I've owend the NHT 3.3, and Goldi, and still own two KAV-250a amps and a KAV-250a/3. The 3.3 would probably be too "bright" on the top end, especially with a Krell. The Goldi would be good though. It's top end is better (not so bright), and while the Goldi's bass is very good, it is not the absolute "tightest", but the Krell should control the bass quite nicely. Mirage and AR are both a step down in performance. The B & W's aren't bad though, but don't have as good overall real world performance as the Goldi. They do some things very well, but I think are not as ultimately satisfying as the Gold1.
