I see the only thing you have listed in Marketplace is a twenty-year-old, 1/2 meter pair of Cardas Golden Cross interconnect, asking $400.00. To me, it sounds like a lot, particularly its age and short length.
" I think that if (when) I offer more of my unneeded stuff, I shall know how to manage ridiculous offers. How would a car salesman respond if I offered $20k on an $80k car?"
Am I assuming a used car? Some new cars lose twenty percent when you drive them off the lot. And a used car? The variables of what a used car would sell for are infinite. Seems like you have little experience selling anything, but you will figure it out. My experience has been: You never know what will sell and what sits months without a bite. I once got an older Marantz amplifier given to me, and it had an issue. I found out that an internal fuse on one channel would go up in flames(like a torch) when turned on. I didn’t want to deal with it, so I put it up on CL, best offer. I even had a short video of the flameout. After putting the ad up, I was heading out maybe a half hour later, and for some reason, I checked the ad before I left. I had a half dozen responses, some begging me to call them back quickly. Apparently, what I thought didn’t have much value had quite a bit of value, but back then, I didn’t know much about what was what in audio.
