examining this dac designs I see

cs4397 and cs8416 - two pcbs - one ne5532
cs4397 and cs8416 - one pcb - two ne5532
cs4398 and dir9001 - one pcb - two ne5532

which of the 3 is best
I think first - It Is claimed to do 192 kHz and you can do mods - change tha caps
the ones with dir 9001 got lesser jitter but no 192 kHz

what are your choices

Actually, I think that the best is to buy the one with the upsampling board and USB and adding a digital transformer at the spdif input.

If you don't like upsampling, you can use it without the upsampling board

I agree completely, I didn't think I would like upsampling, but I was wrong. YMMV

Default Edcor

I didn't get the 600:600

I got the 10k:15k for experimental purposes.

I haven't had time to wire it in. I will try tonight. I know it will take several days to break in so I'll report sometime next week.

could any experienced person explain the role of the audio transformer used in output stage and also what has to be the type 1:1 600/600 or whatever and why

Sorry for the silly questions.

In legarem's diagram in post #418, the black wire is connected to the ground connection. Is that the analog ground of the DAC?

http://www.diyaudio.com/forums/attac...amp=1241223954

Also, on the same diagram, is the type of capacitor across the transformer primaries important (0.0047uF)?

Those aren't silly questions.

The caps should be good quality polypropylene film.

The grounding issue is best answered by legarem, I wouldn't think it wise to defeat the isolation provided by the transformer by connecting one side of the secondary to the audio ground.
