Your level system is interesting. You SHOULD NEVER PLUG AN AMP INTO A POWER CONDITIONER despite whatever marking bs is saying!
if you want better sound just try plugging the power amp directly into the wall first!!!!
power conditioners are just for the front end!!!
pre amp DAC and stuff. Even if Audio quest says they have some special, super capacitor and blah blah blah. It’s all marketing.
yes, update all your cables because all your power cables that come from the company cost nothing therefore they are worth nothing because they were free with the thing.
