Mcintosh in "The Departed"

So, I'm watching the Departed for like the 4th time I think, I've noticed it before but this time I looked close, Matt Damon's character has a stack of 4 Mcintosh components.

I could make out two of them, an integrated amp, the MA6500 and an Audio Video Player, the MVP861 and a pair of Sennheiser headphones.

Couldn't make out any speakers but there was some audio, they were well placed......
