At just about you price range in the used market would be a Resolution Audio Opus 21 with GNSC mods (probably have to stretch your budget by about $300-400). This is an excellent player and should be considered certainly above several of these other players and in-line with some. I would put this more in line with the better Ayre players. Since I have not personally listened to the Raysonic, I better not comment on that unit, having heard good things about it (mostly by dealers on this site).
