Thanks for the information. I found the Hosa CDL-313, which I think you are talking about. Hosa says that it supports 24-bit/96 kHz S/PDIF audio. I assume that would be the limit of the output of the uh-7000 when converting to s/pdif.
I have posted a question to Tascam concerning using the uh-7000 with the Tascam us-428. Maybe they or someone here could tell me if the us-428 can handle this resolution that is higher than it's native resolution.
I would need to know if I will lose the additional resolution before buying an additional device like this one.
Sorry to be so ignorant, but will the RCA, s/pdif cables need to be special digital (coaxial) design?
