Think first about running dedicated power lines direct from your electrical panel ALONG with audiophile grade wall receptacles as a best-step-up in audio performance.Add in a panel whole house SIEMENS surge protector at the panel. That’s a separate line for the amp and a second line for your source. It will be far better approach than a Pwr Cond simple plug in .
Then, ensure your components power cords linked to the anudiophile grade wall outlets are up to the task.
Ok….sure ….a quality build high-end power conditioner can maybe provide a further smaller further incremental step up, particularly if you have wild power swings experiences in some older buildings.
ok …if dedicated lines are a no-go, then a quality build Pwr Cond might help a bit.
But as pointed out in other posts, it’s a summary of the entire cradle-to-grave power supplied to your components that determines your audio performance quotient….not any Pwr Cond, in isolation.
