I would recommend the CAL-2500. Read the Stereophile review and the Widescreen review. It uses a heavy duty transport and the electronics are heavily regulated and isolated. I bought it to just to drive my Reimyo DAP-777, because it has a balanced digital output. There is someone who bought up a lot of the stock and is selling them for $830 a piece. That's what I bought, brand new in the box.
