Muse Mini DIR9001+4X TDA1543 parallel connection NOS DAC. USD 63 shipped.
I did a blind test assisted by a friend - I preferred it 16 of 18 times to my six months old $2500 Dac. And, no - it wasn't less detailed. Slightly less bright. How come it is so cheap? It is a cheap design. Lucky shot. Whatever. Just do not use the switch too much when power is on - it gets very confused if you do that :-) And it won't do super duper high res files, I believe. But who cares - when such files are readily available - there are hotter designs to buy than the dacs of today.
