I have a older audio receiver that works fine (other than the lousy user interface) with only analog inputs. I haven't bothered to upgrade since it would be one more piece of equipment I would have to sell since I have no other use for it. Since I wouldn't get squat for it I have kepted it. Comming from a HD TV, HD DVR, CD player, DVD player using an analog path to the receiver and comparing that to getting a new receiver with digital inputs is there really a difference regarding: 1. The basic 'audio' (sonic) quality: tonal range, dynamic range, imaging etc. 2. Separation and surround sound effects (I'm not using a subwoofer or center channel speakers). I know how hyped "digital" everything is these days and I question if it is really better especially considering all the compression & processing of most sources??
