Just nailed my DDDAC together and tested on my bench supply. So far so good.
I've measured 2.2V output +ve to ground. 0.00V +ve to -ve outputs. It may be a daft question but why can't I use a single ended output on the +ve to -ve and forget the dc blocking caps?

Thanks! It's a Modushop Galaxy Magiorato GX388, the frontpanel is from Schaeffer AG.
They are now processing the same frontpanel with my customer provided 10 MM Alu front from Modushop.

So that will be even nicer, and necessary because when I was drilling and tapping a blind hole at the back to hold the LED-PCB, I almost drilled through ..... and now it shows a big bulge

Default Works

Deep breath and plug it in.
I forgot that the SBT needs the USB output to be enabled
Try again

This is just a lash up to test it. I'm powering it with a couple of cheap ebay sourced Chinese power supplies, a pair of caps from my parts box and mounted on a plank of wood. Hardly hifi is it. Yes it is.

I built this because I wanted to play hirez files and my Audio Synthesis Dax2 is 16/44.1 only. I've been listening to some serious kit from Linn, Naim and Audiolab and found nothing that made me want to part with the AS. Already this is easily the equal of the AS after 1hr of playing.
Now that I know it's OK I'll spend some time and effort to finish it to a standard it obviously deserves. Problem is that I'm listening instead of working

Next question is cinemags or Sowter, anyone heard both?

Doede you're the man.

thanks for the flowers good to have some positive feedback! keeps me going

on the question, why not use just pos and neg terminal to avoid capacitors...
it might work, IF the amplifier which follows is isolated from ground. otherwise you will add the complete ground of your house to one of the outputs of the DAC. it might work fine indeed, but it might hum as hell.....

why not try it if you think the rest of the chain can float

I wired the dac using the balanced phases into my preamp with no cap. No hum, higher output and slightly better sounds. All good, no drawbacks as far as I can tell, but my system is dc blocked pre to power

2w shinkoh tantalum resistors for IV + custom sowters from Doede (1:1 and 1:0.5 windings) = very nice!

The sowters have lowered the noise floor producing a blacker background. I can hear further into the music. Small naunces and delineation of notes/voice seem more fleshed out and essier to pick. The music seems to also have greater sense of purity and presence. Improvement in 3d soundstage clairty and resolution as well.

Coupling caps I have tried are wonder dynamicaps, jensen copper paper tube, ampohms, auricaps and duelund cast coppers. Duelunds being the most fluid, natural sounding while still having excellent resolution out of the various caps.

Sowters bring further improvement than the duelunds.

All IMO of course!

MERRY CHRISTMAS ALL and thank you again Doede! <3
