Someone in the JBL thread posted a link to some audiophile forum where one of the members was waxing poetic on the 530s as having the sweetest midrange and upper end he has heard for the money. These are the kind of guys buying $400 cables and interconnects and fancy smancy amps etc...
Whathifi reviewed them and indicated the same smooth, sweet mids and upper range. Nothing at all like other horn loaded compression drivers in the same price range. Compression drivers and horns done right can and do sound as good as any other methods.
Only one way to find out though and that is for the OP to try some in his room.
