Battery-Powered Audio System Buzzing?

@sid-hoff-frenchman I'm not sure if I'm tracking. Are you testing or horsing around with the battery? Or will you be integrating with your system for mid-term or long-term use? If it's a mid- or long-term route, I would advise against taking that road. No matter what benefit or perceived benefit  you are getting from using it, forgo it. There may be unknown or unseen risks that could emerge later, potentially damaging your audio gear. I'm sure the designers of battery manufacturers do not have home audio gear in mind.  Based on my experiences and observations, even the most well-planned designs and tested products can still fail at some point. Nuclear power plants, aircraft, vehicles, motors, and batteries are good examples.

Forgot to add Tesla

@immatthewj After A/B-ing with the upstairs system (Schiit Tyrs/Tekton Encores) I've come to the conclusion that while there is a difference between battery and wall power, it is very slight. One is not better than the other. Not worth the annoyance of dealing with the batteries. I will A/B more extensively with the downstairs system (Schiit Aegir/Tekton Impacts) and report back. It was on that system that I originally noticed the big difference I described above. We'll see if that holds under more scrutiny.

@goldenways I definitely don't want to harm my equipment. I'll reach out to the manufacturers of all my gear and see what they think about powering their stuff with batteries.

Sounds like a good plan. My guess is the manufactures are not going to stake their reputation on batteries. They will stick with the tried and true way that is normally done. Even if they say go for it, most likely there will be a large asterisk to the statement. My asterisk to my opinion “I might be wrong”
