Good starter amp recommendation

Was lurking for a while, decided to post.

I have an old system with Energy RC-30 speakers and currently using a Denon x3400h to drive them. The system is used mostly 80/20 for music/movies, and uses an Energy RC-LCR center for movies.

Would like to add a simple 2/3 channel amp for around $1000 to improve the sound and was looking at some more recommendations. Want it to be a good part of the system, but since the speakers are pretty basic, don't look for anything too fancy, but good enough to upgrade the speakers later on.

Looking around the forum, the following is my short list:
van Alstine SET 120 or Synergy 240/3
Odyssey Khartago (or used Stratos)
Anthem PVA or MCA (used is all I can afford, probably)
Parasound A23

Would like to hear any suggestions.
