Don't know of any specific pre-made cables that would be up to the job, but I'd be surprised if custom / "premium" cable manufacturers would not offer options for ground lift on balanced cables. Considering your technical capabilities, just using RCA interconnects might be the best solution for you.
Low buzzing through speaks
Hello All,
Need some serious help here. So I just (upgraded?) from a Marantz AV8802A to a McIntosh MX122 preamp. I also just got brand new Revel Performa3 speaks all around (5 channel setup). I disconnect everything from the Marantz and then into the McIntosh, connect the speaks and I have a faint buzzing through all 5 speakers (that was not there previously). I have everything plugged into a Furman Elite 20pfi power conditioner which is plugged into a dedicated 20 amp circuit. My power amp is a Simaudio Titan HT200 5 channel. This is not going through the Furman but directly into the other outlet on the same 20 amp line. I even tried plugging the Sim amp into the Furman to see if that helped-no change faint buzz is still there. I have unplugged just about everything, and the buzz is still there. It is very faint and does not get louder when I turn up the volume. Again it is faint and you have to put your ear up to the speaks to hear but it is definitely there. I have tried so many things and nothing gets rid of it. It is not my cable box (I did have that issue previously with the Marantz but as soon as I unplugged the coax from the box it went away so I just bought a coax loop eliminator connected the cable to that and noise was all gone) as I unplugged that and started there.
Any help would be so sincerely appreciated????

Thank you again all for staying the course with me😊! @davidrolon thanks for sharing your issue, my router is on another floor so it’s totally separate from the system.. @russ69 @dpop just an update, the ground lift adapter and attenuator are arriving today…I’ll report back as soon as I get them and install. I am concerned about signal quality but at this point since they’re already on their way gotta try them, right?😬 |
So, @russ69 and @dpop the XLR ground lift adapters did not do anything, which I'm almost glad because wow were they a bi%$h to get in! The attenuators are arriving today via UPS. Let's see if they do anything. If not, I'm still going to try the RCA's just for kicks but that might be it (still may try the ground wire @dpop)...
Regardless as I've said this journey has been worth every second just because of all of you reaching out and taking much of your time to help and support😌... |
