In my experience, trying to resell lesser known gear can be very hit or miss. Unless the gear is red hot, flavor of the month based on multiple rave reviews and lots of forum chatter. Think maybe early Denafrips before people knew the name. Anything less than that, even if it really excellent, and even if it was already a very good deal at the original price, is tough to find a buyer. I have let things sit for almost a year before I got any interest and at that point I was ready to just keep the stuff.
I've learned that selling to local friends or acquaintences is much better, if you can find some sort of network that way. It's tough though.
