Validation

I don't need it but it's fun to watch people's faces, they generally aren't ready for it and are smiling/laughing every time. Never had anyone give me a "meh" afterwards. The best responses were from my kids' friends - seems like everybody owns a little bluetooth speaker for their whole house and that's it!

The validation of acoustics concepts  occur in experiments...

 Any other validation has nothing to do with sound quality...

I  don’t need validation from anyone else.   Did I put together the system for them or me.  I try to keep my ego in check.  It’s always cost me money when it shows up

I sometimes wonder what my local dealer would think of my system, in my room, but mostly because I didn’t buy everything from him. Although he does sell some of the gear I’ve bought used. 

But not for validation, rather ideas/suggestions from a different perspective as no one else besides my wife has any interest, and she is happy as is.

I couldn't possibly care less.
