Anyone using McIntosh with Vandersteen Quatros

Fogwell123, I think you have excellent equipment that just needs a bity of tweaking within the room perhaps, and bass traps certainly made an improvement in my room. I would look to those things before having any concern between the amp and speakers - you have a very solid foundation for a great sounding system.

Macs tend to be on the warmer side of neutral as do the Vandersteens. That may make too much warmth for me.

You really need to make sure you nailed the -3db down point
with the 1000 hz /100 hz test tone with your volt meter reading a 1 volt for 1000hz and .707 at 100 HZ when you are there its in the Owners manual
I have found many amps are not what the Manual says they are and your whole tune up of the speakers and correct x over setting is affected by this.
you can reach me at 973 239 1799 if you need help
you should have a great match when you get the X over and room dialed in.
Cheers Johnnyr

Thanks to everyone for this. It sounds like more work on setup is in-order and the vender's suggestion for bass traps may be a good one. Good to know I may be on the right track after all. Keep the reply's coming.
