Hi Dave72, I want you to go and audition the new Krell amplifiers, they would be a very good fit for your JBL speakers, not just any great sounding amp will work!, because of the Hz and Khz specs of your speakers, you need an amplifier that is NOT some wide band bright amplifier, you know, an amp that is 20hz to 100khz, no man, do not do that!, you need a great dynamic, 20hz to 20khz amp, your speakers are already detailed in sound, you need a little warmth, very deep bass slam, very good mids, and alot of air and some sparkle on the top end for an amplifier, this kind of sound will mate well with your JBL speakers, the new Krell amps fit the bill!
