This question has probably been asked before but I would like to be a bit more specific. I am considering buying a SET amp that uses the 845 triode. It is one of the most powerful triodes. Klipschorns and LaScala's are out of the equation due to price(new and/or used) and transporting them. I am thinking that the Heresy would work well. Are models like the Forte, Chorus, and KG4's viable in this application ? Would any of the more recent models fit the bill ? I remember when I knew the specs of every Klipsch model. There are so many now. I cannot keep up.
