| CD Player? PC Music? Naaa Flash Memory Music. Why flash drives, not CD’s? Because the big problem with the Digital Music is one thing called jitter. And with this solution you throw away the major source of problems in this matter. Optical drives and their Digital MASTER internal clock’s.Whil... | |
| Ground Cheater plug or.... The hum remains even if the ICs are disconnected from the amp. Then the hum is most likely not being caused by a ground loop, and it most likely would not be fixed by either a cheater plug or by disconnecting the safety ground inside the outlet.Th... | |
| AIFF vs Apple Lossless Ripping Thanks, Kijanki. Concerning sonic differences between lossless audio formats, see my thoughts here, and in my subsequent posts in that thread. Note also the posts in that thread by Steve N. (Audioengr), who offers some alternative ideas.Best regar... | |
| Shielding components from EMI/RFI... Help please I can't explain it either, Kijanki. I was just reporting what someone with a strong technical background and a distinguished track record designing this kind of stuff has said. It wouldn't surprise me if he couldn't explain it, either.One speculat... | |
| Favorite 300B: Sophia vs KR 03-28-12: Charles1dadThe VAC REN amplifiers have auto bias, would`nt that compensate(at least somewhat) to the various ma levels?Yes, to a considerable degree. Also, the bias conditions that the amp is designed to automatically establish are most ... | |
| Shielding components from EMI/RFI... Help please I also tried ferrites on the S/PDIF cable connecting the Sonos and the reclocker. That sounded bad. It made things sound hard and glassy. I suppose it elevated jitter.Yes, putting ferrites on digital signals for which jitter may be an issue is und... | |
| Does the Quality of the USB cable matter? Ed, what kind of interface do you have between the MacMini and your DAC (USB, ethernet, S/PDIF, etc.)? And how much distance is there between the firewire cable and the DAC (and its cabling), as well as between the firewire cable and the rest of t... | |
| Favorite 300B: Sophia vs KR Paul, yes "ma" stands for milliamperes, and in this case refers to the plate current under some given test conditions (plate voltage and grid-to-cathode bias voltage particularly; perhaps also filament voltage if that is varied from its nominal 5 ... | |
| preamp out instead of MC transformer Equalizers and other processors were, and sometimes still are, generally inserted into tape loops, which places them "before" the volume control. In some situations it might also be appropriate to insert a processor between preamp and power amp, o... | |
| Favorite 300B: Sophia vs KR Michael, I would definitely avoid the 80 ma tubes, on the basis of Kevin's indication that they might trigger the amp's self-protection mechanisms. I'm a little uncertain about the 48's as well, especially given that we don't know the measurement ... | |
| preamp out instead of MC transformer The idea of running it out of the preamp out to the mm preamp and back into the preamp in of the same preamp is to use the MM preamp like an outboard processor, much like people used to do with equalizers and such in the past. I didnt meann to imp... | |
| preamp out instead of MC transformer Not sure why you said "back into the preamp in." To have any chance of working, it seems to me that the output of the second preamp would have to go to the power amp.Given that, while it is conceivable to me that the idea might work with certain c... | |
| Intermittent channel in TT setup - ideas? Yes, that's all pretty vexing. An intermittent phono cable connection could conceivably affect the noise floor in several ways, although one of those ways would affect it in the opposite direction from what you observed. First, if the connection o... | |
| VAC Owners:Outboard Phono Stage? 03-25-12: AlonskiIt seems clear and obvious (well, now) that "direct" is not possible because with any outboard or built in phono stage, one would need a volume control and additional circuitry to control the downstream amp, in essence, you need a... | |
| Shielding components from EMI/RFI... Help please Bryon, an additional point occurs to me regarding the ERS cloth. Since its core is somewhat conductive, if it is placed close to circuitry (significantly closer than the metallic structural surfaces of the component), its presence could affect the... |
