Help with speaker choice

I'm looking to replace my Totem Acoustic Hawks with something that offers heftier bass and more airy highs. The Hawk is an overall great performer with wonderful midrange and surprisingly deep bass for its small footprint, but I'm ready for a more powerful and more sophisticated replacement. I listen exclusively to records, mostly jazz and some rock, and use a solid state 2x50 watt amp, which will also be replaced at some point by a more powerful amp.

I'm looking for speakers that cost up to $5000. The 4 speakers I'm currently considering are:

1. Acoustic Zen Adagio
2. VMPS RM30
3. Vandersteen 3A
4. Silverline Sonatina III

I've only been able to listen to the Vandersteens and I do like the sound quite a lot. I think it's a great speaker for the money, but I've also heard great things about the other speakers. If anyone can offer advice or owns or heard the other performers, I'd really appreciate their feedback.
