Well I feel very comfortable comparing these two units. I have given my comments on the PT unit on other threads and there is no point in belaboring my impressions. The Bel Canto is MUCH more like music than the P-3a although the P-3a is on the right track so far as resolution and dynamics. Tonally it is all wrong and really doesn't compare. DO NOT take my word for it, listen for yourself, it is a no brainer. The Bel Canto is MUSICAL. I got listener fatigue in short order with the PT unit and sent it back. PT DOES give a 30 day no questions asked in home trial period so there really is no reason not to listen for yourself. The Bel Canto isn't as successful as it is for no reason. It is a great product at a real world price. Good luck.
