piano3,
Here is what I think.
You are not supposed to think and understand, but adhere to the conventionally stipulated rules determining what applies to what and what follows from what. Intuitive thinking varies with mental state and context hence is considered provisional, doubtable and lacking acuity. Cold nonpsychological logic never fails so it was chosen as the main scientific method.
But not quite. We are dealing with a probabilistic, approximative system built on wishful suppositions, taken-for-granted assumptions, untenable premises, unimposable specifications, logical acrobatics and reckless trickery. There is no room for conceptual and methodological rigor, clear-cut definitions and distinctions and clean classifications. What "closed form solution" means depends on who you ask.

What about different speakers and sources too, how would you arrange your system to play Stravinsky's jazz?

"Guru" is a term that is used for someone who can show the way to enlightenment (spiritual freedom). It is falsely used by the modern society for people with knowledge in all other fields, but that is the same missunderstanding as "Yoga" isn't a modern gymnastic to loose weight.
What your "Guru" told you is nonsense, because why should it be at least two? Why not twenty or as many, as there are different music genres exist? Why not 134? Or maybe 521 different amps?
The truth is, there are audio systems existing that are capable to play music, to allow the listener to understand why musicians play together and let every player shine with its own style and grace. But those systems are rare as hens teeth. Most of the systems displayed, showed and auditioned are HIFI-SYSTEMS. They can play hifi and they turn evey piece they play into hifi, not music. To have understood this potential gap between music and hifi needs knowledge, experience in listening and, if you aim to be a "Guru", the wisdom to know how to achieve this. I think the audio Gurus that have that knowledge and wisdom are as rare as those real Gurus, who have nothing to do with audio, music and hifi at all but prefer to listen to the clap of one hand.

According to Wikipedia: "Music is the art of arranging sounds in time to produce a composition through the elements of melody, harmony, rhythm, and timbre.[1]"
To say a "hi-fi" doesn't reproduce music is flawed. The sound of my BMW is "music to my ears". I used to listen to music on AM radio. Was it hi-fi? No. It was music though. Music is just organized noise and it doesn't matter what makes that noise - it's music.
Hi-Fi is just a way of saying it will reproduce full range sound. Hi-Fi as opposed to lo-fi like AM. Hi-fi as opposed to guitar amps. Now they have another thing called HD Audio, right? It's "higher fi than hi-fi" or something.
In any case it's more about acoustics than anything else, isn't it? How good would Yo Yo Ma sound if he played in the middle of a forest instead of in a concert hall with all of it's acoustics and natural reverb? How about a big band playing in a metro station? Too much echo and reverb, no? If you asked the band what they were doing, they'd say "playing music".
The real answer to "why has single ended output become popular" is probably related to audiophoolery if this thread is anything to go by but that's just my opinion - I could be wrong.
The technical answer of course is cost and simplicity. If you go SE, you save two output tubes and a phase splitter so it's cheaper and simpler unless it's more than about 5 Watts.
Even with junk parts, I can't make an SE amp as cheap as this one: Chinese 6J1 + FU32 Class A SE 3+3 W

Scott your correct too unfortunately many of us do not have the luxury of space
to accomodate 2 or 3 sets of equipment. What the guru meant was at least 2 amplifiers that suit that system. I myself have built a few Hypex including 400 watts as well as 2 tweaked Aksa 100 & tested them on my ML Odyssey, they didn't sound too bad at all but when I bought a pair of Prima Luna Dialogue 7 synergy was obtained it simply just killed the other amps. Btw Im not saying that tube sounds better ya. It's just my own experience. Anyway one cannot have it all regardless, speakers in itself will present different flavors with different design approach.
Cheers
Like me, Sumotan is Indonesian. The word guru is commonly used here: wordhippo.com - What does guru mean in Indonesian?

An antecedent is required to make a comparison (to produce a thought at all).
The SE sound is often described as "musical" and "natural" while the PP sound is described as "clean" (free from even order impurities).

Well, you know, the internet is a source for all kinds of false information.
To learn, what is correct and what is a false used term doesn't work with the internet. You can't even google it, you will receive onehundretthousand answers.
But you can read a book of whisdom. It will tell you.
What I told you is the true terms meaning.
And I gave you another example of a misunderstood word, Yoga.
If you don't believe me, don't be a fool and ask the internet. You will become correct and wrong answers. But you still prefer to choose the wrong answer.
Sad thing. Your a beliefer of wrongly used terms, like so many others today.
The internet is never a source for first hand reliable information. Ask your professor, what happens if you state internet sources in your diploma work. They will laugh about you. Its not allowed to do so. For a good reason.

Obviously, you don't understand the difference and what I meant.
Sometimes, words are not enough to clarify.
But someone, who has no clue about the subject, can't understand what I meant, no word can describe it good enough. Its a part of the soul, and when the soul in music is missing, its just hifi. And the most audio systems are able to reproduce just that. Nothing more. No soul. Maybe you understand.
LMAO Horses*it. There are PLENTY of accredited scientific resources online. That's why nobody buys a set of f*cking encycopedias anymore.
I'll take your word for it - I read what you said on the internet so it much be wrong.
Hello v4lve lover, would you please elaborate ? I have a large stash of PL36 and have found a few schematics, but the opinion are divergent about them. Have you actually built something with them ? SE or PP ?
thanks !
Charles
I've build a PP amp using the 6P31S which is a Soviet EL36 and it was quite good. I got about 20W out of a pair in push pull triode using 320V B+, automagic grid bias set to 60mA, load 2k2 Ra-a
I get all my tube amp design advice from this forum. Unfortunately the only way I can get to this forum is through the Internet.
Institutionalized is a better word. What you largely come across is the perverse drifts within science.
After battling power supplies for an OTL Class A 'Single Ended' I think I will steal that. Attempting passive filters results a some cerebral kinks that need ironing out.
