B&W 803 D3 speakers - which amp?

I have read one or two comments in the past that say the McIntosh multi-channel amps aren't that good, but I take that with a grain of salt.  I don't think you will get any major difference in sound, but the larger MC462 will likely have better bass control and heft.

Not sure what the budget is for this, but I have 803's and they want to be overdriven in my opinion so you are light on the power. side for my taste...    Unfort Big boy McIntosh power gets up there in cost.  Anthem has a new 400x2 that's really impressive.   I have 2 of those new Meridian amps mono blocked to mine and they are purely amazing.  B&W want more power ;)   Hope that helps 

Thanks for all the info...I'm not against spending the money on the MC462 if it's really going to help with 2 channel sound.  I'm just not sure how much difference a 7 channel 200 watt amp vs a 2 channel 450 watt amp is going to make...if it really helps with "bass control and heft" then it may be worth the investment.  Thanks again.

IMHO the 452 will make a HUGE dif in the dynamics and bass even if the volume isn't loud....   its shouldn't be hard to find a dealer that has 452 and 803's on display  both pretty common together at least around the NYC and tristate where I am.  If you are in the NY/NJ area let me know and can prob help
