| Direct drive vs belt vs rim vs idler arm Dear Lohanimal, I realize your generalizations regarding the virtues of each type of drive system are thoughtfully arrived at, but even they are open to question. I agree with the others, who agreed with me (no surprise), that execution is paramou... | |
| Direct drive vs belt vs rim vs idler arm I think of "rim drive" as a variation on the idler-drive theme, nothing to do with DD. Only, unlike the classic idlers, there is no discrete idler wheel in the energy pathway, which in my view makes rim drive more likely to transmit noise into the... | |
| Direct drive vs belt vs rim vs idler arm I agree with Viridian, execution of whatever design philosophy is the key, not the philosophy per se. Then comes the ears and brain of the listener and all the other things in life that bias us to prefer one thing vs another. (I find that I prefer... | |
| Who needs a MM cartridge type when we have MC? Dear Dover, You wrote, "rotational speed needs to be adjusted for the changing overhang as the arm transverses the record". I think what you refer to is the fact that the cutter head is like a straight-line tonearm. Thus when one is playing an LP ... | |
| Direct drive vs belt vs rim vs idler arm Zd542, You are of course entitled to your opinion, as is anyone else, but it would be well to keep your facts straight. Like it or not, in a DD turntable, the motor is not "attached" to the platter in the way you seem to think. Rather, the platter... | |
| MC cart, can I use MM phono preamp? Not to take issue with the fundamental sense of Doug's post, it is in fact also true that MM cartridges are affected by loading perhaps even more so than MC types. Most importantly, because of their much higher inductance compared to an MC, MM car... | |
| Calling all Panzerholz Aficionados I am not sure that your underlying assumption (that lots of us use Panzerholz) is valid. Panzerholz, as you know, is very expensive and very very hard, therefore hard to build with. Moreover, if one uses it to build a plinth one is not necessarily... | |
| High quality AC turntable motor Grbluen, Great question. I have been wondering the same. | |
| High quality AC turntable motor Palasr, I once wondered about modifying one of the early type PS Audio P300 power plants, such that one can attain a wider and continuous control over frequency. That plus a few other tricks might make it useable as a 2-phase controller. I think i... | |
| High quality AC turntable motor Dear Larry, I think those are two different things (splitting phase, which is an advantage for an AC synchronous motor controller, vs electrically switching speed, which can be done by either controlling voltage or AC frequency or both, depending ... | |
| Who needs a MM cartridge type when we have MC? Dear SB, You wrote, "If the cantilever's azimuth is twisted, i.e. not 90 degrees, then a more complicated diamond profile may indeed show peculiar mistracking distortions, sibilance being #1." I don't know if I agree with your assumption that sibi... | |
| High quality AC turntable motor Palasr, You are correct; the Walker MC is likely to be pretty much like the SDS. This is what I was referring to in my previous post "most" current commercial controllers do not actually split the phase of the AC.I am awaiting delivery, as I menti... | |
| Strobe question incandescent will not work, as others said or implied. | |
| High quality AC turntable motor What John wrote of the Notts controller is also largely true of the other best known tt controllers, namely that they do not do true phase splitting. Yet there are obvious benefits nevertheless. I am on the wait list for mark Kelly's controller, w... | |
| Who needs a MM cartridge type when we have MC? Obviously, story boy and I cannot both be correct. His only comment was that i am wrong. I do not see why a deviated cantilever would cause sibilance. I would rather expect it to cause distortions of other types, in one channel vs the other, or a ... |
