DDDAC its good hifi i heard 2 of them i would not buy one its still artificial
the quality of a DAC - all that we tested so far - finally may not be judged simply by the DAC itself... this is only half of the rent...
the other half (not only to my ears 50%) is defined by the corresponding power supply...
we have been through various sorts of power supply with all kinds of "strength" regarding power and weight, i.e. normal car batteries, some ten kg, lorry batteries up to 40 kg, "normal", i.e. "small" power supplies, and in the end (so far) controlled power supplies up to 20 kg...
and we tested out the different kinds of Doede's own power supplies, and even Jean Hiraga's new construction after he had become aware that batteries - although good - no longer have any chance... to illustrate the point, at the end of last year he came around the corner with something like this, a 26,5 kg battery:
but he quit caring for batteries immediately after having listened to the different (controlled) power supplies that we had already here with us in direct comparison, and because of the great differences in "generating" sound with these power supplies he constructed one for his own purposes, and yes, this was good, but had no chance in reaching our level...
but things go further: within this context there have been developed superb power supplies and discussed on the DIY-site, so, you might want to read more over there, claiming to meanwhile have come to even better results... and these results come from people whose skills I had the pleasure to get to know of and appreciate in april this year, and from these results I have no doubt that it is like that, but I have not yet listened to that personally...
so, if you should have the possibility, I only can propose to you: have another try, not only for any DDDAC but for the one(s) you use personally, it is very very very well worth it...
and by the way, to my presumption - I see nobody theoretically neither practically caring for this topic at all: this should be valid for ADC as well...
...and within another step - what as far as I can see neither anybody as well is talking about - for the different power supplies 3,3, 5 and 12 Volt within PC and MAC...
there is still a lot to try out and to discover, and I will be glad to read about any positive contribution regarding that/these matters...
