Cable Company is an Ayon dealer. They may have a demo unit to send you so you can try it first.
As far as what CD player is the best from your list above, I can't say. It will come down to personal preference more than anything. I really like Ayre products so I would probably take the CX-7 for myself. Also, Ayre is built extremely well, so if this is your last player, that's something to consider. No only that, Ayre upgrades their products on a regular basis. No need to keep trading it in for new models.
