theta casablanca 3 audiophile qlty stereo sound?

Depends on your definition of "high end" stereo sound. This is a pricey pre/pro and my experience with pre/pro (in this general range, ie. pretty expensive) is that they can do a very admiral job with 2-channel, but not to the degree that a good to very good 2-channel preamp can do. This being said, I am strongly considering selling my existing (very good) preamp and sticking with the direct pass through analog preamp in my pre/pro (which is a new Krell HTS 7.1 which takes its preamp design from the Krell KCT - the reason I bought it in the first place). I did find after buying it, that it was not quite to the level of a good 2-channel preamp, but have now decided that it is, hopefully, good enough for me.

Theta offers three different levels of DAC's. Check out their web site for details. I've used the CB3 with their top of the line DAC's for years. This is one of the few Prepro's that can pull off sounding excellent in two channel. Just make sure you go with the higher end DAC's. Might also want to looking into a prepro with a Theater pass thru allowing for a seperate higher end 2ch Dac/preamp for your music. Just a thought.

isnt DAC is for CDP? Does theta built in DAC card only benefit to CD?
