I’ve talked to the folks at Crutchfield and Emotiva and they basically said if it’s that low and you can’t hear it from the listening position to just live with it as it’s not something worth going crazy over. You really have to put your ear within about 4-6 inches of the tweeter to hear it…🤷♂️
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 @russ69, but how as they are coax? I don’t have a way to connect it between amp and preamp? |
If the Titan is more than 15 years old, there could be a possibility the power supply filtering capacitors causing the noise. You can disconnect all the input cables from the Titan, power it up and see if you can still hear the buzzing noise. |
Thanks @imhififan It is more than 15 years old but I sent it to Simaudio for “calibration and cleanup” last year and she came back squeaky clean. They actually said she was in better shape than most-though they said they don’t see many of them because they “overbuild their amps”. I’ll give that a shot. Like I’ve been told it’s a minimal buzz that you really have to get your ear up to within a few inches of the tweeter to hear, but it wasn’t there before so that’s why I’m totally perplexed. I should also mention that when I switched out the Marantz for the McIntosh I totally switched up my setup which means cables and power cords are all intertwined. This also might be causing it im told? It’s always been spaghetti ills but now IC cables and power cords have changed logistics… |
