with components appropriate to only a $3000 DAC. In this I agree with @sns . In your place I might consider selling all your pre- stuff and getting something better. But I’m not there and have not heard it all as you have.

As for USB cables. They really do matter and IMO are very system specific. I say first settle on your preamp. AQ Diamond works for a lot of people including @sns. It did not work for me as I wrote earlier. Nor did a custom silver core cable that did fine with the 004. AQ Pearl at 5% of the Diamond price works better here. But it did lose a bit of sparkle/openness that should be there. A change in the interconnect between DAC and preamp is proving just right along with the Pearl. I’ll write about that cable in a bit. So my advice: try interconnect and USB cable. Buy cheap or buy where you can return.

This advice from you and @sns rings true. I believe that if you want to exploit all that a high quality DAC has to offer, you need a top flight quality line stage. I do not believe you can dance around this point. No doubt the Freya , Saga and Topping represent “good value “ and are less expensive. I just don’t feel that you will utilize the full sonic potential using them in place of higher  tier line stage options.

I have had the Freya+, Pre90, Coda 07x and Benchmark LA4. My fav is the LA4 though the 07x has dual XLR outputs and I use one of those to my sub. The CODA preamp sounded the best with the sub. It maybe a gain thing with XLR.

The pre90 does not work well with all amps but when it does, such as with a Benchmark AHB2 or Parasound A21+, it is not a value unit. It is an excellent unit.

I though the Freya+ was good for the money.

I use the 07x and the LA4 with the Musetec 005 and both are exceptional (but different). The 07x is great with my sub.

We tested dozens of USB cables with the opticalRendu (and the entire Sonore Rendu series).  We really liked the IN-AKUSTIK Reference USB 2.0 cable.  That is why it is the only USB cable we carry.  Of course, when we are down to swapping out high end USB cables, it's about personal preference.  Just our two cents for what it's worth.
