I have heard the 350 A/B'd with the 600 and the 350 holds it's own. I felt it had a little more punch to it for music than the 600 did, but for HT the extra depth and power of the 600 was noticeable and made for a better feel on impactful scenes. I have heard the EP500 recently, although it was not working right with a bad gain control but it seemed to me that the 500 has more of the same feel and impact the 600 does in a much smaller case.
