I am running a Sony 2ES receiver with a Sony 685V DVD/CD/SACD player. I am wondering if I should buy a 999ES before they become unavailable since I believe they are no longer manufacturing them. I realize that I most likely won't see or hear a major improvement, but as it turns out I'm pretty happy with my ES receiver and would like a matching ES DVD player. I just don't know if its worth the ~$750.00 or not. Any thoughts?
