Arms without anti-skating (ATP-12T)

I apply Gruv Glide to my records after I do a washing. The product claims less surface noise, better highs, midrange and bass.

Is this what you are referring too?

I also use this after cleaning, it seems to 'ease' tip tracing somehow, reduce noise, and eliminates static. I find it a definite improvement for critical auditioning and for general listening enjoyment.

BTW everyone, "PAM" is non-stick cooking utensil spray, not for records.

I will be able to test this last statement in the next couple of months. I've had an ATP-12T with a Denon DL-103R for a number of months and the combo has certainly performed well. The 103R is full of detail as it has been retipped by Soundsmith with the medium grade cantilever and line contact stylus. I have run the cart between 2.5 to 2.7 grams with success.

I recently purchased an AR-XB that will be hot rodded by marcmorin in the near future. I'm not changing out the arm so it will not have an anti-skate device. The effective mass of the AR arm is about 11 grams and the first cartridge I intend to use is the one that originally came with the TT: a Shure M91ED. It may get a JICO SAS stylus at some point in the future.

It doesn't make sense to me that AR would sell their XA and XBs with a cart that caused a problem, so from the conclusion above the M91ED is probably not "heavily damped". So what carts are considered "heavily damped" or conversely which ones are lightly damped that will work with an 11 gram arm that is without anti skate?

Styli are always underdamped, some are more underdamped than others, but they are never heavily damped. It just doesn´t work.

Hi, just to clarify, my sentence stemmed from page 6 in that paper:

"[...] on modulated grooves, the [stylus] drag depends on the cartridge used. This is mainly due to the mechanical damping in the pick-up suspension."

This means that a more damped cartridge will drag more. We also know (see previous posts) that more drag yields more skating, and that the skating/VTF ratio related by modulation is higher since in this case the drag is only partly related by VTF. That's why I said that light arm - generally related to a low VTF - and high damping can be a problem. I meant that it could lead to increase the VTF so much that it would exceed the maximum VTF of the cartridge, but that's a theoretical case, I didn't care to check experimentally whether it happened in reality. Besides, all the light arms I know of have antiskating so there is no point in increasing the VTF.

I hope this helps.

I understand what You are saying, but in reality the damping is inversely proportional to compliance. That means low compliance with higher VTF also have much higher damping than those made for low VTF. You cannot have a stylus with high damping made for low VTF, the tracking would be terribly bad.

Gusten, the tech sheet on the GE CD cartridge states, that damping helps trackability at the freq. extremes at the expense of overall sound quality(thinking shure here), the tech paper is on the internet.

I haven´t read that, but I guess by freq. extremes You mean very high freq. which is a different situation.

Alright..you guys went in did it

Ordered some Gruv Glide...worth a try. My only concern is it is a solid (not a liquid) and the potential effects via friction,,,which it is supposed to reduce...but we'll see...
