Which DAC is better?

829yn, I have never heard any of the dacs you list and feel that even USB2 is short of SP Dif and certainly short of FW. As Audiojan says only you can make the judgment. Digital is moving ahead so rapidly, that anything you buy today will be obsolete tomorrow.

I am presently using an Exemplar Audio tube dac that is better than my old Weiss Dac202, but soon I will be getting a FW input dac that runs in native DSD. But it really is a pro dac from Empirical Audio Legacy.

I don't know if I agree that "digital is moving so rapidly that anything you buy today will be obsolete tomorrow"... Computer audio (Hi-Rez) and streaming is moving along pretty quick, but except for that.. not that much is happening. And what is happening is not always for the better. Higher sample rates, more circuits, etc. doesn't necessarily make it sound better... different, yes, but not always better...

I just took a major step backwards in technology... Non-oversampling DAC based upon a chip that is really old, no op-amps, but a tube output instead... And the sound is better than I've ever heard from any digital!

Audiojan,
I like your thinking, can you share with us the name of the "old school" dac you chose?
