Afraid I can't offer much in the way of comparitive input as I've not heard the Bryston or Parasound, but I am a very happy owner of a McCormack DNA 125. I have a Denon 4800 AV Receiver in use as a preamp and to drive my center and rear speaker. all the speakers are Mirage with OM 6's in the front pair to a Frx 12 sub. The mcCormack may not be as easy to audition but do give it a try. also see the current, december, issue of Stereophile. good luck.
