Hi-
If you get a chance to audition one, try the Audio Van Alstine OmegaStar DAC. It's a bargain, and sounds exceptionally good. It might not beat what you have, since I haven't been lucky enough to hear a Cary in my system, but the AVA is eminently listenable, and has some of the best lower end dynamics I've heard from a DAC while still maintaing detail & clarity in the top end without a trace of harshness.
Happy Listening!
