I'm not familiar with McIntosh electronics but I use a VAC preamp and amp with the same output on my N802's and I love the sound, plenty of detail without the glare. I didn't like the soundstage when bi-wired so I single wire with Audio Magic and use the B&W supplied jumpers. If you purchase the B&W's and decide to spike them I have some special things for you to try. I think you will end up with a setup you really like. You didn't mention music tastes. I listen to mostly 60's jazz and the system is voiced with that in mind.
