Stewart's last post made me think (extraordinary as that sounds); Does the
fact that a Vinyl single spins quicker mean the sound is more defined? As
you're covering more distance with the same amount of information you can
get better definition, i.e.. your higher frequencies appear longer on the
faster spinning record and are therefore easier to pick up.

The circumference of a 12" record is 12" x pi = 37.7"
Distance travelled in a minute = 37.7" x 33.3 = 1256.6"
1256.6 inches per minute = 0.53m/s

The circumference of a 7" record is 7" x pi = 22"
Distance travelled in a minute = 22" x 45 = 989.6"
989.6 inches per minute = 0.42m/s

So it seems that the first track of an LP is actually going 25% faster than
the start of a 7" single, and any point in the outside 2.5" of the LP will
be travelling faster than any point on the single. Obviously the size isn't
a factor on a 12" single, and they can indeed sound better.

In my experience, while you'd expect the end of a single to sound better
than the end of an LP, 7" singles often sounds worse, although I suspect
this is due to either singles being less well-made, the covers not being so
good at keeping out the dirt, or them being less well looked-after. Or me
buying them from car boot sales for 10p.
