speaker makes pop when amp is turned off with power strip

[olds1959special]

Is there a way to fix this (or a better option for a mini amp with treble/bass control that will allow me to turn off with the power strip?) I'm using the original Fosi BT20A.

That costs more than the amplifier:

Yes, I'm aware.

Didn't see cost mentioned as a parameter in the OP.

I’m not buying this. It’s too expensive. I can get a new and better amp for less than that. Is there an amp that doesn’t have this behavior?

It’s not the end of the world but I have to adhere to a specific startup and shutdown procedure to avoid the popping. (turning the BT20A off at the amp before anything else, and turning it on after turning on everything else at startup.)

I really liked using one switch for all my speakers before I got the BT20A. Oh well.

I would question why a 'pop' is a problem? Yes, it's nicer if there's no switch-on or switch-off pop, but if it's a 'pop' rather than a 'THUMP' why it matters?
My amps have a quiet pop on switch-on (silent on switch-off) which I've taken to mean, "Hello, Let us entertain you"

I would get concerned with a massive THUMP, as that can damage stuff and frighten the horses, but a pop?

This is not a serious problem, so don't stay awake trying to fix it. I take it that you're trying to avoid 'vampire power leakage', hence the power strip. Don't worry about yr power bill going up a nickel, unplug the unit from the strip and plug it into the wall. And I would leave it on all the time, like I do with my Topping PA3s.

Does it pop with no input cables connected to it?

I changed the amp to Aiyima A70 Mono and the pop is really small now, and I think only happens when powering on.
