Has Anyone Auditioned an LKS MH-DA004 DAC?

An unanswerable question.

The LKS has two 50 watt toroidal transformers.  One is for the digital circuits; one for the analog circuits.  The Holospring appears to have one transformer about that size (Is it, in fact?) and one quite a bit smaller.

What would be the advantage of a silver v. a copper transformer of the same power?

In any event, to answer your question I suppose you'd have to buy an LKS and substitute in a silver transformer.

 Can this Dac sound harsh In anyway?
especially in upper mid and lower treble?
Have had a Primare Dac 30 for the last 4 years, a nice dac, just wondering if LKS would be more analog sounding?

The DAC has been in my system for about 2 years. I have been mostly an analog guy. Previous tries at digital didn’t get much listening but this DAC does. My analog system is VPI TNT, AT Art-9, three stage all tube (no SUT, no transistor) phono pre. Rest of the system is solid state. As for SQ I am currently indifferent as between listening to the DAC or to LPs. Since getting the DAC I have accumulated a lot of CD/SACD files (a good many from local libraries) and listen to LPs because they are old friends. SQ from files is better than from silver disks.

The answer to your direct question is the same I would give about my analog system, it depends on your software. It will be revealed, quality, warts and all. The LKS is not a euphonic device. To a very very small extent with the DAC, as I live in a large crowded metro area performance may vary with quality of the electricity and the unit may sound better at certain times. Some have put electricity re-generators in front of this and other DACs.

The problem with buying the LKS DAC is that there are very few of them so it’s hard to get opinions. But as compared to your DAC, it has a much more robust power supply, 2 DAC chips each costing 5 or so times what the DAC chip in your unit costs (though correlation between price and SQ is questionable) and a fully discrete FET analog stage as compared to chip implementation. Anyone getting the LKS should shield the transformers, very easily done.

Anybody know if this DAC support DXD files? 
Thanks!

@suavek,

Through its USB port (but not through its s/pdif) it will support 384K 24/32 bit PCM files. That should cover DXD files, though I have never tried a DXD file myself.
