McIntosh has unveiled a new seven-channel home cinema power amplifier. The MC257, a direct replacement for the outgoing MC207, is the first to feature McIntosh’s new TripleView Power Output Meter which independently indicates the real-time power reading of the amp’s three front channels.

The 38 cm TripleView meter design is an update of the three individual meters found on the previous model. The chassis is stainless-steel. And yes, the brand’s familiar blue lighting can be turned off in a dark room environment.

The MC257 can be used to power a seven-channel home cinema, or paired with either McIntosh’s MI128 eight-channel or MI254 four-channel digital amplifiers in home cinemas that have more than seven channels. Alternatively it can drive a five channel system, and a separate stereo second audio zone.

Power output is rated at 250 watts per channel across the front left, centre and right channels, dropping to 200 watts when all seven channels are driven. McIntosh Dynamic Power Manager (DPM) technology delivers the full 200/250 watts regardless of whether 4- or 8-ohm speakers are used.

The amplifier also boasts a 94 per cent increase in dynamic headroom (from 1.7dB to 3.3dB) over its predecessor, as well as a low-frequency performance.

Beneath the hood are five McIntosh Monogrammed Heatsinks which are connected to advanced high-current output transistors to silently cool the amplifier; there are no noisy cooling fans on-board.

Around the back are gold-plated speaker terminals Both balanced and unbalanced inputs are included to connect the MC257 to a home cinema processor. Power Guard prevents potential speaker damage, caused by clipping and over-driving, while Sentry Monitor technology protects against short circuits. 


The MC257 retails for £12,995, with shipping beginning October. Distribution is via Jordan Acoustics.
