What is better to own cost wise sound advantage single ended and push pull ?
Did anyone answer this part of your question? I may have missed it, I am basically blind in one eye, and I do miss things.
My understanding of electronic theory is limited, but I believe that push-pull is a more efficient way to make power, and therefore, if all else is equal, push-pull watts are cheaper than SET watts. But I am personally NOT saying one is better than the other.
I have a friend that says his pair of (SET) Cary 805s are the best thing since white bread. If you have some spare time, put those in as a search engine and see what comes up. You could also read what Dennis Had has to say about his SET (I think I remember that they are called "Inspire") amps. In a nutshell, he claims that with the right speaker (a fairly efficient one) they literally breathe.
On the other hand, about 25 years ago I was buying some tubes (over the phone) from Andy at Vintage tubes, and I engaged him in a conversation comparing the two (SET & push pull) and he was telling me about what 200 watts of "pure class A" push-pull sounded like, and I believe I remember he used the term "liquid fire" in an orgasmic tone of voice.
As for my own experience, I have owned three tube amps & they have all been push-pull. They have, at various times, all performed magic for me. But magic is a subjective & relative term, and remember that I specified "for me."
On edit: and I don’t think "romantic" was necessarily a bad modifier for you to use. "Romantic" is in the ears and eyes of the beholder. When I sit down with a glass of wine or harder liquor or even a beer to enjoy the sound of 23 vacuum tubes, that is about as close as I get to romance these days.
