I'd like to also address something akhilesh said. After akhilesh proposed the question: "Which offers greater "fidelity"? he proclaimed "I think SS amps for sure" I must state that I disagree with this statement 100% I firmly believe that SET's offer the greatest fidelity! According to the Merriam-Webster Collage dictionary Fidelity means:

1 a : the quality or state of being faithful b : accuracy in details : EXACTNESS
2 : the degree to which an electronic device (as a record player, radio, or television) accurately reproduces its effect (as sound or picture)

So if we use #1 as the main meaning, then for true musical fidelity we need to have accuracy in details or "exactness". This is exactly what an SET offers, Musical accuracy. Think about it. Isn't that what everyone who owns an SET says? Just how much it sounds like real music! How can it sound closer to real music and be less accuarte? It CANNOT! Unfortunately, many people look at what the microphone produces. They then compare that signal to another electrical signal and claim how accurately one electronic signal is to the other electronic signal. But our ears are not microphones, they hear completely differently. If you don't believe that statement to be true, please explain why, in any setting, where the music and singers are NOT amplified electrically you'll never hear simbilance (that exaggerated sssss sound at the end of words) yet take that same performance, record it and listen to what the microphone heard and BAM simbilance is now introduced and heard. So either a) It wasn't there in the performance and was later introduced by the mic or b) our ears don't hear like mics do. Either way you look at it, I don't want it added to the music. This is a tough subject and could go on and on. However IMHO, SET's are more accurate than solid state in that they sound more like real music. Solid state is more accurate than an SET when you are comparing one electronic signal to another electronic signal. Just like the second meaning in the dictionary...

That's my 2 cents worth.
