The quest for the ultimate recording method is an absolute waste of time. Why? Because there is no such thing as accurate reproduction, and 'accuracy' when dealing with something such as sound is an incredibly subjective measurement.
There is no one 'sound' just as there is no one 'red' or 'blue.' It's all a matter of interpretation, and its affected by so many uncontrollable attributes before it even reaches tape; before it even reaches the mixer; before it even enters the microphone.
Who's definition of 'good sound' do we accept? The engineer's? The producer's? A person sitting in the studio? The drummer who thought he sounded one way, only to find his sound compressed and EQed in the final product? Before the product even gets to be mastered it has gone through a series of unnatural modifications.
This is a huge audiophile game; it's a huge game for anyone who's looking for pedantic fun. Some things cannot be put into an orderly, measurable, qualitative package. Thank God. Imagine if Mozart's crowd spent half of their analysis critiquing the acoustics of the auditorium; imagine if the audience of Woodstock complained in vague terms that the sound wasn't "crisp" or "life like."
As someone who used to be a huge proponent of analog I can safely say that no digital format sounds quite right to me, and I can even throw out claims such as "vinyl is more warm," or "at a party, analog brings more energy into the music." It's nice for me to believe, but really -- 90% of the people don't care. Or who knows, I could be suffering from a placebo effect.
And using a club soundsystem to judge sound quality is well -- strange. If anything (at least going by traditional audiophile standards), a club is going to be the worst place to judge sound. Not to mention DJ equipment is generally designed for function, durability, and sheer power -- not perfect harmonics. A true audiophile would probably turn his nose up at a beloved Technics 1200 and insist his $10,000 digital turntable is superior. And he might be right. But who cares? He's overly anal with too much time and money on his hands.
