| Speed Stability Very true. Eccentric rotation alternately accelerates and decelerates the velocity of the groove past the stylus. Varying groove velocities necessarily cause pitch variations, think Doppler effect. These variations may or may not be audible depend... | |
| Choosing a new turntable If you can stretch to $4K, consider the Galibier Serac with the $750 arm of your choice. - major step up at an attractive price- small (albeit tall) footprint- accommodates any tonearm you choose, now or in the future | |
| One Step Record Cleaner Recipe Jimateo,You've looked at all the recipes you could find and are still confused, so I conclude you're not a scientist. IOW, like me, you're not particularly well qualified to DIY in this area.Why not buy a product developed and tested by people who... | |
| Speed Stability Jeff L,We didn't take any photos. You might find them online somewhere. Remember I was talking about RMAF 2008, not 2009.Tony,Further to what Mosin said, speed variations occur over every possible time span, from the length of an entire LP side to... | |
| Vinyl "bleed through"- need set-up advice Dusty,Good example, and there are many throughout that song. The one you mentioned is so huge it's often audible over the radio. Many LP's have a pre-echo in the lead-in groove, especially if the opening chord is loud, as you said.A stiffer test o... | |
| Vinyl "bleed through"- need set-up advice With respect to Polk432, if adjusting your cartridge reduced pre-echo then I believe you somehow adjusted it farther from optimal rather than closer to. Not saying your alignment isn't better, since the Mint is superb. But you may have inadvertent... | |
| Speed Stability Andrew,Here's a link to that LP (don't know anything about this seller, just an an example). One of our nicer sets is a massive Erato box containing all of Vivaldi's opus-numbered sonatas and concertos, from I-XII, with I Solisti Veneti/Claudio S... | |
| Speed Stability Hi Andrew,That cartridge was in the unnamed third room, which I won't identify here. We learned that lesson! (It wasn't a Tranny of course. Your Orpheus would shame it, though the other cart costs far more.)I can't compare the Saskia and TW AC dir... | |
| Speed Stability I'll support Frogman's general assertion, both from theory and from my own listening experiences and Paul's. All turntables exhibit speed instability. There are no exceptions, only differences in degree and kind. When a mechanical drive system is ... | |
| About Lugnut -- Patrick Malone Nate,Thank you for bringing this thread back to the fore. The holidays may have passed, but any time is a good time to remind ourselves of the value of friends. I don't even have to read the thread to feel tears well up, the memories are strong.Pa... | |
| JMW 10.5 vs SME V Jkorten,Impressive report. I don't even have an SME arm, but it was still a good read. Wouldn't a conical spring (wide end on the piston) or a full-width spring somewhat mitigate the possibility of canting? I'll bet that's what SME thought. (Of co... | |
| Exactly where is the pivot point of Dynavector 507 I've never used a Feickert for cartridge overhang/zenith adjustment, since other tools are better, so I can't answer your question.If you have a Mint protractor, use that and forget the Feickert disc. | |
| Automatic Cueing and Automatic Return :-)In a sufficiently resolving system, EVERYTHING is audible, including extra doo-dads attached to the plinth or (especially) the tonearm. I've removed various unneeded bits from my TriPlanar arm because its sound floor is lower without them. Whet... | |
| Exactly where is the pivot point of Dynavector 507 I've posted this before but here it is again:1. Make a tiny dot with a fine point pen on a small piece of Scotch tape. The tinier the dot, the better.2. Stick the tape on top of the bearing housing, with the dot directly above where you *think* th... | |
| Mylar tape on Teres has lots of static. I am thinking that the static is caused by the belt slipping on the motor pulley at start up. Start your platter manually with a finger push, not by pushing the motor's "On" button. Less belt slippage and wear, less strain on the motor, more fun s... |
