I just heard a pair of the latest JL7s and was blown away. Apparently CAT now has a website too, catamps.com. Welcome to the 21st century lolWhile SS amp shopping for my TAD E1, ended picking up a pair of Convergent Audio Technology JL7. Still have the ARC REF250SE ... triode vs push pull, different sound and very enjoyable. Both high current amps should be able to drive new speakers when I upgrade .
