Wadia 321 DAC VS. PS Audio Perfectwave II DAC. Any thoughts ?

The 321 don’t do DSD.
They are both old.
DACs have gotten better/$.

Wadia is gone, so forget about any service. The 321 was not even a “real” Wadia. The age of both makes me think you should be looking at more current pieces.

Wadia is not gone. Check with McIntosh.

@RSA
Wadia went through some ownership changes and McIntosh eventually took it over as part of its MBO. While the website is still up, it is for service. The products are no longer being manufactured.
