Cheap amp broke, looking for a replacement

I had a cheap Bluetooth capable stereo amp in my kitchen paired with some wharfedale book shelf speakers up on top of the cupboards for when I like to boogie down making food. It's just lost one channel and I'm 99% sure it's cooked from age, quality and hard use. I'll be donating it in case someone can fix it but meanwhile I could do with a compact replacement.

I can see a large number of offerings on places like Amazon but no idea what is any good and what's just a paperweight.

Any advice guys?
