I just recently replaced my Sony 995 with a Marantz 7500, and the differences are astonishing. Most of the Sonys will sound overly processed and a bit more artificial than a good low to mid range unit from HK or Onkyo. Without changing anything but the receiver in my system the imaging improved significantly, especially outside the sweet spot. So, skip the Sony and get a better quality AVR, it may not have the features and may seem like your getting less, but trust us, your getting alot more of what counts.
