There would be a very noticeable improvement.
In my exp clarity, nuance, macro & micro dynamics, the imaging and spread of the orchestra, the definition of the individual instruments and the "thrill" of the performance will all be nicely enhanced.
I liken the effect to the benefits of being able to finely adjust high quailty binoculars for each eye or better yet the process one goes through in determining the strength and characteristics of lens for a new set of glasses-with every step up the MIT pc line sharpening the "vision" of the music that much more.
That said,whether you move up simply relates to your level of satisfaction-and budget.
I like the fact that I feel investing in high quality pc's, particularly MIT's Oracle level, is very worthwhile for the long term. AC power is a very well known & stable commodity so the improvements provided will not be 'obsoleted' by changing power technology in our(my) lifetime. I have the experience of having found the benefits of AC conditiong back in the early 90's with MIT's original Z Stabilizer (with top quality Levinson & Krell amps); and have added other MIT conditionersand enhanced pc's as they came along(and I could afford them) so I am well aware of the fact that power improvement products can have a very synergistic "additive" effect with complementary placement in the system. I believe digital, in one form or another, will be our source for music. In my experience high quality digital playback devices(even the very high level Levinson CDP of my Dentist friend) benefit greatly from ultra pure power- and also generate noise- and these pc's address both factors.
Too long a reply perhaps-but we are just enjoying and sharing. Happy listening. Pete
