I heard an older P3 with a Pass 30 watt amp years ago, and it was a truly incredible sounding system. Only other time I've heard Harbeths was C7s w/ a Belles 150, which didn't sound as good. This was surprising, esp. since I had used a Belles amp w/ Spendor LS 3/5s successfully, so I think it must have been the room, cables, source etc. I'm thinking of trying Harbeths myself, after owing a number of Spendors (among others). I just hope they work w/ my VAC. Good luck,
