I suppose that's one way to get people to read your thread.

At this point in the game, I think getting the right speaker for your ears and budget should be be your top priority. No matter how much better a different receiver can possibly be than the one you now have, changing speakers will make a bigger difference.

You mentioned that the Monitor 3s sounded too laid back AND sibilant. While I can't guarantee that the M22s will not sound sibilant in your room -- they are very flat and accurate speakers and will reflect the quality of recordings quite well -- I have a pair of M22s and I absolutely love them. In my room, they have no hint of sibilance.
