Stylus Drag


Hello all,

I was wondering, does stylus drag vary significantly based on the musical content of a record: frequency or dynamic vs slow passages? If it does vary based on the musical content is this amount insignificant relative to the amount of overall drag arising from the friction of the needle in the groove?

The resaon I'm asking is to understand that even if the speed setting is compensated for stylus drag if at a micro level it is still varying based on the musical content and if this is heard sonically.

Thanks,

Andrew

Regarding the greater stylus drag with low compliance MC cartridges......I suspect it is also related to the higher tracking forces generally required with those over the MMs?
The logic and our hobby don't fit together. I have no clue
why the low compliance carts are produced which is the same
(in my case)as that they make no sense to me. Despite of
this (subjective) fact I own 2 or 3 of those. I know that something
is wrong with me but have no idea what is wrong
with the low compliance MC's. Can someone explain to me why
those are still produced?

Regards,
Good question my friend.
J Carr would certainly have an answer if he was lurking?
Dear Henry, 'J.Carr would...'. Since when my Aussie friend
become diplomatic? J. Carr is a very nice guy so one need
only to ask? J. Carr WILL you be so kind?

Hi Folks, thanks for your comments so far. Some comments from me:

I agree with Halcro that the Raven slows down when the needle hits the groove. I base this on the shift in speed as observed with the KAB strobe disk. So I usually set speed with the needle in the groove. So clearly stylus drag is impacting speed, but I can't tell if it deviates based on the fluctuations in modulation of the actual record on speed has been set taking average drag into account. But it apprears Halcro has observed changes in speed with havily modulated sections of the record using the TimeLine. The key question is whether or not this small change is audible.

I agree with Atmasphere and Mosin (in the other thread on turntable speed accuracy) that the best way to listen for speed stability is by assessing the soundstage expansiveness and the small, faint micro-dynmaic and timberal details in the recording, in addition to the sheer dynamics. These come across more clearly than possibly changes in pitch.

The best description I heard about TT's is that they are "rotating resonance machines". Very true! We need to worry about both speed and resonance.
