I find it funny that so many compare their system sound to live performance, yet so few see live performance much if at all. And even more odd is the fact that most then claim that their system is better than live sound, the object of the comparison.
Live acoustic music (that is, unamplified live music) has always been a benchmark by which stereo systems were judged. It is one of the few points of reference which we can compare a recording to, which is why people do it. I am personally a little skeptical of the utility of trying to do so, though, due to so many uncontrollable variables and the inherent subjective nature of such a comparison.
I would be hesitant to say "so few see live performance much if at all." I would say among audiophiles, many if not most probably get out to see live shows pretty regularly. Personally, I see live shows at my local symphony and concert hall many times a year, plus going to several clubs on a regular basis where I hear local bands (granted, these are usually amplified).
I do think that a recording can definitely sound better than a live performance. Of course, there again, "better" is a highly subjective term. But with a recording, you can get many takes until you get the perfect recording. In a live performance, you only get one take. In a recording, you can engineer the sound after it is recorded. In a live performance, it is what it is. In a recording, you can control the acoustics to make it sound how you want. In a live performance, the acoustics of the performance venue will leave an indelible mark on the sound. With a recording, you can alter the sound with the gear that you play it back with (adding warmth and liquidity to the sound with a tube amp, for example). With a live performance, you just get the natural sound of the instruments as they sound in that venue.
Good to see you posting Jim. Haven't heard from you in awhile.
