Lamp wire is also fine, often times they are the same / interchangeable.
An amp? Well there’s a whole lot of options there from multi channel home theater units down to just a stereo mini amp.
If you just want to power some old speakers I’d lean towards a stereo mini amp on Amazon. Then maybe a cheap bluetooth receiver so you can easily pair your phone for some modern streaming support.




I agree with you but also about 90% of watching on my instance happens on smart TV’s. So even though I would like to have oidc supported for the occasional phone/pc user I would still need something basic that a TV can use.
