Where/what is the best place to sell used components

Where would one find a "budding audiophile"?

Lots of people are moving things on Facebook Marketplace, on a group called Audiophile Swap and Shop.it’s a private group with almost 57K members. People selling lower end to higher end. I have had good luck and know others that have as well.

Unless you sell everything face to face, I’m not sure the hassles of shipping, etc are worth it. Personally, I would donate them and write off the donation. It will be worth more overall.

Similar to what has been suggested - do you perhaps have nephews or nieces who may appreciate a special gift?   It could be life changing, so you will have to think very carefully....

Selling low-dollar stuff is a pain.  Good packing materials and shipping are very expensive, not to mention the commissions on the auction sites. Then, people get it and they have buyers' remorse and want to return it, as if they bought from a store. It's not worth it, IMO.  I remember selling my father's old ESL tonearm that I described as a "rusty piece of junk" in my ad, but I was selling because it was rare and someone might want it to restore.  Don't think the buyer didn't complain because the plastic base was cracked or whatever.  Nowdays, I pretty much sell in person or keep it.
