The one I really like is the Audionote DAC-5 signature. It sounds extremely smooth and relaxed, but not sluggish and dead. The way it handles woodwinds and string instruments, in particular, is thrilling. I've heard it coupled to both Audionote transports and to 47 Labs Pitracer.
The bad news is that the last time I looked, it was something like $30k.
