I bought a Legacy 4/3/2 (manufactured by Coda) for under $1k. I use it in 2 channel mode which operates in class A mode up to about 25 wpc then gracefully transitions to class A/B up to 450 wpc into 4 ohms. It sounds as good as anything I've ever heard. The class A mode provides low distortion and wonderful detail at low volume while the 450 watts frees the sound from the speakers. Nothing seems to come directly from my speakers (Infinity Prelude MTS) unless the source was recorded that way. I've experimented with the 4 channel mode which provides 225 wpc into 4 ohms and you can definitely tell the difference, even at moderate levels. Power is good.
