IMO the newest version of the 7.5 is not even in the same class as the ARC 3. The 7.5 killed the ARC in my auditioning experiences. There is also a dramatic price difference between these two pieces that is being overlooked here. The ARC 3 is really more on par with the 6.5, both soundwise and pricewise.
At this level though you really can't go wrong with any of these pieces. They are are excellent, and make making a final decision very difficult.
