Hi Sutts,
I used to own a pair if Infinity IRS Beta speakers. I went through Krell, Bryston, etc. for the (8) 12" woofers. I was moving amps around and hooked up a QSC M3000a as a temporary amp. It blew away the Krell KSA-150 and Bryston 4B NRB. The bass was solid to 20 Hz and slam was much better. Best of all, the amp had volume controls and cost less than $1000 NEW!
The QSC PLX 3002 is now available with a switching power supply, 3000 W @ 8 ohms bridged, runs cool, weighs 21# and takes 2 rack spaces. Still around $1000. If you are interested, you might check with a local pro musicians store. They may let you demo one. QSC also makes lower wattage versions with the same power supply.
Good Luck!!!
