Having owned my B-stock 990 for a couple of months now, I've always had it connected to one of those powered Terk antennas for the tuner. Didn't have great reception nor did my Parasound HT processor that the 990 replaced. So today I decided to use the included antennas that came with the 990 and would you know, every station came in much clearer! It is as if a couple of layers of grunge were removed. Imaging and detail were greatly improved as well as the depth of the sound stage. Every station has a much lower background noise now. Luckily, I have a wall unit that is housing everything so the AM/FM antennas are well hidden. It is nice not to have the wall wart from the Terk being used. Now I can really enjoy listening to the 990's tuner.
