I home auditioned the Mac 6500 and Plinius 8200 Mk2 over a year ago and chose the Mac. Ultimately sold that too as it did not have enough peak power for classical music in my large room.
The Mac was more human, toe-tapping and musical. A female dancer if you will. The Plinus was like the tough guy flexing his muscles... "Look how much I can lift!" Impressive initially but then tiresome. Not edgy, mind you, just too much of a good thing.
I am sure many Plinius fans will rush to its defense, so I have to say, although it is obvious, my opinion only. YMMV.
