I recently purchased another Rachael amp for a second system.  The new amp has V-caps, the original is stock.  The new amp was built in June and the original owner says it does not have many hours on it.

I put them side by side and did some A/B testing.  Same powercord, interconnects, etc.  First with my current set of Rachael tubes, then I started varying things.

I was somewhat surprised at how much better the non-broken in V-cap Rachael sounded and that the best tube set for it was the stock tube set. To me, V-caps sounded a little darker and I consider the stock tube set to be a brighter set of tubes.  The combination yielded some good synergy.  

Overall, the V-cap amp was much more engaging.  You could hear more of the musician's emotion coming through.

Anyway, I often wondered if the V-caps upgrade was worth it and now I can say, even with a fairly new amp, yes.  It will be interesting to see how it goes as the amp seasons.

I think I am just going to load up the van with everything, grab about two days worth of food & beverage and head your way
