| Correct Input Sensitivity Setting for Cartridge Just to be clear, we are talking about the output of the cartridge in terms of its signal voltage. We are not talking about the input sensitivity of a cartridge, which is a term that almost makes no sense. Sorry for being pedantic, but if you want... | |
| Next upgrade for my analog source Or, you can subconsciously select speakers that compensate for your room problems. That isn't so crazy, because no room is ever perfect, and even if you have a good room, you eventually will have selected speakers that work well in it. That said,... | |
| How often to demagnetize mc cartridges? I don't know how the cartridges on your extensive list are made. Except for the ART7, which I do know has an amorphous core coil. I think that one contains no iron, no magnetic materials, does not need fluxbusting ever. MM cartridges, of course,... | |
| Direct Drive vs. Idler Drive vs. Belt drive Problems with two or three motors are: (1) They have to be perfectly in synch with one another, and (2) you now have two (or three) potential sources of noise that could be transmitted via the belt to the platter. No free lunch. I also think tha... | |
| Next upgrade for my analog source I hope it came through that one absolutely cannot use a current Drive phono stage with a moving magnet cartridge. Only a select few moving coil cartridges that have particularly low internal resistance and low voltage output can be used advantageo... | |
| Direct Drive vs. Idler Drive vs. Belt drive Mijostyn, have you had direct communication with techdas and clearaudio? I was wondering how you would know the basis for their marketing decisions. I don’t know about techdas but in my opinion clearaudio is a company that does not really make any... | |
| How often to demagnetize mc cartridges? Depends on how the coils are constructed. If iron core, the core can be magnetized. Then an occasional hit with flux buster is worth doing. But not very often. | |
| 2020 update : JC Verdier La Platine I too have owned two Luminescence’s. Never had a problem.However it is a complex circuit, and it would be impossible to guess from a distance wgat might be going wrong with yours. If Scott Franklin is still alive and well, he is the obvious choice... | |
| Direct Drive vs. Idler Drive vs. Belt drive Thanks, Ralph. That's a very key point about direct drive (the absence of a force in the horizontal plane that pulls the spindle shaft up against the bearing wall) that the belt-ers choose to ignore. | |
| Direct Drive vs. Idler Drive vs. Belt drive Mijostyn, If you have a recording of fingernails on a chalk board, any good Technics table will make it sound like fingernails on a chalk board. But why do you want to listen to that? | |
| Direct Drive vs. Idler Drive vs. Belt drive Tom, I liked your list of 16 yes or no alternative preferences. I calculate that makes for 65536 choices in turntables. (2E16) | |
| Fidelity Research FR64s Headshell dilemma Bukanona, I am still not quite sure I understand your point. Surely you would agree that Euclid, Pythagorus, and the rest have left us enough formulae to deal with any nuance of tonearm alignment. If you consult the original papers by Baerwald a... | |
| My record player sounds slightly high pitched If the belt is or was slipping, I would have guessed that the music might sound "flat" or slightly lower in frequency in other words. Not "high pitched". I suspect that the turntable may be running too fast, at a speed greater than 33.33 rpm. To... | |
| Fidelity Research FR64s Headshell dilemma bukanona, What do you want to measure, tracking angle error or the distortion that results? The former is completely predictable using geometry handed to us by the Greeks and their mathematical descendants. The latter is complex, because you wou... | |
| Cartridge azimuth adjustment using a voltmeter and a test lp mrubey, Most cognoscenti (and I don't count myself as one) would say that using a mono LP is not the way to adjust azimuth. Centering the image is mostly the result of achieving equal channel balance, and the goal of azimuth adjustment is to mini... |
