Am replacing a system in a home garage following a flood. Former gear was a pair of Rotel RB-850 amps and a Rotel preamp/tuner, and the setup drove four tower speakers well enough that an outdoor audio system was unnecessary. I'd like to replace what was lost -- and rely only on one pair of speakers, Boston Acoustics T-830 (8 ohm 3ways). And still get ample sound loud but quality sound when not pushed hard. Budget is $200 to $400; used gear, not new, please. Beyond that, I'm open to suggestions. An outdated home theater receiver marked down huge because it's unwanted? More vintage gear like sansui? Something simple like NAD? Thank you in advance for any recommendations. C.
