gonk: Thanks for the reply I had them set at a +6. Have you herd that the B&W's are hard to drive? Like I stated the old Yamaha seemed like it had more punch. Not as clean by any means !! I did hear a huge difference in the clarity? I had to have my 14 year old sit down and confirm myself. I was thinking of going to the 7500 whats your thought? New Shooter
