Experience with this DIY DAC ?

[squatt3r]

who is still selling this DAC? its no longer listed in gigawork's ebay page

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

thanks Ryssen!

Data, how are you getting on?

 

[gsa]

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.

Anybody using a tube IV stage ??

 

[Adrculda]

Instead of the Op Amps I mean....

Also...
Input on this DAC would be appreciated

 

[Extreme_Boky]

395 pages worth of input is not enough?

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.

 

[squatt3r]

how do you make USB input to work? SA=1 and SB=0 right? Then set USB audio as default device?

 

[squatt3r]

finally got this thing to work

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?

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.

Same

Scott, thanks for your reply.

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!

any recommended Op-amp that can give more bass?
