| Turntable Mats for Technics Grand Class, "G" Series I don't disagree with anything you wrote about the desired function of a mat, but my question was why does the mat have to be glued to the platter? The glue itself forms a boundary between the mat and the platter, which may or may not reflect ene... | |
| A Question: What makes for Good Vinyl? My own experience is different. I’ve got many LPs based on digital masters that sound fantastic. And I’m somewhat phobic about digital. | |
| New Sugar Cube is picking up hum from phono stage What cleeds said, plus have you tried disconnecting the ground wire between components? And obviously check the cartridge grounds. Both channels? | |
| Turntable Mats for Technics Grand Class, "G" Series I own or have owned a DP80 and Technics SP10 Mk2, 2a, and 3. What do you find to be so different among the rubber mats supplied with those TTs that would lead you to conclude that the Denon DP80 mat is superior to the Technics mats? I didn't hear ... | |
| Turntable Mats for Technics Grand Class, "G" Series Why does the mat have to be glued to the platter? Seems to me you’re better off with nothing between mat and platter, for best energy transfer. If the mat slips in the absence of glue, I’d consider a record clamp or weight to push the mat down fro... | |

| Phono Box DS3 B output impedance Found this quote from the late Al Margolis, who was either an EE or a physicist and who was in any case brilliant, on the "cables" forum in 2009: "Characteristic impedance, being part of what are called "transmission line effects," is (at least f... | |
| Ikeda 9tt retipping In any event, I agree with you that Boron is probably superior. I think my Ortofon MC2000 cartridge, which is admittedly early 1990s state of the art, also has a duralumin(um?) cantilever, yet it sounds pretty great if you have enough gain. | |
| Phono Box DS3 B output impedance They are talking about "characteristic impedance". Whether that matters at audio frequencies and with typical 3 to 6 foot long ICs is the question. The more I read about it, the more I am convinced it does not matter. Here is a practical rationale... | |
| How often to you clean vinyl and the needle? Those vibration based cleaners do work nicely, but they are not "ultrasonic". The ones I know about, sold under the Audioquest brand and maybe some others, vibrate at around 500Hz. That's why you can hear it. I have the Audioquest version but u... | |
| Ikeda 9tt retipping "Duralumin" is an aluminum/copper alloy. Not pure aluminum. Probably a step or two up from pure aluminum in cantilevers. | |
| 12" Schick Armboard Specifications For me, the failsafe method is to have the blank board made and fitted to the TT. Then using a gauge of whatever kind that fits over the spindle, measure the distance from the centerline of the spindle to the centerline of where you want a hole d... | |
| Phono Box DS3 B output impedance The jury is still out on whether the "impedance" of the cable, which when we say it is 50 or 75 ohms for a single-ended cable (with RCA terminations) or 110 ohms for a balanced cable terminated in XLRs, should be added in, in calculating the ratio... | |
| Phono Box DS3 B output impedance "How can you not know this and still spout all kinds of technical details here?" Because I only write what I think is correct. However, I am not an engineer, not infallible, and I can make mistakes. When I am in the wrong, I like to be corrected... | |
| Phono Box DS3 B output impedance Where on earth do you get the idea that "an XLR cable" has a 110 ohm impedance? And even if it did, do you count that as part of the output Z or does it add to the input Z? That choice would drastically affect the calculation. Of course, the highe... |
