Hi All
Well that's the AK4396 Dac up and running
Still in standard mode and still needs a case I have ran it for the last 22 hour continues and it just gets better its power by two rapid TXs one 0-12-0-12 30VA and one 0-9-0-9volt 30VA but with just one side 0.9volt
One strange think thou about 20 minutes in from fire up it stop no sound and all the LED's were locked on this happened one time only well so far switching off and on again fixed this any ideas to what happened
I have also ordered new better op amp LM4562NA to try

I think the reciever chip sometimes gets confused and locks up.

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..

Yep nine is still going strong
All I have doing to it to date is a this FET Buffer I suppose I should try a valve buffer of some sort but it sounds great with the FET one
