Help, I am catching upgrade-itis(?) fever...

Three weeks ago, I upgraded my HT from Pioneer Elite VSX-07TX to 950/7100 combo. My main speakers are Paradigm Studio 60's. I've been happy with the sound of the new system.

I am in the process of upgrading the surrounds and add a rear center (See "Wife prefers small speakers" post)...
and last Tuesday, UPS showed up with a super heavy box containing the 755. I must have ordered it while sleeping...So much for setting a 2K budget.

Any way, in stereo mode with the 755 and the Paradigm, the music seems bright and harsh, with heavy emphasis in the midrange frequencies (CD's listened to: Sarah Brightman, Enigma, Fleetwood Mac, Santana...) The Elite and 7100 did not sound this way at all.

Is break-in needed for the 755? I have left the 755 on 24 hrs last 2 days, no changes heard.

Does it sound this way with your 750/755/770+Paradigm?

Am I missing any settings on the 950? Re-calibrate?

Continue on with the upgrade fever, if I decide to keep the 755, hello M200?
