Purging/passing along your collection of audio gear
Here in the Colonies/North America/USA there is the Craigslist for locals, the Reverb/eBay (but the shipping of gear for Reverb & eBay is painful), the local ham radio swap meets/ham fests (shout out to https://www.electronicsfleamarket.com/ (AKA eFlea or EFM friends), but I have not had much success. Yes, I have been able to pass some nice speakers off to new homes but there is other gear that needs to move on.
I buy most of my gear using https://www.usaudiomart.com/ and https://www.audiogon.com/.
Large speakers and amps over 100lbs are always tricky. Anything worth a fair amount should be shipped freight and palletized.
My mom gave away some of her gigging gear through local music schools. Now she's getting a living-room concert by the Celtic band that is giving it a second life :-)
