Given Tom's request for amplifier reviews, this is what Martin Colloms has rated various power amplifiers at using his scoring system. I have put them in ascending order of merit. I just thought in was an interesting read. I wouldn't take it too seriously. I know I don't agree with all the rankings - far from it in some cases!
OK so it's no indicator of how well each design will cope with Logan's, but you can rest assured that the powerful ones will all cope pretty well, I'd expect.
