Honestly my experience with said "audiophile grade meats" has never really wow'd me vs more pedestrian priced cuts.
I find much success with Black Angus AAA cuts. I never go higher than that. There is a prime designation that is a level above it in our local places, but I never found it to taste any better.
I have tried many of the ~$30 burgers in Toronto and they are good - but don't represent good value for me. A fav burger is one out in Saskatoon at a place called Stacked. I recall their Waygu burger is around $15. It is excellent, and does present good value to me. Their standard burgers are good too, at around $9.
I also love that much of BBQ is meant to make excellent food from cheaper cuts anyway.
But, if you have the pockets and want to experiment - go for it!
