Cartridge ISOLATION; What Say You?
Everything vibrates. If the cartridge is rigidly attached to the head shell then this vibration travels through the head shell into the arm tube and so on, with the result the whole thing is vibrating. There are plenty of Peter Ledermann videos you can watch if you want to learn how big a problem this is. Interesting reading this from a guy who in the past has been completely dismissive of cart/tonearm compliance matching. Perhaps he's coming around? |
Thanks OP, good to see a few decent earnest audiophiles still around here. Ledermann’s Strain Gauge is good enough it more than likely will be next for me. There are not a lot of reviews but search around, they are there, and the consensus is the SG1 is right up there with the world’s best cost no object cartridges. We are talking $10k and up carts. At this level of course you are using a $10k and up phono stage. One review if I remember right was $30k or more of cart and stage and the SG1 was right there. This is with the stock power supply. There are gains to be made upgrading the power supply. Not that it is needed, but nice to know. Combine with being able to buy extra stylus/cantilever for dirt cheap, user-replaceable no less, it makes the SG1 about as much of a stone bargain no-brainer as can be. What makes it especially attractive for me is since it eliminates the need for a phono stage then selling the Herron the SG1 nets out to a very reasonable upgrade cost especially considering it should be like going from entry level Koetsu to their finest for only about $5k. Can hardly say no to that. |
atmasphere, " If the arm tube is not damped you're going to have problems!" I found this, makes my head spin, especially with short term memory issues. https://forum.audiogon.com/discussions/tonearm-damping-damped-or-not-useless-welcomed Are these two arms (rigidly mounted to my rigid plinth) considered Damped?

In any case, I gather you do not advocate adding a soft layer under the tonearm base, or adding a soft layer above any cartridge, correct? IOW, these 'soft' treatments can only be an improvement if they are solving a problem that could/should be otherwise avoided/eliminated, correct? |
I gather you do not advocate adding a soft layer under the tonearm base, or adding a soft layer above any cartridge, correct? Nor do I. So what happens around here over and over again, someone says something perfectly clear and uncontroversial, then someone else comes along twists it around to resemble nothing even close and fifteen immediately parrot the distortion. Here is what I actually said: The cartridge however is very low mass and has to track a violently undulating groove. It cannot just be free to move. It must be held rigidly, but yet also in a way that facilitates some vibration to dissipate into the more massive arm, while damping cartridge vibration, and all of this at the same time as not reflecting vibration right back down into the stylus. The Cartridge Enabler is not soft. Went out of my way to make clear it is not felt. Not soft. Engineered material. Not at all what people are talking about. |
millercarbon aside from full understanding of the ugly thing, it's ability to dissipate Jitter without being considered Soft: I thank, and not thank you, for the link and my learning about the essentially Jitter Free Strain-Guage Cartridges. Maybe I'll spend that much for my 75th Birthday in 2 years. Of course, that will lead to what Tonearm?
