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

Well, I finally went to Vegas and heard the Sophia's with quality Marantz gear, and the Krell Resolution2's with Krell gear, both in quality listening rooms.
Here are my own impressions. Both are excellent.With amazingly clear detail and fast attack on the Sophia and they also sounded accurate but thin in the base to my ears - overall a bit dry. The Krells were very engaging but not as accurate. Summary - I know the rooms and equipment are different but my home system with the Polks sounds better in many ways with orchestral and rock, and the perhaps the Sophia's with simpler music. Overall I think that the Polks are more satisfying - just wish that I could shrink their size:) Given that I can not at this time justify speakers such as the Wilson Maxx 2, I will keep the Polks. So I will be going ahead with crossover upgrades, and ic and speaker wire and isolation products and see where I end up.

Check out the Harbeth line and also ProAc Response D series. Both make beautiful music with realistic body and tonality.
As you are satisfied enough with your speakers, there is no rush. Maybe you just feel out of touch with what has happened in the world of audio and are curious to get in once again. :) If so, that's what you should do, slowly. If you travel, see what that city has to offer. Network with other audiophiles in your area. Listen to ATC, Proac, Harbeth, Dynaudio if/when you can. There is alot of buzz here about a few small new companies: Green Mountain, Tyler, Silverline, Salk, Zu, etc. Some even let you try their speakerrs at home. So, I'll simply suggest to get exploring and keep us informed as to what you discover...
Thanks Aktchi, sage advice. I talked to Polk Audio today. They were very helpful. What he said was that if I was 95% satisfied with my Polks, then doing crossovers and new cables etc might bring me close to 100%, but if I was 70% satisfied, then another speaker might be a better place to put money. I'm probably 90% satisfied with the sound but do not like thier size and dated "big door" shape in my room.
So today been exploring Van Sneikert(sp)VR4SR and Gen III options etc. I will let you know how the search progresses.
