I own 3 KLIPSCH systems. A 2-ch Ki-396 Master bedroom setup / a 6.2 downstairs RF7iii Theater setup / a 5.1 Klipsch Pro Jubilee Surround DVD-Audio setup , Theater upstairs.
Every single amp used in those rigs are Carver Pro ZR1600's , all bridged in Mono. So I'm using 18 of ZR1600's, and have 2 more as backups, 20 total ! Also for my Jubilee Sub duty's I use the mammoth Crown macro-tech 3600vz , run thru a Danley TH50.
I used to have Tube amps, ...never satisfied...then I finally found an Pro Solid State amp that dominated in clarity / dynamics and power to boot ... everything I hadever ever wished for in a Pro amp. ...and Rack Mountable. (Pic below is the JUBILEE 5.1 amp rack, using 10 Carver ZR1600s bridged in Mono...to Bi-Amp all 5 Jubilees.)
