| Micro-ridge styli A test regime using a mono record should work. Perfect tangency would result in identical signals from each channel, exactly in phase. A signal analyzer would allow you to measure this.Of course, on a pivoting tonearm perfect tangency is still onl... | |
| Nationalism in Audio Products? My power amp:- designer was of mixed French/Japanese parentage- was built in Switzerland- was bought in Germany- was modded in New Jersey- currently uses USSR and USA tubes - is regularly biased and balanced in ConnecticutTherefore, um... | |
| Matching stepup to phono stage Richard,By empirical testing (aka lots of swapping) we ended up with Riken carbon resistors as the best sounding in our copper Mu/ZYX UNIverse/c-j PV11 setup. Second best, and cheaper for honing in on optimal values, were Kiwame carbon comps.Every... | |
| Cartridge upgrade for SME 20/2A??? Doug - a Loricraft, and a Teres 320, and a Triplanar vii, AND and ZYX Universe????? That's extreme; clearly sanity left you long ago :) You must be new around here. Everyone knows this. ;-)I hope somday to pick your brain a bit about the Loricraft... | |
| What does a vinyl record groove look like? Fatparrot,You're right, but vertical stylus movements are not a result of the groove itself moving up and down. It doesn't. Vertical stylus motions result when a different undulation is cut on one groove wall vs. the other. This differential betwe... | |
| What does a vinyl record groove look like? Mark02131,I agree that's an incredible picture. Do you know what magnification was used? What cartridge/stylus?240zracer,Sorry for not previewing my post before hitting "submit". Your words and mine got a bit tangled up. I'm waiting for a TT motor... | |
| What does a vinyl record groove look like? Inner groovewall = L channelOuter groovewall = R channelVery important to know for fine-tuning antiskate, for example. | |
| What does a vinyl record groove look like? Am I right when I say the cuts in the 90 degree sides of the groove are then 1 degree of vertical (as you look at a groove from the side)? Correct, subject to a few refinements:- different record producers used slightly different angles over the y... | |
| Cartridge upgrade for SME 20/2A??? The 17d mkII gets a wee bit confused at times when the musical load becomes really complex, so I really think it's a matter of finding a more suitable partner for my 20/2A which I believe is capable of much more. I agree your rig is worth a better... | |
| Importance of headshell and tonearm alignment It is also possible you're using the wrong protractor. The 309 was designed for different null-points than the Baerwald points used by many protractors. | |
| Matching stepup to phono stage Herman's math is correct, as is the chart on Bent Audio's page and the spreadsheet on Galibier's (Thom Mackris') site. My experience is similar to his also.Patrick's advice is good in theory but difficult to apply in real life. As Herman says, it'... | |
| In the latest The Absolute Sound Albert,I agree with Tim. - my PRC3's arm is powered; so is the arm on every other Loricraft model currently on offer - the arm is driven independently of the record groove; it traverses an ungrooved and/or non-spinning record just like a grooved a... | |
| Cartridge break in device What are the conditions that result in magnetization of a cartridge? Is it hours of playing time, months- years, both, or what?That's a controversial topic. Some argue it's impossible for any part of a cartridge save the magnets themselves to beco... | |
| Cartridge break in device Ken,Be very careful with that active de-mag unit. Many cartridge makers warn against them. Some specifically void the warranty if you use it on their cartridge. The Cardas de-mag tracks are safer (and effective IME).A device that would exercise th... | |
| Tranfiguration Orpheus description Sometimes the vocabulary we use strikes me as chunkier than the product of the fine grained adjustments it attempts to describe.Very true. Trying to express these experiences in words is quite challenging.From the above, I interpret 'a)' (integrat... |
