Mini Maggie System hurts to listen to

I went to a local audio dealer to audition different speakers for a home office. I listened to the mini-maggie system extensively, loved it, and brought it home. Unfortunately at home they are causing something I've never experienced before. After listening to them I feel a clogged sensation in my ears and an almost reflexive cringing at higher frequency sounds. I've put in the included tweeter resistor which helped slightly but not enough. Listening levels are low. At the dealer the maggies had a lot more space behind them then they do here. They are being powered by a Peachtree Inova. Some recordings are worse than others but almost all cause this with time. Sources are digital and vinyl. ~80 hours on the speakers. Any thoughts?
