Any time a recommendation for a high powered tube amp to power a pair of speakers is requested on Audiogon, someone will generally mention the CAT amps. Even the stereo version is enormously powerful and features output transformers that alone weigh as much as the average tube amp.
Most high powered tube amps don't sound very good, and virtually none can properly drive speakers featuring low impedances in the bass frequencies. The CAT amps sound superb and can drive speakers that no other production tube amp can drive (not that the C4's are ferociously difficult to drive, but they do like linear power).
