Gary, great news...I was expecting that you would really like the CAT JL5. I am sure that this amp will be a great match to your Gamut's. Like you said, you match the amp to the speaker...and not the speaker to the amp. CAT is such a great piece of gear...as you know, I am a very BIG fan.
Oh, only drawback is now you have to think about the CAT preamp...;0)
