25 year old polk 2.3's will I hear an improvement?

I am considering upgrading my 25 year old Polk 2.3 SDA speakers to something such as Wilson Sophia, Krell Resolution 2 or Usher Dancers. I have already upgraded the tweeters in the Polks and was very pleased with the difference. Over the years I have upgraded amp to Aragon 8008BB and source to NorthStar trans and DAC and also noticed improvement.
I live in a rural area and am willing to travel 8 hours round trip to hear new speakers but very little chance I can hear them at home before purchase.
Please, oh wise one's anyone make a similar upgrade and were happy or not with thier purchase? If happy, what type of improvement might I expect? Thanks

a minty used set of hales(heavy, but not as big as the polks) and a fraction of the cost of speakers that are nowhere close to being its equal.

Chadnliz - thanks for your comment. I looked at Legacy - gorgeous but at 55" too tall for me in front of window placement. I am looking for 45 inches or under. Talked to VAN's son. He states that he has his Van jrs at 12" from back wall and they do fine. And that the newer Vans are designed with close to front wall pacemnet in mind. Do you have experience that contradicts this?
Jaybo. Thanks - I will look at the Hales.

All speakers radiate bass in all directions..so you will get some reflections and cancellations from the rear wall....the only way to eliminate this is with acoustic treatments,with soffit mounting or placement very far from the wall. (as someone mentioned, ports can often make it worse and I agree, as tuned ports have a strong resonance/nonlinear response)....see this link for details

I am surprised Van jr did not mention this...as it is well known.

All I can say is with the JR's they were far from the back wall and the ambience was comming off the wall...I can only assume that close wall may be a problem.

Thanks for the cogent responses. It looks like I may get to audition a pair of jrs this week and if possible will play with to the wall distance and see what happens.
