I can sell you one (brand new, never used) including power supply.
Send me a PM if you are interested.

Looking at my past posts....I think I misrepresented some facts a bit. The Upsampling board does not share a rail with VA on CS4398. However the CS8416 has a single PSU as standard.
I wasnt completely misrepresenting....just a bit.
PSU is still a massive influence on audio performance.

This thread is about the (Gigaworks) CS4398 kit.
As for a tube output stage I do know of a guy that used a tube stage from diyhifisupply and is very happy with it.
how do you make USB input to work? SA=1 and SB=0 right? Then set USB audio as default device?
I just came across this impressive thread and have only zapped through some posts yet. It seems that for best sonics output transformers are preferred here.
I consider integrating this DAC in my new tube pre-amp. Because I don’t need low Zout (no interlink to drive) and the CS4398 has a normal line-level output, is a transformer still the best way to go, or can I tap the signal from the inverting- or non-inverting outputs by a coupling capacitor? Does anyone know the offset voltage at the output of the DAC?

Caps
I find that the best caps such as the Dayton foil sound better than any affordable transformers like the Jensens to block the 2.5V DC and I run with no ultrasonic filter.

Scott, thanks for your reply.
Is the offset voltage on both (+ and -) outputs the same, or are they inverted just like the signal.

Peter
Same
The offset voltage is the same +2.5v on both legs of the output so you can connect a trans primary across them with little to no dc current flowing as long as you don't center tap to ground.

The new "Lars/gigaworks dac" seems to be ready.

An externally hosted image should be here but it was not working when we last tested it.

$320 for that thing is insane....
Even the shipment at $60 is a rip-off.
Here's the Audio-GD NFB 5 with much better design, case, power supply, no OP's.... and the shipment is cheaper as well!
