Summary: It certainly beats all cheaper players. You could spring for the Oppo BDP-105 (Est. $1,200) , the top-of-the-line universal disc player, and get even better sound and play more types of discs (including Blu-ray, SACD and more). But for pure sound quality at $550, nothing beats the Marantz CD6005.
Pros: Outstanding sound quality, USB jack lets you play music while charging your iPod/iPhone/iPad, Plenty of random and repeat play options, Great built-in headphone amp, Slim design
