This is a review and detailed measurements of the Musetec Audio (LKS Audio) MH-DA005 ES9038 based stereo DAC. It was kindly purchased new and drop shipped to me. It costs US $3,299.
At 12 Kg/26 pounds, this is one of the heaviest DACs I have tested. Fit and finish is excellent as you can see in the above picture. That carries to the chunky metal remote:
When I plugged the unit in, Windows did not load the class driver for it which means it is not class compliant. I could not find a driver online but a flash drive as shown above comes with an ASIO driver. The internal USB interface is the common but old Amanero. Driver installed but the ASIO driver would not function. The remote was not functional either. I saw a screw driver in the box which I assume is to open its back to put in batteries. What a pain.
When I powered the unit, it started to count down tell me to wait! I glanced at the main board and it seems to have a bunch of supercaps or batteries in that that it must be charging. Anyway, I waited the two minutes for it to get ready.
Musetec MH-DA005 Measurements
I couldn't believe these results. Company spec is 10x lower distortion:
I changed inputs and measured RCA output:
Going with this, performance is unacceptable at any price level these days let alone wht MH-DA005 costs:
I suspected the output stage may be saturating so ran a sweep:
That is it. We are now very close to rated spec (110 dB vs 114 dB spec) but we can only get there at 1.5 volt output. This is bad.
News gets worse with IMD two-tones:
So we not only have output saturation we saw before, but mother of all "ESS DAC IMD hump!" At lower outputs performance drops to that of a $9 phone dongle!
Not all news is bad. Dynamic range for example is excellent:
Linearity is perfect:
Just when you settle in, here comes the jitter test:
There is a DPLL bandwidth setting but that could help internally generated noise sources above. But even if they do, none of the settings should be this bad.
Without the remote working, I could not change filters. Fortunately the default one is what you expect:
Multitone test shows rising distortion with frequency which is again disappointing:
This in turn shows up in THD+N vs frequency:
Conclusions
So easy to fall in the trap of going by looks, price and written specs (as opposed to proper measurements). While doing a few things right, there is a lot wrong with design of MH-DA005. They have an excellent core as far as DAC chip is concerned, but they poorly implement the companion circuits. Instead of focusing to get the basics right, focus seems to be elsewhere (battery bank and such). A shame since the packaging is very nice.
I cannot recommend the Musetec Audio (LKS Audio) MH-DA005. If someone thinks this sample is broken, then get the company to produce the above measurements and I will happy to revisit.
