When using Spotify Connect to play music on my new Acton Multi-Room speaker I get intermittent audio crackling, almost like static. Is anyone else having this problem? It does not happen with other audio sources, like internet radio stations.
I'm using a Origin 50 combo. I find when I crank the master volume and play at higher volumes, I get what sounds like glassy tube rattle. There is also just generally more noise than I would expect. I tried it with a different cabinet. It seems to be worst when using the internal speaker or when the amp is sitting on top of the external cabinet... my assumption is that the physical vibrations due to high volume are causing the tubes to rattle. The rattling is getting passed through the speaker, meaning that it is not just simply a physical rattle, but it is a transferred into the signal.
It sounds similar to some of the problems on the internet with the Class 5 that had rattling. Someone suggested that tube rings would fix it. Any suggestions?
