i have had my eye on the signature 8 from paradigm for some time, read the reviews, checked the web, & listened to the demos at the dealer 10+ times, powered by BK amp 125.2, and while i liked the sound & the detail, i found myself almost bored at the dealer listening to them. so this weekend i took them home for a demo. my system is an avm 30, krell kav 2250 for the fronts, cary cinema 5 for the rest. i tried it with both the krell & the cary & it sounded fantastic, the detail remained but now the sound had body as well. i'm looking at the 100's to use as centers & for surrounds & will eventually demo those at home as well (don't hold your breath it's going to be awhile). the paradigm's are more difficult to drive than my klipsch rf-7, and need as much quality amplification you can through at them. from experience i would recommend krell or cary audio. cary makes 2, 3 & 5 channel amps from about 2000-2500 for the 2 channel msrp, & a good dealer should knock a good amount off that. months ago i did hear the 100's with a want to say a krell showcase amp & the sound caught my attention, that's what caused me to take a look at the sig 8.
