I have a Dish 721 receiver.  I notice some sound defects only on Sky Angel channels which sound like clicking or growling triggered by voice articulation.  I haven't noticed anyone else comment on this issue, so I thought I'd ask here.  Does anyone else notice it?  Is it a result of excessive compression?
