There's also a lot of different things going on.
I can surely tell the difference between digital and analog versions of, say, Electric Ladyland or Dark Side of the Moon.
But it's more than that. Another poster mentioned the album art itself.
Then there's just the ritual of taking the record out of the album cover, gently placing it on the turntable, running the cleaner over it, placing the needle in the groove....
Then BAM! I'm transported back to 1970 - it's magical.
A Freeper posted last year about him and his wife listening to Dylan's Blood on the Tracks album on a rainy afternoon with a bottle of wine - again, magical.
Can't get that with a CD or MP3.
Sort of the same feeling as changing spark plugs, adjusting distributer gaps and brake pads only dont do these while stoned.
