Sorry I missed it what were you trying say?
I was just quoting your words from your post that I disagree with and I didn't realize that it was hypothetical. I suspect somewhere somebody has $500K worth of gear in their bedroom and it sounds fabulous.
Really the point is no matter how much money you spend playback can't sound better than the original source but it can be indistinguishable.
To me sound is binary it's better or it isn't price and how much better is irrelevant. The graph of sound quality vs dollars doesn't level out it just doesn't rise at the same rate and it doesn't dip at top end.
Now in the real world, your / my system price is relevant but my point remains the same. Money well spent will improve the sound until that final result is indistinguishable from the original but like infinity indistinguishable can never be obtained. Part of it is we don't have access to the masters and part of it is that reproduction adds artifacts that we can hear with enough training.
If I'm wrong please point out the flaws in my logic as my bank account would thank you.
