Would this also be suitable to use to power my cable internet modem and router?
What's the problem with your present power supply/s for your cable internet modem and router?
Sounds like a load of bollocks to me. Telecoms equipment like that uses switch-mode wall warts these days, usually double-insulated with no PE contact at all, and as long as live and neutral are connected, these will work fine with little regard to mains quality, even on all DC - they need a DC isolator about as much as a hole in the, erm, case.nothing really except that I read someone’s review online that said they swapped out their power strip that powers their cable modem and router and now when streaming music it sounded much better, compared to the power strip they were using which was and is the same one i am using right now, which is the furman pst-8d.
I believe them because I tried plugging my HomePod into this strip before and it made all music sound robotic like and just not enjoyable to listen to. I ended up plugging my HomePod to the less expensive furman pst-6 that does not feature some of the more advanced filtration and protection technologies furman advertises and music sounds just fine.
Audiophiles write things like that all the time. But their posts lack due diligence and they never support their comments.nothing really except that I read someone’s review online that said they swapped out their power strip that powers their cable modem and router and now when streaming music it sounded much better
Why not? OTOH, I prefer to use a small UPS for modem and router to avoid resets due to the occasional voltage sag or interruption.
P.S.: I use the CMX-2 on my OLED display.
I have a Heed Obelisk Si MK3. I have been experiencing intermittent transformer humming from this amp. This is a mechanical hum from the amp itself. It does not present in the speakers or pre out of the amp.
I tested the amp with all the circuits off in my house except one, on which the only thing plugged in was my amp. I still encountered the humming sound.
I sent it in for service and the techs reported that the amp was silent and in perfect condition. A colleague mentioned I might have a DC offset issue in my ac line which could cause the toroidal transformer to hum.
I purchased an emotiva cmx-2 and my amp is now completely silent. There is no longer any noise coming from the amp at all. Problem solved.
I purchased a Van Alstine DC blocker rather than the Emotiva, but my experience is otherwise the same as yours. My power amp, an Adcom GFA-5400, would exhibit a low-volume (but audible from my listening position during moments of total silence between songs) hum. Per many online descriptions of the effect of DC offset on toroidal transformers, the hum would slowly build, and then get quieter, and then slowly build again, in a cyclical fashion.
I tried all the troubleshooting measures you describe and more, and confirmed that it was a mechanical sound from the enormous toroidal transformer inside the amp, which did not transmit through the speakers and was unaffected by the presence or absence of any other equipment in my system or home. The DC blocker fixed the issue - no more hum.
