high quality transports

I'd suggest picking up a used Sony SCD-1 for $2500. You can feed the S/PDIF output to your DAC for "RedBook" discs, and connect the analog outputs to your preamplifier for SACD discs.

It really is a great transport!

I have been using the Theta Carmen II, which makes a great transport

Gthrush 1, I like your idea of using a SACD as a transport and having the flexability to use it for both. I will look into this idea.

I second the Theta Carmen II suggestion. It's the best I've heard.

Check out the Audio Note CD2. It goes for $3300 new, but can be picked up used for under $2000. I liked it better than a Levinson 37, Theta Carmen, and Wadia. Great midrange and soundstage with a natural/organic feel to it. Slightly less bass than the others but not at all objectional--PRAT is well maintained. Highly recommended.
