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.
Does this make sense and is it true?
Yes, although not 'definition', just more extended treble,
Bull****.
It was ever your habit to ignore facts. The treble extension of vinyl
is entirely related to groove speed, which is a function of radius and
rotation speed. In fact, the outer grooves of a 33.3 LP have higher
groove speed than the outer grooves of a 7" 45, but a 12" 45 has the
capacity for a third of an octave higher treble. Of course, it's back
down below the outer grooves of a standard LP when it gets to the
inner grooves, but that's CAV discs for you!
hence the
existence of 'audiophile' 12" 45s by RCA and others. OTOH, surface
noise is higher,
More bull****.
Just simple truth, and we know that you can't handle that. The output
of a MM or MC cartridge is velocity-sensitive, so speed up the groove
and the surface noise gets louder. It ain't rocket science!
