OK. I'm *fairly* sure I can hear a difference between
LP-CD recordings and LP-original. Not absolutely sure mind, no rigorous
test, just mild and recreational observation. Then I'm told there can't
be any difference.
No, you've been told that there shouldn't be a difference, and that
others have achieved that result.

And I haven't been told the basis of that reasoning.

It's simple. It is well known and fairly easy to show that the CD format
does not alter musical signals taken off of a LP in any audible way.

Think of it as a plumbing problem. Think of music as being water. Think of
the LP as being a 1/2" pipe. Think of the CD as being a 4" pipe. If there's
a smooth coupling from the 1/2" pipe to the 4" pipe, how much is the 4" pipe
going to cut back on the flow of the water? Obviously, the 1/2" pipe is the
weakest link and will set the pace for the flow of water.


Depends what's flowing through the pipe I would have thought - oil and
water?!

Actaully, that's a good analogy because it suggests certain fixed and
known boundaries. In methodological terms I quite like this approach
because it gives you something to 'aim for' in field work. The problem
is always knowing what the boundaries (or pipe diameter in your analogy)
are, and you (I) end up making assumptions. Some are perfectly
reasonable, but if you contrive any test that rules out anything beyond
the pipe/boundaries you *could* miss something.
