You just made it much easier for me to decide what I should build. I found a store selling the entire Alpha line in another EEC county so I can build any speaker I want from the Studio or Thermionic line for my little 14W tube amp that I plan to triode wire (power will drop to about 6W).How big is really the step up from the 2 Pi to the Thermionic 3 Pi? And how much different is the Thermionic 3 Pi and 4 Pi?
