| Ground loop with Miyajima Premium mono Here's a question: Is there any difference at all between the "BE" version and the plain Premium version, other than the species of the wood that is used? Miyajima website says nothing to indicate any other difference. A US vendor says there are i... | |
| Ground loop with Miyajima Premium mono Whoops!!!! I was wrong indeed. I looked on the Miyajima website, where it says, "When it played a stereo LP with this cartridge, a sound is that a distortion and a needle do not work lengthwise, and there is the thing that a needle injures the dit... | |
| Ground loop with Miyajima Premium mono Salectric, I know nothing about this subject (whether and why a mono cartridge could damage a stereo LP), but just empirically it seems to me that any cartridge with a conventional cantilever has "vertical compliance" to one degree or another. Wha... | |
| Using a DD table as motor to drive another table One of the benefits of driving one platter with another is reduction of belt creep, and if you do it with a thread, there are fewer of the other issues associated with BD. Everyone who does this swears by it, but we all swear by all the things we ... | |
| Ground loop with Miyajima Premium mono Thanks, Ralph. I had the suspicion that this was the case, but actually forgot to mention it in my post. But, hum is hum and must be eliminated when possible.It would not surprise me to learn that the hum issue has much more to do with the circuit... | |
| Ground loop with Miyajima Premium mono My phono and line stages are fully balanced, so perhaps this would not be an issue for me. Balanced lines typically are less subject to ground loop problems (he said, with his fingers crossed). I would not want to have to build a Y-connector using... | |
| Ground loop with Miyajima Premium mono Robin, Do you mean to say that this is the usual recommended mode of operation for the Premium mono (one channel hooked up and preamp set to "mono")? Does this mean that one would have to tolerate hum (or sound coming out of only one spkr) if one'... | |
| Turntable speed accuracy If you take a look at one of the old brochures for the Denon DP80 (I think), they present an actual plot of instantaneous speed v time. The DP80 is not perfect in this graph, but Denon claim it was superior to the un-named competition. This is rea... | |
| Tweaks such as demagnetizers ionizers for lp's Dear Rushton, when you say it works, what could possibly be happening that improves LPs, CDs, cables, and most of all speakers!? (we do know that cone speakers depend upon magnets in order to work. You don't want to demagnetize them.) I have great... | |
| Turntable speed accuracy My mistake, Thuchan. So therefore the allnic and the timekeeper would be about the same. I thought I had read elsewhere that the allnic light needs to be plugged in to AC. | |
| Denon DP-72L What is phono gain of your phono stage? I am guessing it is suitable for mm/mi cartridge (high output) but not for low output cartridges (less than 1mV). So choose a cartridge based on that. Most mm or mi cartridges are high compliance. So choose ... | |
| Turntable speed accuracy Accuracy or sensitivity of speed monitor device should be proportional to (1) distance of sensor from center of rotate (longer radius is better) and (2) stability of the strobe at 60 hz per second. Ergo in theory the kab strobe (battery powered an... | |
| Turntable speed accuracy Bearing lube for dd turntables is yet another controversial subject. Fortunately, the rotation is so slow and relatively low stress that almost anything will do to prevent bearing damage. One guy who restored my L07D insists on only a certain weig... | |
| alternative power supply for Garrard 301 I read my own earlier post above, and I don't know what I was thinking. My own experience with lenco motor (similar to garrad) and mark kelly's teaching both tell me that controllers designed for ac synchronous motor (walker, vpi Sds, notts wave) ... | |
| Turntable speed accuracy It seems like none of us read each other's posts, except Raul and DT, so that they can reach immediate disagreement. A century ago an American writer named Ambrose Bierce defined "conversation" as a social interaction wherein I wait for you to fin... |
