I too have been to my share of shows and I have better sound at home that probably 95%+ of the places I’ve listened to shows. Years ago, I saw Samantha Fish doing her schtick in the middle of an outdoor art fair. I really felt sorry for her. She is really good and the band she had that day were tight and yet they sounded pretty bad! Locally we have a couple of theaters and our symphony hall that need almost no amplification to sound fabulous, but it doesn’t matter what equipment or how many watts they use, an auditorium or any multipurpose building is never going to sound as good.
Oh and my equipment at home is okay, but nowhere near high end.
