"Still, I am missing your point.  (If you were missing my point, I’d be happy to reword it.) Regarding my English, feel free to lecture me, you will find lots of issues with my grammar. Whenever I post a question though, I do my best to not confuse the community."

You English is fine and comprehensible enough, as is the OP's.  You had criticized the OP's English phrasings, unnecessarily... this is why I wanted to point out that you ought not throw stones.  I saw no need for you to be hostile towards the OP's grammar, particularly since yours isn't textbook either.  Often, in a forum such as this or in everyday life in general, mine isn't textbook either.  And, it doesn't need to be textbook; this is an informal forum, and usually we on this forum understand each other well enough, even in our disagreements.

@curtdr I agree with you on "no need to be hostile". 

I am on the fence about "comprehensible enough, as is the OP's." I am very confused about the title in several ways and it's probably just me. 

And I explained myself back and forth, what bugs me, no need to repeat myself.

We’ve been trying out equipment for over 50 years, trying to find the best reproduction of music for our enjoyment. In my experience over that period, I’ve come to the conclusion that, as a matter of routine, the correlation between price and audio quality is very tenuous. It’s true that expensive gear generally has very nice fit and finish, usually satisfies the visual senses, and rarely sounds bad, but I’ve gotten great sound from very modestly priced systems and mediocre results from expensive ones. The one thing I am absolutely positive about is that I have wasted an enormous amount of dough over the decades (driven largely by ego).  At least I acquired a little wisdom from it.

The system that gets the most play in our home is in our bedroom, and we often play it overnight. It’s composed of two kits, an Akitika PR-102 preamp and an Elekit TU8600S 300B SET amplifier, plus Altec Valencia speakers. Total cost (including WE tubes) was under $5k. It would sound just about as good with a Luxman R-1070 or something similar and cost half as much.

That's easy:  Thiel.

@soix ​@musicaddict The idea that you have to spend $15k to possibly get good sound is the kind of thing I expect people to say who buy their audio the same way they buy their luxury cars.  They have a great deal of disposable income and can't possibly think they can get value at a price the rest of us mere mortals work at.

Your endorsement of the Joseph Audio Perspective2 is interesting.  Perhaps you should look at this SEAS kit system, which uses the same tweeter and similar SEAS mid-bass drivers in a transmission line cabinet and crossover designed by Joe D'Appolito.   The guy is unloading them for $750.  The kit is $2200 and in the end, is comparable to your Joseph Audio Perspective2.
