| VTF and VTA- Constant or not? Dan, Since record company cutting head VTA's are known to have varied from a low of around 15 degrees to 20 or even 22 degrees, Dertonarm's suggested range seems reasonable. I haven't gone that far myself, but I can confirm that there is great con... | |
| VTF and VTA- Constant or not? What would happen to the data on your post-it notes if you changed arm, cartridge, or table? This thought has always kept me from adopting a similar system.Quite right, Tom. Each data point is rendered obsolete by such changes, and by some others ... | |
| Arm geometry and null points Henry, Still not sure why you had to ask moi in particular, but thanks for clarifying. Yes, you can use the Mint's null grids after setting S2P and overhang by other means. As Mark noted and you obviously understand, the Mint's arc won't be useful... | |
| Koetsu Coralstone vs Olympos or Universe? Agree with Syntax that Koetsu/TriPlanar is not the best match. I'm no fan of the classic Koetsu sound, which always sounds artificially smoothed to me. This is true of every model up through the Onyx Platinum (haven't heard the Coral). The stone b... | |
| VTF and VTA- Constant or not? It's unlikely any "topnotch" audio system could come close to live, acoustic instruments, so I agree that would be a poor yardstick. I haven't personally heard any digital that matches our vinyl, though to be fair our vinyl front end cost more tha... | |
| Arm geometry and null points Null points (Baerwald and otherwise) are defined by measuring a specified distance along a radius centered on the TT spindle. The tonearm has nothing to do with their location.Null points do not change whether you adjust spindle-to-pivot or overha... | |
| VTF and VTA- Constant or not? What's your best, quickest method to prove that VTF and VTA/SRA have been set up correctly or close to ideal?"Prove"? Hmmm, I doubt the concept of proof is practical in this context. One could prove these things with lab equipment and a frequency ... | |
| 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... |
