Excellent Power Supply Solution
The ifi wall warts are in about the same price range, and extremely well reviewed for both measured and audible performance. They replaced my Astron. They don't have nearly 10A of output though. :) https://amzn.to/3n4W0xs Best, Erik |
With the iFi DC power supplies, you have to be careful with the amp rating. It’s OK for a power supply to have a higher amp rating than your device. But it cannot have a lower amp value. The same is true for the wattage. The 12 volt iFi power supply only handles 1.8 amps. Many of the cable modems and routers require more than 1.8 amps. That’s why the Waveform Lighting power supply worked so well for me. I just ordered another one today. While I’m at it, here is another tip. I wanted to put a high grade AC power cord on this power supply, but the ones I have do not have C7 connectors. Fortunately, you can order a C7 adapter from Voodoo Cable for $19.00. The non-polarized type works for most routers and modems. Here is the link: https://voodoocable.net/product/c14-to-c7-iec-two-pin-adapter/ |
First, I work at Broadcom switching products, so I do know what I am talking about. Home routers & switches work at giga hertz frequencies and speed, which are WAY over ANY audio signals you are listening to especially if they are hard wired (ethernet), rather than using 11ac or 11ax wifi (which, depending on whether you are running at 2.4G band or the 5G band MAY be subject to collisions and may likely be a bit slower as a result). The basic supply that comes with all boxes are absolutely fine. Since those work great even at frequencies 1000 times higher than your audio and still working perfectly fine, what you are noticing is nothing but the placebo effect. Do not waste your money on snake oil. |

<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>> So you're the one that made the noisy PS? Is that what you're saying. Or you know how to fix them? Which one is it? What about Laptops, with noisy PS, some are REALLY noisy, what's the fix? Placebo? Snake Oil, one is noisy, one is not. Am I missing something? Regards, |
It is common knowledge in the audio world that standard switching power supplies (wall warts) inject noise into the AC power line. This is not necessarily a noticeable hum. It is a type of interference that can degrade an audio signal. It is not the electronics within a router or a modem that causes this problem. It is in the lower grade power supplies. This is the reason for putting expensive linear power supplies with music streamers and other audio components. No one is required to believe this, anymore than they are required to except the findings of Charles Darwin. It is simply something to consider if you want your audio equipment to sound its best. Happy listening! |
