Good way to dampen tonearm?

Marigo VTS tuning dots are one possibility, amusicdirect.com also has a tonearm wrap,perhaps what Vanderstephan is talking about.

Ralph Karsten at Atma-Sphere (www.atma-sphere.com) sells a high quality tone arm wrap that may interest you. Check it out, Ralph can give you more information. Happy Listening

I have used tape that given to me last year. Not sure if it is Teflon or something else, but i ran the tape from the 'headshell' to just above where the bearing housing is and it made an improvement.

Things became clearer, it cured a bit of tenseness. Detail stood out clearer, transients were sharper.

there is also a suggestion of inserting a strip of balsa into the tube. you have to be carefull not to foul the tonearm cables so that anti-skate is not affected or flat out breaking the cable. The balsa should be just a bit wider that the interal tube so that it firmly presses against the walls of the tonearm tube. I expect this will do even more to dampen vibration.

Semi, follow the link in my post above and it discusses the resonance inherent in everything and why it is important to have the resonance of the cartridge/arm combo at the proper frequency.

There are arms made of wood and carbon fiber BTW.

I guess I need a new dictionary too.

A small collar of dynamat extreme (a car damping material)
inproved my rega tonearm. In fact I used at a number of locations on my old turntable which tought me how substantial and corrupting is all the radiating and extranous energy going everywhere in a turntable.
Tuff job getting rid of it all...
