I've had a similar experience lately. I have two pairs of speakers up for three weeks now, that are both fantastic and coveted speakers in their own right. Both at fair prices. My past experience has dictated that nothing I've sold has taken more than a couple of weeks to sell, with many selling within a few days and some in a few minutes. Speakers always seem to take a bit more patience, but three weeks is unexpected. I've had nothing more than tire-kickers and one (non-member) buyer who backed out after committing to buy. I think the market is a bit off these days myself. A good friend of mine had a similar experience with a preamp just recently - It took a month to sell, in spite of being a coveted component at a good price.
