That would be mistracking. When I listened to your samples I noticed that
the problem seems to be far worse in the right channel.

I've noticed that too. Why *is* that? My old stylus had a similar
problem (its right channel was distorted) and that's why I replaced
it...could part of this have carried over thanks to tracking weight
errors?

Sounds like the anti-skating force is badly wrong.


And the tracking weight may also be set too low.

Excessive treble distortion at the inner grooves is, regrettably, only
be expected with vinyl.

Since vinyl the only format with "grooves", I would expect this to be
a true statement. However, there's not much point to such a statement,
as stated.


Certainly there is, if the original poster thinks that there's
something wrong with his turntable. In fact, he's just hearing a basic
defect of the medium.


Not true at all. My turntable doesn't have audible inner groove
sibilance. And I'll bet that yours doesn't either.


Of course yours does, you're just in denial.

BTW, vinyl is not the only medium with 'grooves', but it's a CAV
medium, whereas CD is CLV and hence has a constant data rate.


A series of pits isn't a groove. Look it up if you don't believe me.


The basic fact remains that CLV media have constant data rates, and
CAV media like LPs don't. The Edison cylinder at least got *that*
right! :-)
