Hi All

I think the reciever chip sometimes gets confused and locks up.
Whenever an honest man discovers that he's mistaken, he will either cease to be mistaken or he will cease to be honest.

i have exactly this dac board, although mine came with sanyo power supply caps
i thought it sounded pretty good.
these only cost just over a tenner delivered from Taobao (chinese ebay) which makes it bargain of the century!
i was planning some upgrades, maybe better op-amp and coupling caps.
i think the Spdif input circuit could also be better, with a pulse transformer added etc..
