But I don't require anywhere near that amount of power it is a waste. You also require an electrician to install a 20 amp supply.
Your JBL's would have been fine with the XPA-5 as well. They are super efficient speakers as mine are.
I have a five channel system now if you read the first post when I joined in this thread I had an unfortunate incident with the 5 channel amplifier I purchased.
I now have a stereo amplifier and only require 3 channels but 5 would be acceptable if I ever go to 7.1 surround its already there.
A used Krell is on Ebay right now for the cost of a new XPA-5. and that is just the opening bid.
secret squirrel has me convinced that the 32db is not going to be an issue.
Still, I'd seriously consider the XPR-5.
Yeah, my JBLs are somewhat efficient (91db fronts, but 88db surrounds), and my LC2 center channel speaker, though rated at a high 92db sensitivity, is really a 'power pig' in disguise!
I've never clipped with this amp, but I have driven it pretty hard at times lighting up all the LEDs all the way to the top a bunch of times with dynamic movie soundtracks ('Looper', 'Saving Private Ryan', etc.).
But in any case, the XPA-5 would be fine in your case too, those some have reported a slight 'hiss' with very efficient speakers (due to its 32db gain I'm sure).
Easier to drive the XPAs to full output with an AVR's pre-outs too, since they put out lower voltage.
Good luck with whatever route you go, but please post back here your experiences.
