Can anyone tell me once and for all the compatability between the av2000 and the sony 50es? Is anyone using this combination currently? I have the 50ES and have played with the 2000 on loaner. It seemed like I could get it to do everything BUT the DSP settings and obviously the 2way stuff. But it sounds like there may be other issues. I really like it, and would love to get it but I want to make sure I'm not missing anything else.
