I would guess the poster of X5 that a preowned set was being helpful. Some cannot afford a new set so this is always an option when available. That is why Audiogon and others exist, and there must be many buyers or they would not be in business and even then buyers for the most part still try to low ball you even when the price is more than fair. I guess everyone wants to get things on the cheap as possible and some I noticed buy and resell at a higher price than they purchased the item for, that I find unethical.
And to be honest Audiophiles are always trying to find something better than want they have, and that is a state of mind because good is good, then you doing change for change sake, their is no absolute sound, but there is the right sound to our own taste and that is the absolute sound. Then of course if we want to upgrade our Spatial Audio speakers we would have to resell them right? and hope for someone to buy them so you can buy a new speaker so I would hope to 1st place to let folks know would be a site where so many visit to talk about Spatial speakers, Clayton then gets a new order from us once we sell what we have. It is a win.win.
