Driving my 950-7100s into Heresys...no problems here...Heresy mains, Academy center (maybe another Heresy someday) and KSF-S5 rear surrounds (mayby Heresys there too someday for an all Heresy HT)...I think they are great...1st floor I have McIntosh SS and K'Horns...no shrillness from my speakers...
