I have various speakers and audio equipment for sale. They 7-10 years old. Should I list?

I have a variety of audio and speakers available for sale. Included are B&W 600 series bookshelf speakers, Paradigm CC series speakers, Kef, Denon receiver, Rotel preamp, and Def Tech sub. There are more. Most have original packaging. I'm cleaning out my music room looking to raise some funds to offset upgrades. Can give a spreadsheet and what I want for sale but really want to see if anyone is really interested. These units are 7-10 years old
