I owned a pair of 805's and 804's that I upgraded too. Tried all kinds of amps, Bryston, Levinson, Audio Research, Proceed, Anthem, Magnum Dynalab, Rotel, and preferred the Musical Fidelity gear. Those big 250watt mono's and there A3cr preamp, did the trick with Transparent cable. Nice and round and plump and smooth. The Bryston was exciting but over the top. The magnum 308 receiver was very nice but not enough oomph! The rest were either too boring and nice or much too expensive like the levinson intergraded and the powerful tube gear. Maybe Sim Audio since I understand they made the gain stages of the receiver. Never heard it though. I always thought of the speakers as pretentious sounding and demanding of rather polite and refined sounding stuff. That my story and I’m sticking to it.
