"Arny Krueger" wrote in message news snip, irrelevant to point below I was spinning vinyl back in the days when the first elliptical styli came out. Lots of us upgraded existing cartridges to use them, even though our existing conicals were in good shape. I agree with Arny on this. Ellipticals were a godsend and greatly improved tracking, improved high-frequency sound, and reduced surface noise. There was a mass migration and upgrade as a result. When finelines came along, they carried this further but the improvment was incremental, not massive. |

"Arny Krueger" wrote in message ... Conical styli are generally a step backwards. So we have a big step backwards into an obsolete format, followed by a step backwards within the technology of that obsolete format. Pretty much sums it up. But at least he admits it's only to save money (even that's doubtful) not that it's actually superior to CD, as many others feel the need to claim. MrT. |

A conical stylus is symmetrical. It can be a little twisted one way or the other and it still contacts the groove the same. Not so, there are three axis that need to be aligned. Maybe the horizontal plane will not affect a spherical tip, but the vertical plane and tracking angle still have an effect, unless the stylus was a complete sphere. Alignment does NOT stay the same. If you use your turntable regularly, things move around as you handle the tonearm. Elliptical stylii need to be aligned every three to six months with everyday use. Yet my experience over some decades of using LP replay systems with non-'conical' styli did not agree with your theory. Although it has been some time since I used LP on an 'everyday' basis. But I did do so for many years. Doesn't match many others experience either. Maybe he is very heavy handed. For all I know, you are correct. But I haven't found any assessable evidence, not have you provided any, nor does my experience indicate that you are right. So unless you are able to provide some specific reference that I - and perhaps others - could examine, I am afraid I will have to doubt your assertion. :-) Given his lack of understanding of the alignment procedure, I would say that is a wise move.

Sorry. You're the one who hasn't been listening. That isn't what I said at all. Are you trying to prop up a straw man? I notice you snipped the part where I suggested any doubters merely use Google groups to ascertain that is pretty much exactly what was claimed. The thing I love about Usenet is that anybody can claim they didn't say something, but the whole world can still read exactly what was said. If you are now making a different claim, maybe you should tell us what it is? MrT. |

See ya Steve If the cartridge is properly secured in place, the alignment should not change with ordinary handling. This seems obvious. In the under - 50.00 range, the Grado Prestige Black is a stone bargain. Mark Z. |

The fundamental arm/stylus resonance is more like 8-12 Hz, not 15 kHz. Playing it at half speed then converting to normal would move for example, into the 16-24 Hz region. |

Yes, but since you are only copying to a computer, then it may not matter all that much. Any artefacts below 30Hz can be filtered out, (usually nothing below that on the record), and you needn't use monitor speakers, or even stay in the room, so physical vibration induced problems will not be so much of an issue. However it would require the TT/cartridge system to have a relatively flat response to 15 or 20 Hz, (to get 30 or 40Hz) which is not so easy to achieve IME. I also wonder just what benefits would be expected, since a good system can play all the treble available on any record at normal speed, and the biggest problem in many cases is in the bass region. Might be better to increase the playback speed instead. MrT. |

"Stephen Worth" wrote in message ... I said that it's perfectly possible to put together a good sounding setup for playing vinyl LPs for $250 to $300. Lets see you said : Dual 1228 ($75 to $100) Used 70s preamp with phono input ($40) New cartridge ($50) OK so far, (depending on your definition of good sounding of course) assuming you can actually find a Dual 1228 for that price. Just add a new belt, and possibly replace motor, spindle and arm bearings :-) (assuming you can actually get them) Good S/H Duals are pretty thin on the ground around these parts though unfortunately. Tell us what NEW $300 turntable/arm/cartridge you consider good sounding with minimal record wear? I guess we should all trade our expensive TT's in on the cheapest Pro-ject, which is the only thing I know that even comes close to your price. Having heard one, I won't be trading mine any time soon! You also said : "A $50 conical/spherical tip cartridge is kinder to records than the most expensive elliptical, and it's a lot easier to keep in proper alignment." Which is what I objected to. Current denial that you even said it, and lack of supporting evidence on your part is noted. Your misunderstanding about cartridge alignment is also noted. MrT. |

Play a LP at half speed and bring up to playback pitch, and they are now in the 12-24 Hz range. Remember, that's the center frequency of the resonance. Tone arm resonances are moderately damped, so their effects afflict several octaves. |

However it would require the TT/cartridge system to have a relatively flat response to 15 or 20 Hz, (to get 30 or 40Hz) which is not so easy to achieve IME. The mechanical system consisting of the tone arm effective mass and the stylus compliance forms a second order mechanical resonant system. As such, that means it's a second-order high-pass filter with the cutoff frequency corresponding to the resonant frequency. Pplaying an LP at half speed,a s one example, means that ALL the information is shifted down one octave. But that mechanical high-pass filter remains the same. Thus, the effect, once the half-speed play is compensated for, is to have that high-pass filter move up an octave. That means that, under the somewhat optimistic assumption that the resonance is damped enough to give a Butterworth high-pass at, oh, 12 Hz, playing at half speed and compensating makes it a high-pass at 24 Hz. In fact, the vast majority of turntable systems I examined over the years were seriously UNDERdamped, with effective Q's in the realm of 2-5, which meant a pretty sizeable peak (in the range of +6 to +14 dB) at resonance (12 Hz). Now, move that peak to 24 Hz, and we begin to see the problem. Now, for sure, the response is minimum-phase, and can be completely compensated for by a complementary equalizer, but there are several issues: 1. How many people know, with reasonablt certainty, precisely what the resonant frequency of the arm/ cartridge system REALLY is, and what is REALLY the system Q at resonance? (hint: almost none) 2. Regardless of whether it is equalizable (it is), what you have done by shifting all the audio down by low- speed playing is that you have now placed it in the realm of that (likely) under-damped resonance. Now you face the problem that you have significantly MORE signal to stimulate that resonance and, being under- damped, increase the likelihood of potential mis- tracking problems, rather than decreasing it. I also wonder just what benefits would be expected, since a good system can play all the treble available on any record at normal speed, and the biggest problem in many cases is in the bass region. Might be better to increase the playback speed instead. But you trade one set of problems for another. Rather, IF people would take the time and effort (and it's NOT easy) to make sure the arm cartidge resonance is both at the right frequency AND has a Q in the realm of about 0.6 to 0.8, then things will be fine. The problem is that the normal practice of applying some indiscriminant amount of damping goo DOES NOT WORK. The ONLY way to do it is to apply the right amount of the right jind of damping, and the ONLY way to do THAT is to MEASURE the result with appropriate test equipment. I have, in fact, done that and when properly done, results in even rather "ordinary" LP playback equipment being able to track damned near anything and, by the way, also reduces isolation problems (an underdamped arm/cartridge system is more prone to isolation issues, because you have more gain at the resonant frequency, partically defeating the low-pass filtering effect of the turntable suspension). And, for those of you out there eager to jump in an tell me that their tone arm IS properly damped and all, please, spare me the waste of time. Of the many hundreds of turntables examined, ranging to the most esoteric, I never saw ONE that was even close to the proper Q. |

It doesn't make sense to buy new turntables for so much money, when there are so many excellent used ones from the 70s that offer so much more value for the money. I agree, and it doesn't make sense to buy a turntable at all when CD players offer "so much more value for the money" than any turntable. Except of course to transcribe old records you have in your collection. Most people with a record collection will already have an old turntable though. Those that god rid of their TT usually got rid of their record collection too. You're just arguing for arguing's sake. Not at all, I STILL don't think a $50 cartridge is the equal of any CD player. You know all this stuff already. Yes, the bit's that are actually correct anyway. MrT. |
