McIntosh MC275 Vacuum Tube Amplifier

Now Showing At Pearl Audio Video – Come in for a Demonstration!

An object of desire cherished by music lovers around the world, the MC275 was designed and engineered in 1961 by McIntosh co-founder Sidney Corderman and the McIntosh Engineering Team. Based upon the extraordinary Unity Coupled Circuit, the MC275 has a lush sound that presents a powerful and detailed soundstage.

The MC275 develops 75 watts per channel into 2, 4 or 8 ohm loads, or 150 watts in bridged mono mode. Both balanced and single ended inputs are supported. The mirror polished stainless steel and black chassis with die cast nameplate is presented here just as it was in the original 1961 model.

Here at Pearl Audio Video we often pair the MC275 with Sonus Faber Venere or Dynaudio speakers for a luscious combination of tube warmth with tremendous detail and vast soundstaging. But don’t let the 75 watts per channel rating fool you, it will even drive the big Maggie 3.7s with aplomb!
