| Gimbal vs unipivot tonearms Mijo, As I recall, the early 3D tonearms from VPI were warping at temperatures where a $4K tonearm, or any tonearm, should not warp. Like temps reached during shipment or on a very warm day in a non-air conditioned environment. But they did fix ... | |
| Gimbal vs unipivot tonearms In fairness to VPI, I think they long ago fixed the problem with warping of their 3-D tonearm due to heat. And the uniform 3-D structure is touted as an advantage, not a cheap shortcut as you imply. | |
| How to isolate turntable from footstep shake or vibration Haha on me. Thank you, thecarpathian, for correcting me. I was indeed thinking of the Tacoma bridge, not the Verrazano. Only today did I see my error. Anyway, the point of my analogy still stands, or falls.If the Verrazano were to shake itself to ... | |
| Gimbal vs unipivot tonearms Classic SME tonearms used a "knife-edge" bearing, which is definitely different from a unipivot but does allow for some "chatter". Mijostyn mentioned this in responding to Elliot's erroneous suggestion that his older SME tonearm was a unipivot. ... | |
| How to isolate turntable from footstep shake or vibration MC, You might be correct about the cause of the bridge collapse. I mentioned it more for the sake of humor than anything else, and my guess is or was that the resonant frequency of the bridge suspension(s) and the wind velocity had something to do... | |
| SOTA NOVA, HR-X VPI, Technics 1200G recommendations? Mijostyn, no matter what you may “think” and no matter what is your opinion, “velocity” and “speed” are not synonymous. We, all of us, may use them as such, but when we do so we are being sloppy, in a convenient sort of way. Why are we even arguin... | |
| 2020 update : JC Verdier La Platine Compared to the inertia of the platter (57kg!!!), I would think the inertia of the drive motor is trivial, regardless of its type or construction. Anyway, wouldn’t the inertia of the motor ADD to the speed constancy rather than subtract as the tex... | |
| How to isolate turntable from footstep shake or vibration Usually it’s a very bad idea to “suspend” on springs a turntable that already has a built in suspension. So I am surprised that a few recommended adding a sprung shelf. The two suspensions will inevitably fight each other which could end up with p... | |
| Dynavector Karat 17D3: retip for $500 or get something new? …..in your opinion.Thanks for the detailed and informative response, Dusty. It seems your guy can get closer to the original spec than I would have thought. | |
| Upper Level Vintage DD Strenghts and Weaknesses I would not spend big bucks on feet for speakers, but I would have any speaker, particularly if it is expected to reproduce deep bass, well and stably mounted on the floor. I recognize that sometimes there is a risk of acoustic coupling that can ... | |
| Upper Level Vintage DD Strenghts and Weaknesses These threads do tend to wander. I am afraid I am a guilty party. But c'est la vie and all that. | |
| Dynavector Karat 17D3: retip for $500 or get something new? Dear heyitsmedusty, It would be interesting if your re-tipper was able to replace like with like. That is, did he install a 17mm diamond cantilever with diamond tip? Was the tip the same shape as per the OEM stylus? If those two requirements we... | |
| Upper Level Vintage DD Strenghts and Weaknesses What is a "Townshend Podium"? Is it based on an inner tube (i.e., compressed air in a bladder)? If so, that might not be as deleterious as some other footers actual using springs or rubbery compounds. My objection is based on theory; I have never ... | |
| Upper Level Vintage DD Strenghts and Weaknesses I've said this before, but I do not see the benefit of using spongy or springy feet under any loudspeaker. I see only negative consequences, because some of the amplifier power delivered to drive the speaker diaphragm will then be used up in rock... | |
| Upper Level Vintage DD Strenghts and Weaknesses For even better results always sit on AT616 feet during listening sessions, as well. Two of them will provide ample support for most audiophile butts. AT616, there IS no substitute. |
