McIntosh range
MC257
The McIntosh MC257 is a 7-channel power amplifier intended for a coherent multichannel cinema rack where channel matching and installation efficiency matter.
Where it fits best
Premium seven-channel rooms where equal 4Ω/8Ω rated output, protection and visible McIntosh presentation are priorities.
What to pay attention to
The 250 W figure applies when using the three front channels, not all seven. Account for chassis size, weight and display visibility.
