Is the upgrade from Scout 1.1 to the Prime worth it?


I know this is totally subjective. I am looking to hear experiences from anyone who has made the change as well as opinions on weather it would be a worthwhile/noticeable upgrade given my current setup.  Would the investment be spent better elsewhere?

Current system:
Primaluna ProLogue two (stock tubes)
Icon Audio ps1 MKII (MM only) reissue gold lion ECC83 tubes
VPI Scout 1.1 stock except for the counter intuitive 
Ortofon 2M Bronze
VPI 16.5 record cleaning machine 
128x128wilson667
Does  it sound better.  I guess.  Is it 4000.00 better, not sure.  buy more records.
So I thought I would post a follow up. I did end up with the Prime. I will say what I noticed right away was how quiet it was.  Absolutely no hint of noise. Not that I can say that I ever noticed any noise with my scout but the Prime was noticeably quieter. The sound over all is clearer and the bass is more extended and tight. I also upgraded to the 2m black from the bronze. The bronze was definitely less picky about setup. The black over has the same basic sound just has a little more . I would say the black is an improvement but the bronze is s not far behind.
