Who needs a MM cartridge type when we have MC?
In an MC cartridge, the stylus tip could be well aligned with the groove walls, but if the coils and magnets inside are not square to each other, I think you still could have an imbalance in cross-talk. This is a real problem, because if it occurs... 
Who needs a MM cartridge type when we have MC?
Hats off to your visual acuity. But still, the inner workings of the cartridge, hidden from direct view inside the body, play a role in selecting optimal azimuth. Perhaps this is much less of an issue with MM/MI types, because the works are partly... 
Who needs a MM cartridge type when we have MC?
Dear George,Maybe I am lucky or just live in a place with very low ambient RFI, but I never had a problem with RF pick-up that was traceable to a phono cartridge. Usually, I would blame unshielded wiring before I would blame a cartridge. Grados ar... 
Who needs a MM cartridge type when we have MC?
By "neutral" VTA, do you mean tonearm parallel to LP surface? As I noted somewhere above, I was having a real problem liking the Azden until I reduced the amount of positive VTA from "a lot" to "less than a lot". This eliminated a lot of the edgin... 
Azimuth observations and importance
Dear Doug, the OP asked how to do it with a multimeter. And that;s the question I tried to answer. Such devices do not have filters, true, but I was just trying to describe how one could do it with HIS tools, not the best way possible. Also, it is... 
Is There An "Absolute" Best Cartridge?
I am afraid that if we met in person, you guys would find out that I am a 21-year-old shapely blond female, and you would no longer pay any attention to anything I say. (Of course, if this were true, I would stay home looking at myself all the tim... 
Who needs a MM cartridge type when we have MC?
Dave, Where are you setting VTA? How did you set azimuth, by ear or by electronic means? Thanks. 
Azimuth observations and importance
Ideally, you would measure the voltage output where the cartridge attaches to the phono stage. This is really unlikely to work well for the unamplified signal direct from a LOMC cartridge, so the next best thing would be to measure the voltage at ... 
Azimuth observations and importance
I think this is what it boils down to. Please anyone correct me if I am off base:(1) You need a test LP that has a band where signal of a known frequency is recorded for one channel only. Lets say it's the R channel. Play the band and measure V in... 
Who needs a MM cartridge type when we have MC?
What that guy is doing with his ohmmeter (to demonstrate the internal resistance of the cartridge) is a bit dangerous for an MC. The current put out by certain meters can fry the coils of a delicate MC. Probably it's OK in this case, since the obs... 
Rhea Noise
Dear everyone including Raul, I am so sorry. I had no idea how old that post was, until I actually looked at the date as a result of Doug's comment. 
want new plinth ideas for direct-drive turntables
Thanks for sharing. That's really nice work. You can see a rather poor photo of my slate Lenco in my system post here on Audiogon. Plinth is a monoblock of slate, unlike yours. Used Peter Reinder's top plate. Probably should post it in Lenco Heave... 
want new plinth ideas for direct-drive turntables
Hiho, Don't own either SP15 or SP25. I was just conjecturing. If I do it, it would be with the SP10 Mk2. Have you made a template for the cut-out for a Mk2 motor? 
Azimuth observations and importance
Dear Dr. Cilantro,What Doug said. Azimuth is about crosstalk between channels, the amount of the signal in the L channel that appears in the R channel, and vice-versa. It is not about channel balance. In fact, even at extremes of azimuth, the volt... 
want new plinth ideas for direct-drive turntables
Hiho, What about the SP15 and SP25? How do those compare to the ones you listed above as donor tables? They are way less expensive than any SP10. You guys got me thinking (again) about separating the SP10 Mk2 motor from its chassis and on-board el...
