Yeah, Pass is an odd duck. He has his fair share of great electronics, and his fair share of quack-job electronics too. And, he still contributes heavily to the DIY community!
We do have some other guys that contribute heavily to the commercial offerings and the DIY community too (though they don't have the odd-ball designs like Pass). But, I'm thinking of Dennis Murphy, Jeff Bagby, and Douglas Self.
If you ever think about moving towards some true reference DIY designs on the amps and electronics, Douglas Self has written several books, and his DIY products are available (but not cheap).

I'm looking at eventually doing my own PCB etching, taking it down to that level!
Once you start the DIY path, you start to understand the limitations on the commercial designs, most specifically how commercial designs make design decisions and trade offs in performance in order to meet a price point. For DIY, you are not held to those same constraints.
Then, you also start to see how silly all these snake oil and magic cable believers really are! Clearly, these people don't have a clue when it comes to science, data, technology, etc, so they fall back onto voodoo science, fancy terms, and "trust your ears"
Yeah, I rotate gear and speakers too, but in practice I tend to be lazy so I stick with a particular setup for quite a while before making a swap.
