This really is a pointless discussion, because you are convinced that
none of the best equipment on the market is worth the price that is
asked of it, because you have deemed it so.
While I "feel your pain", the discussion, for myself at least, has not been pointless at all. I have learned a fair bit about the subject during the course of this rant, both reasonably and unreasonably stated. Whenever I can learn something new, I always consider it a good day (even if I may have felt better before I learned the truth).

There are a lot of variables that go into the equation. For example. the large manufactures can and do produce equipment that the small guys cannot compete with. If one looks at the technology packed into a reference Denon, Sony ES, Onkyo, Yamaha, etc, piece of gear, a small guy trying to make the same thing would have to charge a substantial amount more to achieve something near the same quality, and it most likely will have more issues with as well. The unit cost for these specialty audio manufactures is higher, and that cost gets passed along.
Another example, the Polk Lsi series is a very well engineered mass market speaker, and one that probably is as good or better than than the smaller boutique speaker outfits at their price points. They can buy those vifa tweeters at a lower price point due to their size, and pass it on.
So, for most of us that to live within budgets, we try to get the best sound for the dollar, which excludes us from owing the most expensive items. That does not mean that we have to settle for anything less that the best we can afford. Well, for affluent who feel the same way we do, it opens doors for them we do not have, and more power to them for it.
I get my maximum value by taking something like a Harmon Kardon Citation II, and restoring it with a new front end topology, better parts power supply, etc, and make use of those very nice output transformers. If I could afford a 30K amp, I would at least try it out and see for myself if it is worth it.
And that is the part that is worthless to debate. Everyone's value of worth is based on their life experiences, and, as far as that goes. "viva la difference" aa
