I had a brand new set up professionally installed in my basement three weeks ago. Here's the gear: 5.1 Setup: Denon AVR-3311CI, Bowers and Wilkins Front: CM9 x2, Center: CMC2 Rear: CCM662 x2, Velodyne SC-1250 with 2x SC-IW subs, Monitor: Sharp LC-52D92U, Blue Ray Denon DBP-2012UDCI, Motorola DCT3416 I cablebox Upon listening for about 10-15 minutes I notice a tense sensation in my ears that builds and builds to become pain and a sensation of fullness or ear popping. I find myself having to gradually increase the volume over time to be able to strain to hear. Once finished watching/listening, the sensation lasts for hours before finally going away. Putting the receiver setup on direct or pure direct helps somewhat but it's still a problem. Engaging Audessey EQ or other EQs makes it worse. It happens at all volumes. I know speakers need to be broken in, but it's been a few weeks and the problem isn't going away. At first it was just me, but now my wife is noticing it too. Any thoughts? I want to talk to the installer from the standpoint of at least knowing a little bit of what I'm dealing with. G.L.
