Low buzzing through speaks

Thank you @willgolf! Just read your reply went right to Amazon and ordered it! So you mentioned you used this on your amps, but I know my issue is my preamp. What I’m going to do is either plug the McIntosh into the Hum-X and then plug the Hum-X into my Furman Elite, or plug the McIntosh into the Hum-X and then go to a different wall outlet thus separating the McIntosh from the circuit altogether. Someone suggested I try going direct to the wall outlet with the McIntosh. I figure trying that with the Hum-X might do it🤞🏻!

Thank you so much for this reply! Great to hear it solved your problem! Hopefully it’ll do the same for me. Otherwise St John the Evangelist down the street will be getting a call😂

On that note; I have been waiting for this to come up, I live in SoCal in the SDG&E jurisdiction just by the way. I have never had a  type AB Amp that didn't buzz and now I have a type D that is quiet as as a a night full of stars for no apparent difference in set up. I also had an old beach house that would cause my Krell 2250 to Buzz Loud when it was off when the Mr. Coffee came on in the kitchen. good Morning sunshine. THAT SYSTEM CONSISTENTLY BLEW DRIVERS AND EVENTUALLY FRIED THE POWER CONDITIONER DURING A T- STORM. Some of this hi-end equipment is touchier than the Manufactures would have us layman believe. peace out

Back in my radio days we designed a very nice control room. Then the engineer laid all the mic lines on top of the data lines. I was the only person who could hear the problem, therefore it didn't exist. 

I'd try a trial separation, or, if it's not a big deal, unhook everything, add back a line at a time. It's a great opportunity to dust & polish also.

Great replies @tkhill ​​​​@strawj! I used the opportunity when I relocated a few things when I introduced the McIntosh to clean and dust-another great call on this thread! You guys truly are awesome! And my Hum-X will arrive Thursday so tomorrow I try plugging the McIntosh into a separate outlet direct and see if that makes the buzz go away. Next step if that doesn’t work is to unplug everything 1 at a time from my Furman Elite. Then plug everything back one at a time to see if it in fact maybe isn’t the McIntosh. But I have already unplugged several components including the 2 subs and the cable box and that didn’t change anything. So I’ll go all the way in tomorrow.

I did disconnect all my XLR IC’s from the Titan amp and there was no buzz so I know it’s not the power amp. My IC’s are all Transparent Plus so I know they’re solid. I really am almost convinced it’s the McIntosh but we’ll dig a bit more tomorrow…

Thank you all once again for supporting and going on this journey with me👍🏻!
