A good idea is a dedicated plug in the wall directly connected to the central main electrical grid panel.. The difference in the electrical noise floor of the system equal a big upgrade in some case in signals clarity...In my case it was... When i loose my dedicated room i never suspected that my secondary electrical panel at the second floor where was my dedicated room could be so noisy... I even used a panamax filtering purifier...
I only use one plug in the wall for my system now with no more Panamax because too noisy even treated with my homemade recipe 😊 ...I am on headphone and i used a low noise floor battery dac too ...I use the dac as a files bank no more link with a noisy computer .... It was a designed dap that work fixed on a desk now, i never listen music outdoors in a sleepwalking way ...😁
Best idea i ever had compared to other dacs... The last one was a NOS dac with an internal battery, but it was connected permanently to a very good charger for his external battery and was then more noisy in spite of the charger non linear alleged noisy-less quality ...
The electrical noise floor level is the most unsuspected enemy of your audio...With vibrations and no acoustic control of the room...
