Perhaps it's a sacrilege to say on the tubes forum, but I do not believe that vacuum tube circuits are inherently superior to silicon. They are pretty cool though. A good tube amp sounds great, and the glow of the filaments is enchanting. The blue glow off my 2A3's pulses with the music, and it is like watching the dancing flames of a fire. And hey, if you get hit by a nuclear blast, your valve gear will still work after the EMF pulse. That's always a bonus.
