Bass leaves after amp warms up?

Fishing, I'm pretty sure I suggesting removing the power conditioner on page one.

The problem with most power conditioners, whether passive or active, is they force you to use a common power cord. If you get a voltage drop over that cord, it will rob the amplifiers of full output power. This is audible and measurable. If your amps draw more power after warmed up, there could be a tipping point. Maybe that takes about 1/2 hour?

Our amplifiers are quite unhappy with most power conditioners, especially the regenerator kind.

If the lack of a power conditioner continues to fix the problem, ditch the conditioner, or just use it on your source components.
