This is just the type of reductive sentiment that leads to people with $40,000 systems and fifty records. Most of them Diana Krall and Holly Cole. To properly get the feel for a system, the maximum number of records should be used for evaluation and those should be ones that you like. This common ground idea really makes no sense.
To take Pererayer's example of "Something Else", I could be talking about the 45RPM reissue, you could be talking about a first BN pressing, the next person could have a King Super Analog Japanese pressing and someone else could have the 90s digitally sourced reissue. Other than agreeing that this is one fine bit of playing, we are not apt to learn much else. Then again, we could all buy yet another copy and all have the same one, and still no one would agree on anything.
