What is Included: Amplifier, Remote, Manual, Factory packaging Functional Notes: Operational condition of this item is excellent, fully tested and no issues found. Overview Compact yet powerful, the McIntosh MC252 continues a tradition of classic McIntosh amplifier design. Cool and quiet in operation while rewarding to listen to, MC252 is the McIntosh value amplifier. With 250 watts per channel at 0.005% maximum distortion across the entire audio spectrum, the MC252 delivers a tremendous amount of clean power. McIntosh’s exclusive Output Autoformer ensures the amplifier will always deliver full power, without stress, to any type of loudspeaker. Whether the speakers used are 2, 4, or 8-Ohms, McIntosh Autoformers ensure that every bit of power is utilized. Superior, fuse-less short circuit protection is provided by the McIntosh Sentry Monitor circuit. Power Guard, an input/output comparator, responds within 1/1000 of a second to eliminate amplifier clipping. A polished stainless steel chassis, premium glass front panel with fiber-optic / LED frontpanel illumination and True Power Peak Responding Wattmeters lend a look of pure elegance to this powerful amplifier. Features Waveform comparison circuit continuously monitors both input and output signals to avoid clipping while preventing harsh sounding distortion. Fuse-less short-circuit protection circuit disengages the output stage before current exceeds safe operating level – resets automatically. Unique McIntosh Autoformer technology delivers the full rated amplifier output with the least possible distortion into loudspeaker impedances of 2, 4, or 8 Ohms. Swift, accurate Wattmeter response reveals program peaks so staying within the power limits of your loudspeakers is easy. The two 250 watt channels may be combined into a single channel of 500 watts. McIntosh exclusive output autoformers allow this 500 watts to be delivered into 1, 2, 4, 8, or 16 Ohm speakers.

JKent Posted September 20, 2016 Report Share Posted September 20, 2016 11 minutes ago, DavidHi said: These are very heavy and local pickup preferred hmmmmm.... Aside from the fact that those are the antithesis of "classic New England" speakers, no location for p/u and no mention of price. I'll pass.

Klipschornman Posted September 27, 2016 Report Share Posted September 27, 2016 Agreed... Since I have been dumping Khorns at $900 each, I would offer $50 to $200 each, and that would be generous. So if the original seller drops the price by a factor of ten, they might find a buyer. Just my humble opinion. Link to comment Share on other sites More sharing options...
