Can read it both ways, he should have put "would be" between but & a .

Wolfson WM8740 voltage output dac has it's own internal I/V opamp convertor, can't be bypassed either, bummer no using the Zapfilter in current input mode which is what it shines at. I prefer current output dacs more room to improve on.

Cheers George

Hi George, why do you think that internal I/V is bad?

From what I've been told they're usually just your plain Jane NE-5532 or similar, and there's nothing you can do about it as far as doing something better. Like a proper discrete Transimpedance I/V amp, this is why I like current output dacs or Voltage output but with a bypass pin built in for the internal I/V opamp like the PCM56P or the PCM63 has and a host of others.
Cheers George

Sorry, I was talking about my previously modded unit George.


Agreed on the Zapfilter in current mode.

George, its easy to see he meant modifcation and not stock unit! i notice an increase in noise when the xlr outputs are used for rca inputs, but through the single ended outs there is no noise, this is when volume control on headphone amp is turned all the way up with the source pause. cheers

Hello,

I was also searching the net, but you are absolutely right, not much to be found. I really don't now why cause everybody say its already pretty decent as stock unit, and sure has the good potential for mods - especially when you need both Balanced and RCA.

I don't think that the guy on ebay selling that supply is gonna reveal what he uses, only if someone bought it and is willing to open it
