I get overpaid to do live sound production/mixing and actually have some shows sort of booked for September (we'll see about that, but I mention it because I don't want anybody worrying about me), so I'm to blame for some reinforced concert sound. That's right. It's my fault. That said, there are gigantic differences between un-reinforced performances and everything else, as well as recorded vs live...so what? Do you think watching an F1 race is like driving? Food shows are like eating? Are they supposed to be? No. I can play an acoustic guitar any time (not while driving...that's illegal) and yeah...it sounds groovy, but is a symphony going to set up in my house to play Benjamin Britton for me? Doubtful, and there's not enough parking. My hifi rig makes music sound good enough to be very enjoyable, concerts are fun, get over it.
The Absolute Sound vs Pleasing Sound
I have changed my mind about this over the years. The absolute sound (closest to real live music) just can't be accomplished even though I have heard some spectacular systems that get close on some music. So years ago I changed my system to give me the sound I wanted. I'm much happier now and all my music collection can be enjoyed for what it is: Recorded music.
