This is the outstanding 450 watt per channel stereo power amp (into 8 ohms) from the one and only McIntosh! Solid state amp and enough power to handle just about any speaker ever made, even very inefficient ones like Magnepan, Infinity Kappas, Apogee and Quad! Typical rock solid, bulletproof construction from Mac means you'll be enjoying this amp for decades to come with few if any problems! What other brand amp can you short out the speaker wires by accident or intentionally and the amp is not bothered one bit! Most other brands would go up in smoke! This one is a one owner machine in excellent condition with all of the items it came with from the factory. Ck out my feedback and buy with confidence! Paypal adds 3%. Can deliver if in the Seattle/Tacoma/Portland vicinity. NEW, LOWER PRICE FOR QUICK SALE!!
