Raul, all the clowns I know are really nice people. Pretty smart also.
I think you do them an injustice relating them to ignorant.

TONEARM DAMPING : DAMPED OR NOT ? ? USELESS ? ? WELCOMED ? ?
@rauliruegas, You and @lewm have it right - every application is different. Its more than the just the cartridge and its compliance. There is a decent article on tonearms in this Audio Magazine https://worldradiohistory.com/Archive-All-Audio/Archive-Audio/80s/Audio-1980-06.pdf, and as stated in the magazine - all materials have some damping capacity - https://sites.utexas.edu/taleff/files/2019/10/jmatersci_v28n9y1993p2395.pdf. The tonearm manufacture is literally between a rock and hard spot trying to design a tonearm for the multitude of table and cartridge designs that all together form a resonant system. But, as has been stated, if your cartridge has the option for viscous damping then it may be worthwhile trying - but its success aside from table/cartridge could also be music type - maybe good with classical but not with vocals. All the more reason for multiple arms and/or multiple tables LOL. Just some thoughts. |
many years ago Sumiko marketed the Analog Survival Kit that is a great analog accesory.A friend of mine, Warren Gehl (currently at ARC) was the designer of this product. I had pre-production and production sample that I used on my SME5, which really did seem to benefit from it, although it raised the mass of the arm which limited the number of cartridges I could use. Eventually I moved to the Triplanar, which has a damped arm tube and so I didn't need the Analog Survival Kit any longer. IMO, if you really want the most out of an LP, the arm tube should be damped in some manner. Warren also designed the platter pad I use. It is very effective in damping vibration in the LP, so it can't talk back to the stylus as its tracking the groove. Warren only made a few of these mats (less than 50) and the last one I saw sold used went for about $1200.00. IMO/IME the platter pad is an unsung but very important part of the LP playback alchemy. |
Atmasphere, I thought we were talking about oil or silicone based damping systems with troughs, paddles and goo. Obviously arm tubes can't ring which is why aluminum is frequently used. Stuff makes a worthless bell. It is the additional damping required to control a pronounced resonance peak you might see with certain arm cartridge combinations the worst being a very compliant cartridge in a heavy arm. Schroder uses wood arm wands because of their extremely damp nature. Kuzma machines aluminum conically to spread the resonance out of existence. SME does the same but in magnesium another relatively dead metal but lighter. Triplanar uses a composite tube with "coaxial damping" whatever that is. It also has a trough but I have never seen it in use and I suspect it would only be useful if you stuck something on it like a Shure V15. I have no idea why you would do that but hey, people do silly things. |
Sota and Basis make the best pads IMHO but I have not listened to a lot of them. I think the clamping method is more important. In most cases reflex clamping will work with all but the most severely warped records and I do not have an of those. Vacuum is the best but admittedly more complicated and expensive. Dohmann is going to release his vacuum clamping system soon and he has told me that once the record is clamped the compressor turns off! God knows how he is pulling that trick off. Obviously his mat has to seal the record without any leaks. Sota used a low vacuum system with the compressor running at a very low speed. I'm not sure what Basis or Techdas do in this regard. |
