Using soekris dac myself together with dcg-3. Works like a charm. The dac has a unreleased potential with regards to digital filters IMO.
With good filters the dac is extremely good.
However:

volume controll is made in PCM. You have to leave pure DSD path. There for I would like to have the controll within the DCG-3.
Did that make sense?

True, its all in the filter codes. It's a chameleon.

The DAMs, being R-2R devices, need to convert DSD to PCM to make sound. Disabling the digital volume control will not help with that. There can be no "pure DSD path" with R-2R dacs.

Just saw your nice blog, DimDim... are you currently developing a nice pcb for Salas Shunt Reg 1.2R? Quite interesting.

Received my chassis from Diyaudio a bit earlier than expected. It is rather large and has plenty of room. The rear panel is cut for IEC plug, the part I have would work, screw hole spacing is fine, but out line of part doesnt quite cover the entire hole, leaving some small corners exposed. The part for the precut power amp size Chassis from Diyaudio store contemplates a different sized part, too large as it also holds the fusing.

Is there a plug everyones been using that fits this cutout and includes switching as well?
I am looking at Mouser and Digikey as I type this...Thanks in advance to those who have located this part.

I know, after searching myself blind, I have come to the conclusion that there is not one that small that has a switch. I found some with a fuse, but none with switch. So, one more hole must be drilled. It would be nice if the store made it large enough to fit a switched one but thus is life. I really like the way they do the power amp size one with the built in switch.

Once the power inlet is done and the power supply wiring to it done, can the power supply be tested with no load and not yet connected to the amp board?
