Consider a used Mark Levinson 331 power amp which outputs 100wpc @ 8 ohms and 200wpc @ 4 ohms. You should be able to find one in excellent condition for about $2200. Use a bi-wire instead of a single wire configuration to get smoother highs and cleaner midrange.
I find the Mark Levinson 331 musical and the Bryston 7B-ST theatrical (more Hi-Fi & less musical).
