I don't have a specific recommendation, but if you can solder, you can build a set for $30 that'll out perform anything you can get off the rack for that money.If you're really serious about performance, forget the IC. Arrange your CDP and amp back to back, open up the covers, and solder the CDP output directly to the amp's input, bypassing the RCA jacks altogether. I'm only half joking of course, but the best IC is no IC.
