Brooks,I am enjoying the Viva Verona XLs.They are very dynamic and throw a huge soundstage.They have good extension {top/bottom} and that magical SET midrange.I am always curious about exceptional solid-state designs,due to the fact that I could leave it running, with little warm-up time.The Vivas take about 15 minutes to open up.The heat problems of the older Vivas {IE: non ventilated chassis, has been cured}.As I understand, that the stored heat in the chassis would take component parts out of their operating parameters and occasionally blow-up.I was looking for a simple tube complement {only one driver/output tube} and the replacements are not expensive.I understand that the Krell phonos were subject to this same problem.They sounded good until the class-A circuit got hot-then the sound deteriorated {chassis needed ventilating }.
Do you know whether the Audio Net amps are available for home demonstration? Not that I am dissatisfied with the Vivas,but am curious.Thanks for your post.
