upgrades to Spectron Musician III Mk 2

I took the plunge and bought a Musician III Mk 2 with no additional upgrades used here on Agon last week. I should have it in my possession in the nest few days.

While I plan on listening to it for awhile in its present form, I wanted to ask you fellow Spectron owners what your thoughts were with regard to the V-cap and Bybee filter upgrades. I've read the info on Spectron's website re/each but want some owner's opinions, especially since I probably won't have the bucks to do both upgrades at the same time right now. Thanks.
