best towers for $3000 ?

I have been running Paradigm Studio-20s in my 2ch living room system, music only ... jazz, classical, some rock. Bass could be better defined and I have upgradeitis! Looking for towers this time and something attractive .... WAF is important if I want to upgrade. Looking for some thoughts here. There are so many good speakers out there and I want to target some models for auditioning somehow. I could also go used.
Some possible candidates ...
* PSB synchrony 2s
* Salk Songtowers
* Vienna
* Joseph Audio
* Thiel CS1.6 or 2.4
* ProAc ?

Others I miossed?

Thx
