Advertisements I replaced an aging Premiere with an Edge cable model a couple days ago. Setup was unexpectedly easy, especially considering that I used the CableCard that had been in the Premiere since I first set it up. I used Comcast's activation website and was very happy that it worked on the first attempt. The new unit is much snappier and having the extra tuners and storage is great. My one concern is that the Edge seems noticeably noisier than the Premiere. With ambient noise in the living room, I can hear the Edge buzzing from about 7-8 feet away. It sounds more like it's the fan and not the HD making the buzzing noise. Are all Edge units like this? Is it worth exchanging?
