VAC preamps - too expensive?

Going back to the many skeptics and sour grape guys in 2021.  Tell me.....how many companies are there where the CEO (Kevin Hayes) is highly likely to answer the phone when you contact the company??....and then he will speak with you for as long as necessary to thoroughly answer your question!! My Sig Mkii se with phono stage is an amazing piece of precision equipment that compliments my entire system. I can only dream as to "how much" the Master series could improve upon the sonic results I am so fortunate to experience.

I believe most people DO hear diminishing returns, otherwise, using your $22k versus $4k streamer example, you would not have spent the additional $18k on another streamer.  Maybe we agree that diminishing incremental improvements become more and more difficult to discern, especially when we're trying to improve a less expensive piece of gear, that very likely, is already a formidable performer!....that never ending quest for getting to that next level of sonic bliss.  Diminishing return improvements are VERY expensive as you know, and only because we are passionate about our music, does even a small improvement in sonic character, justify spending 5x more for such an incremental result.
