What tube amp are you using with Von Schweikert VR series speakers

My budget would be 1500 to 3000 used. 60 wpc seems to drive my speakers nicely.

I bi-amped my VR4 genIIIs using a TAD 60 on the top, B&K M200’s on the bass. This sounded quite nice. I ran the TAD in triode mode (30watts). Running the TAD full range left me with some flabby bass evening ultralinear mode (50 watts).

They may be out of your budget, even used, but I think you owe it to yourself to hear these speakers with OTL tube amps. The Atma-sphere M-60 might do the job. (or at least the MA-1). I find that OTL has a clarity, timbre, immediacy etc that overrides other considerations - to my ear (triode might be even better, but that wont work with your speakers). Whatever you do, get a deal where you can try the amp in your room and with your speakers before final decision. 

I've used a Conrad Johnson Classic 120SE with great synergy driving my VR7HSE

May I ask what pre you were using at that time?
