Your writings seem to have realized the value of competent room treatments.
There is also something else that you probably didn't realize about your pro audio friend.
Higher end pro audio speakers can kick some serious hiny and walk all over most home audio speakers. A lot of engineering goes into them.
TAD, Meyer Sound, etc pro monitors are no joke. Higher end PA speakers can blow your socks off. They will sound good with anything.
I have different audiophile speakers, but, my favorite are a pair of PA horns that run around 10 to 12k a pair, not that much compared to the world of audiophilia. I keep them in my modest lake cabin. When the weather's good, i roll them outside and party outdoors. They make me not wanna go back home and deal with the spouse, regular life, etc.
Hopefully you find it entertaining and/or relatable.
Feedback, comments, brickbats, bouquets and anything in between most welcome.
