Add a digital coax in /out tube pre-amp

Is it possible to have someone take my older pre-amp that only has analog RCA and add input and output digital coax?


Why?  What’s the point?  Why would you even do that?  Just get a DAC and feed it into the analog inputs in your preamp.  I don’t get this at all. 

who, what, where, when, WHY?

What are you trying to do?

How would you select that input?

Tape Loop. Perhaps a small external box, run thru the Tape Loop?

SPDIF to and from an old preamp?


Get a DAC with enough inputs for your needs (remote controlled if you know what’s good for you) and plug its analog output into an aux input on the preamp

Or get modern an buy an all-in-one like an A20, only  $22K.
