I've heard the AIII many times (a friend had a pair back in the day), and like it a lot. I think that the AIII is an iconic design, but....
The one thing I've never heard from them is much in the way "depth". When set up properly, the imaging is very good laterally, and there's a sense of real weight to the localized sounds. However, I've never gotten a convincing sense of front to back depth or layering when listening to AIIIs - relative to many other speaker designs.
If that's your issue, I'm not sure that a new amp is going to change that.
