| Noise reduction -why the rage now ? So the signal magically appears at the speaker terminals, passing right over our electronics. That means delta-sigma DACs don’t affect the signal (sound different than R2Rs) etc. Thanks for the laugh. | |
| Noise reduction -why the rage now ? Geoff -I thought the wave carried the signal. Then, as far as RF damage -does it delay or ’erase’ the wave (or signal) ? Some links/studies would help.And thanks snapsc, love those measurements. Esp how modern SS amps still heat up !! | |
| Noise reduction -why the rage now ? Well, your 10 paragraph response probably threw me off. All I’m saying is we cannot hear RF (directly), as it shoots through the air, in audio circuits. BUT I admit, it’s still a problem as it gets conducted by all that metal (in a component). Hen... | |
| Noise reduction -why the rage now ? You were hearing something else. The science says we cannot hear RF directly. But as I described above, it could be getting into the circuits and getting amplified. | |
| Noise reduction -why the rage now ? Microphony is different issue. RF can be "overcome" IF you use a very-advanced technique like the Nordost QPoint (just demo’ed at RMAF ’19). But it’s still best to SHIELD parts from RF, rather than "overpower" it in the air... | |
| Noise reduction -why the rage now ? Thanks for sharing this. I believe power cords should be shielded. Co. that make (expensive) after-market ones say this. No power supply is quiet, unless you can prove the rectifier & regulator produce zero noise. Most rectifiers were putting ... | |
| Noise reduction -why the rage now ? RF is not very high-frequency -megahertz and gigahertz ranges are. And that’s where consumer-stuff is going, to a much quieter region of energy.Then, there’s no evidence to support the "worsening effects" of RF (as the link explained). True, if yo... | |
| Noise reduction -why the rage now ? You didn’t read the whole article. "The bottom line is no-one really knows whether outdoor noise has increased or decreased in recent years. And the same goes for measurements made indoors."Later says "the needed data is almost totally missing".Ye... | |
| Noise reduction -why the rage now ? Here is something very interesting. We DON'T KNOW if noise is worse in recent decades, at least with RF.I can’t seem to add the URL, so type:"electronic noise is drowning out the internet of things ieee.org" | |
| Noise reduction -why the rage now ? Would LOVE to know what percent of noise is coming from::Our playback gearDC motors, dimmers, WiFi in our houseThe grid - neighborhood noise, radio stations, etc.THEN to know how much total noise (in db) there is... | |
| Noise reduction -why the rage now ? I don’t think SMPS are noisy, today. In the past, we had poorly-designed ones (in high-end audio) and I’m sure of that. Most co. still use LPS, at least with line-level components. They use cutting-edge regulators (like Hynes) and are a success.So... | |
| what is it in audio that you dislike most? High price, low science. Always a problem, though it seems to be slowing down. More science, lower prices -R2R DACs, signal wire, waveguide/horn speakers, subwoofers, etc.Reviewers that do it wrong. Use a speaker with (1) amp, a room too small for... | |
| What’s really hurting the audio hobby? Glennewdick: what are the (6) brands that you see worldwide ? I’m shocked, as there are hundreds available.Geoffkait: AA still swings-in w/ 30,000+ hits and other places like AudioShark are growing every year.Based on the comments here, audio is n... | |
| The term "High End" needs to die. Long live Hi-Fidelity! I'm clearly referring to playback... | |
| The term "High End" needs to die. Long live Hi-Fidelity! The term also associates with the 70s. Panel speakers and (the slow) return of tubes. In short, backwards technology. Yes, solid-state had problems. But if more people tried to figure it out (like Quad and Pass), instead of going the easy-path of ... |
