This is only somewhat related, but I have long been aware that the number one major difference between live music and reproduced is, for me at least, the lack of "physicality" in reproduced---the lack of feeling the music physically in one's body through a home system. That is partly because live music is often much, much louder than we play it on our systems, but also because very few home systems reach low enough in frequency at high enough SPL levels to provide the physicality of live music. I'm dying to hear the Eminent Technology Rotary Woofer (response down to 1Hz!).
Then there is the probability that few recordings contain the very low frequencies responsible for that physicality. Even if they did, how many cartridges/pickup arms could follow a groove, should it even be possible to be cut into a lacquer, with frequencies that low? I am all too aware that only the tiny hairs in my ears (cochlea) are being vibrated by the sound from speakers, not my skin, and certainly not my bones.
