exSG Posted July 28, 2021 Posted July 28, 2021 Hi All, My speakers are emitting rather audible static noise, one louder than the other. I tried isolating the source and it seems it is caused by the McIntosh C2500 preamp. Is this possible? I have a Xindak power conditioner connected to wall and from the conditioner to digital sources and the preamp. The power amps are connected directly to the wall. It could not be the wireless router or Node 2i as the noise is still there when I switched to cdp. What can I do? Thanks.
GregWormald Posted July 29, 2021 Posted July 29, 2021 First off, disconnect everything from the pre-amp, clean all connectors and then re-connect.
exSG Posted July 29, 2021 Author Posted July 29, 2021 Thanks for your replies. I disconnected the xlr to mono blocks and it was quiet. Re-connected the xlr cables and disconnected the source cdp and node, and the static noise is still there. So it must be the C2500. The tubes have never been changed. The right speaker is quiet though. Who would you recommend to have this checked and how much would it cost roughly?

Hi Greg, Thank you for your advice. I should have tried that first. I sent it in for a check and there was no fault. Then, I bought a can of Dexoit and cleaned all the connectors and the static noise went away. After twenty years of being an audiophile, I am still learning. Cheers. 2
