I can't speak for McIntosh, but what ever amp you decide on make sure it's at least 200 watts per channel high current. I have N802's. Started with a 155 watt per channel crown DC300A. They sounded okay. I then Bi amped them with two crowns. That made them sing at approx 300 per speakers. Couldn't leave well enough alone so I went to a PSA pushing 400 per speaker. That really brought them to life.I spoke to a B&W engineer there feelings is the more clean power you give them the better.
Happy listening
