Crown PSA-2 power amp. 275w/channel into 8 ohms, 460w into 4 ohms, 700w into 2 ohms and 915w into 8 ohm mono in bridge mode. this amp is big, heavy and will drive the living bejesus out of any speaker you care to power with it. its in decent shape, but could probably use a servicing.
longshot, but i also have the 5.1 upgrade kit for the first generation Bluesky Mediadesk monitor set. This is just the power amp, 3 satellite speakers and the volume control knob. this stuff is all in excellent condition and was babied since day 1
