Picked up a d3020 a few days ago, and like most have heard, it sounds great and the variety of input options are wonderful. I have two questions. When I plug in my sub, the high pass filter to the main speakers does not turn on. Ive spoken to tech support and was told to re-flash the firmware, but that didn't fix it. I was wondering if anyone has noticed this when using the sub out, or alternatively is the high pass filter working correctly for you. Secondly I notice the amp is hot always, not just very warm...noticeably hot. Even if at low volume in the background. I don't know if this is bad or normal, but just feels too hot.
