My hubby had a power amplifier for his stereo before I got here to the US but it doesn’t work well anymore. I really like to listen to music but him not so much anymore. The amplifier works part of the time but then it starts cutting out and makes a weird screeching noise when it is left on for a while. I would like to buy a new amplifier but it is not high on our priority list. Maybe one of these days I can talk my hubby into getting me a new one, like for Christmas maybe?
