speakers for krell 400xi

listen to jazz and am interested in anyone with the int.krell and what speakers run well with unit...
I am using Alon I's (now called Nola) and a Rega Planet. The sound is airy, open, with excellent imaging.

I've heard that it mates well with VS VR series speakers but haven't actually heard the combo. I have a 2250 and 280P that I use with Energy Veritas speakers with very nice results.
