I don't know the specs, but I have listened to it in an all Mac system. Very smooth and musical. But - the transport is noisy (too noisy for my room and listening position) and there have been problems reading some CD's. The later problem may be resolved with firmware updates. The noise may not bother you if you sit far enough away from the unit or place it in a cabinet. Otherwise it sounds very nice. I would buy it if it were not for the noisy transport.
