Which speaker is best for my Krell amp?

You may try Vienna Acoustics Mozart or Beethoven and add Rel sub to it you will not disappointed.

Thiel 2.4

I would love hear my VA hooked up to a Krell. Maby you can get an inhouse demo.

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.

Pair of used Wilson Watt 3 Puppy 2 will be really great and could be the last speakers you need to buy. They sell used about $4200 in excellent condition. Also, consider the Von Schweikert VR-4 for about $1500 used, which could fit your "best bang for buck" request.
