| High output MC cartridges In general I have not liked HOMC cartridges compared to any of many LOMC, MM, or MI types I’ve owned. I’ve owned Benz Glider (2 versions), Transfiguration Esprit, and a few Sumiko’s. Sumiko was just plain not good. The others are sitting in a draw... | |
| Moving Iron Carts or stick with LOMC If you’re going to own more than one or two cartridges, you really ought to sample an MI type. All the foregoing suggestions are good ones. If you’re going vintage also think about Acutex, Astatic, Glanz, and B&O. Most of these are high in c... | |
| What is the Best Tool to Measure Cartridge Azimuth? By the way, I agree that there is no need for a Foz if you have an oscilloscope and know how to use it (which many don’t). You still do need the test LP with 1kHz signal in one channel only. (Needs two bands, one for L channel only and one for R c... | |
| static Issues...anybody know why? What should it do for me? What are you trying to say? Is this in support of the notion that the stylus rubbing on the vinyl causes static charge accumulation? I disagree that this is a major cause, only because it appeared after reading the Shure ... | |
| Nasty Static on Vinyl Are you wearing leather soled shoes? Is your system on a wool carpet? If either is the case, change the environment accordingly. Grounding the tonearm is not so important as grounding the platter, when it comes to static electric charge build-up... | |
| static Issues...anybody know why? Geoff, as regards the skating force, you are either joking or very wrong. What happens on a blank area of vinyl is not a lot different from what happens when the stylus is tracing a groove. Friction and lack of tangency. You can call the skating f... | |
| Ceramic insulator cone under phono stage shocker! For what it’s worth, which ain’t much, the best cones I ever used were and still are the Goldmund cones that are stuffed with a damping putty. | |
| static Issues...anybody know why? The primary cause of the skating force is the friction force between the stylus and the modulated groove. A skating force is generated because of two factors: (1) the headshell offset angle, and (2) lack of tangency to the groove, which pertains e... | |
| What is the Best Tool to Measure Cartridge Azimuth? I use a now ancient Signet Cartridge Analyzer along with its companion test LP made by Shure. The SCA has a ‘scope output, but if you have no scope, it has a dB meter built onto the faceplate. So, play test LP with (usually) 1kHz test tone in on... | |
| Ceramic insulator cone under phono stage shocker! Except cones are not really inherently diode-like. We only wish they were. They can approximate the action of a diode, if very carefully placed on a resonant shelf, on areas that act like vibratory nodes. Otherwise, energy can go both ways thro... | |
| static Issues...anybody know why? Mijo, I am not sure what bone you are picking with Geoff, but the very same Shure publication you cited has a section on static. There you will find some real experimental results, some of them showing that friction between stylus and vinyl is NO... | |
| Miyajima MADAKE experience Vinyl savor, Is your D3A phono stage a current-driven type? Thx. | |
| static Issues...anybody know why? Possibly the two phono cartridges differ in the degree to which the body and/or the cantilever of the cartridge is grounded, thereby making one of them more likely to dissipate static charge vs the other. I agree with Geoff that the rubbing of th... | |
| What is the Best Tool to Measure Cartridge Azimuth? I would not recommend setting azimuth by using any combination of any bubble levels. The opportunity for error is too great. After all is said and done, it is not really a bad idea to set the cartridge visually typically using a mirror so that ... | |
| My tonearm must be wired out of phase There are two very different ways in which a stereo system can be wired out of phase. In the first case, one channel is 180° out of phase with the other. This produces some dramatic negative effects, imaging is damaged severely, and it’s just qui... |
