Any one try pa amplifiers for home stereo?

Hi, I was looking for info from anyone that had sorted through some of the offerings from QSC, Peavey, Hafler, Crown, and the alike for sound and compatability with home systems. I am looking to drive Infinity Kappa 9's. Dependability and cost seem interesting. I like a slightly warm sound with bloom and am midway through a Foreplay tube preamp build, Which should allow easy mods to selecting output voltages.
Thanks for your opinions.
