Jaydiane,
As Rushton mentioned, I have recently moved from Berning to Atma-Sphere MA1s, and am pleased with the change. They both are very good matches, it really comes down to personal taste.
In my rig, the MA1s provide greater ability to untangle complex orchestral music, and the music emerges from a blacker background. Music is effortless and natural. The Berning has a bit more energy on rock records, and is directionally more of a solid state sounds with tonal balance that might just tip up the lower mids, and upper bass region a bit.
The Berning is high on goosebump factor, and certainly the easiest to own of any tube amps I've had: it's small, runs cool, auto-bias, incredible tube life.
I also have a friend who runs Cary Sixpacs, and although I haven't heard them, he is pleased as punch.
If budget is not an issue, I think Bobby still will personally recommend the Joule VZN-100 monoblocks over all others. The good news is that you've got a speaker that will accurately allow you to hear the differences in all these terrific amps. It's a good problem to have!
Cheers,
Spencer
