To summarise, "it aint what you do but the way that you do it". I confess I have'nt heard a 45, but all the rest in various manifestations. To me, there is more difference between amps, than between valves. It is the skill of the designer and quality of parts used, rather than the valve, that counts. Particularly of course, the quality and size of output transformers. To me the classical, euphonic, tube magic comes from the 300B, that is the amp which will grab you at a show, but may not pass a prolonged critical listen. Me, I use the 845 in a Viva Solista, just made Class A in stereophile. I know, I can hear the chorus of "so what" over here in the UK
What would you say is the better sounding SET amp?
45 ,VT52 ,2A3 ,300B ,845 ,EL34 ,6550, KT88 etc I know theres others .I have messed with many SETs and keep going back to 45 SET.Just wondering what other SET types think
