His newest FirstWatt, the F8 power amplifier, is excellent. Paired with a Van Alstine Transcendence RB 10 tube preamp, the sound is realistic without calling attention to itself ("see how vividly there I am?!"). Of course, your speakers must be compatible with the power amp.
The 25 and 60 are both excellent amplifiers and Pass's build quality is right up there with the very best. The sound is extremely musical and refined timbrally. They are not the last word in "slam" but are hard to beat in their price range in other respects.
