Hi bryan,
SoundOfMind gave you sound advice regarding this at the AVS Forums. And he said it well.
To add to that, based on my experience, getting the 4311 will max out the capabilities of your entry level speakers to the point that you may begin to notice its limitations and start looking for better speakers (but you will still notice an improvement over the entry level 1911). So in a sense, you are not maximizing the potential of the 4311 since it can improve SQ even more with much better speakers. That's what happened in my case, after the AVR upgrades and the transfer to a dedicated room with acoustic treatment, it became obvious that the weaker link was my speakers.
It might be better to invest in better speakers right now as well as mid-level receivers such as the 2312, 3312, or Onkyo 709-809, for a more overall balanced SQ improvement. Or go all out on speakers which you will keep for more years than the AVR, which comes out with new models every year--then ipon mode for the AVR, until the right time comes to get one. Baka by that time XT32 will trickle down to the mid-level AVRs at a cheaper price.
