Summary: These are fantastic speakers and I would buy them again given the same options. They perform extremely well in an excellent, well treated, room. They don't shine as brightly if the room and placement aren't ideal. The easiest thing to lose is their low end impact. I don't have an ideal and well treated room, so I supplement them with a little Martin Logan Dynamo 700.
Summary: The sound of wu wu...........too long bass tail. I believe that was due to the damping factor of the amp, proveded your space is large enough. My opinion only. I did try before by using different amps and got this experience. Big changed. I heard the PMC once, sure that they are good speakers but a little bit over price.
