Not sure if the OP is a member (or how long you need to be to post), but the largely subjectivist Pink Fish Media classified section may be worth a look. It's a huge forum and has all sorts looking in, objectivists too, to be fair. HiFi Wigwam may be of interest as well, as well as the Art of Sound forum.
Not sure if any of the above would tolerate a newbie joining just to sell something though, but I mention them just in case.
