Tubes are really only best with electrostats once the transformers are removed. I.e. no impedence matching transformer on the panels and no transformer on the tube amp. This does mean the amp has to be optimized for the panels. But that's the best and most cost effective way to do it. I wouldn't rip up your JA-30, but for aftermarket amps with aftermarket speakers its alot tougher to get it great. I think the old acoustats were designed like that.
