It's worth auditioning Alon speakers. I have had the Alon V MkII and now the Circe, both with a VT100MKII (although I use an Audio Valve preamp). I've tried these speakers with a number of other tube amps in the $3k to $6k range, and the ARC sounded best. The combination is open, extended, neutral, and incredibly dynamic. In addition, I have recently heard the newer Lotus line from Alon, and it sounds fabulous.
Good luck
