My thought process is similar to yours (which should scare you).
If the sound is there, that's all that matters to me. I have seen some food dishes made with some of the very best and most expensive ingredients money can buy and sometimes they were meh, sometimes they were sublime and sometimes I downright did not like them.
The same is true of less expensive ingredients. It depends on how you cool it, the combination of ingredients and how you season it.
In other words, when paying for a great tasting meal, sometimes the most important parts are not the ingredients, but the knowledge of the chef. It it tastes better than a meal with better ingredients, I submit you would still choose that one because you like it better.
I think the same is true with the Tektons. First, not all companies want the same markup for their components. Some good components are inherently cheaper ti buy because the companies sell for less markup. So Eric may be getting good components that just simply cost less. He makes that decision with his ears.
And his tweeter array seems to have the right stuff to the point that it beats most other speakers with very expensive tweeters and midranges. It is the secret recipe and his trademark.
If it sounds better, it is worth more to me. If it sounds better and is even cheaper, I'm not really going to look a gift horse in the mouth and wonder why there aren't more expensive parts in it to push up my cost.
