I second Atmasphere's comments.
V-cap upgrades in my MP-3 pre and M-60 amps have improved the sound far more than any tube rolling (and I've tried many different tubes).
That said, even V-caps do not alter system sound nearly as much as a synergistic component (i.e.source/pre/amp/loudspeaker) change, but that's stating the obvious - I hope!
