Hi Dan I have not heard your exact combo but did own Maggie 20's and did try my Mac 501's on them and it sounded marvelous so I could only imagine with yours. No brightness the you refer to having with your current set-up. If you can get a pair to demo I would recommend you do so but so far anything that I have put the 501's with the sound has been great, bonus no heat from them so they don't heat up a room, the build quality is great along with their looks.
