Have transports improved for Redbook CD playback?

Celander,
I have an Exemplar modded Oppo 83 that I play SACDs on. I couldn’t run it to my Schiit Gumby because it has no 2 channel output other than the rca, as I recall.  Check your Oppo and the DAC; I’m not sure you can run the Oppo to it.
Oppo DACs seem to be pretty good. I think my Mac changer through the Gumby sounds a bit better than a Red Book on the Oppo, myself. 

You might take a look at the Bryston BCD-3. I love mine. RedBook CDs only. No SACD.  Superb DAC and OEM transport. No jitter.

Just a thought

I'll agree. That was my input, not the manufacturer's.  

The BCD-3 has only 1 master clock  that controls both the transport and DAC rather than the DAC slaving to the usually inferior transport clock.
