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
A 2M Bronze, yeah a Prime can do much better. A Cadenza Bronze however, would be a sweet match. 
The OP listed a MM only phono stage.  Kinda hard to drive a low output MC.  I agree that the Prime could use a better cart, but an Ortofon Black might be a better option.

I just setup one of the new MOFI UltraTrackers ($499) and am pretty impressed with it so far.  The MasterTracker is even better.
The Prime is a much better turntable but actually to improve
the sound resolution much more would require a MC cartridge.
I think that you would find that even on your Scout changing to
a MC pre amp or using a step up transformer such as one
from Bob's devices paired with a good MC cartridge would make a huge difference. 
I also went from a Scout 1.1 to a Prime. As good as the Scout is, there's no comparison. Agree with the posters recommending a cartridge upgrade. I went from a Ortofon 2M Black to an Ortofon Cadenza Bronze plus Bob's VPI SUT. The sonics are outstanding.
Thank you I really appreciate all of your opinions. I think I will make the leap to the Prime. I will also likely upgrade the Bronze to the Black until I can afford to do a nice MC and step up at the same time.  I will be back for recommendations.
