Not my experience at all with V-caps. I love them, but who am I to argue with Mick.
I find the V-caps get rid of a lot of fuzz. Yes, they do seem increase detail, but I would rather describe them as more invisible. And don't forget, the upstream components have a lot to do with what one may hear from their Supratek.
As much as I respect Mick, he is one opinion. There are a lot of high-end manufacturers that have gone exclusively to V-caps.
So I guess to each his own, but I can't stand the fuzz of the Auricaps nor the haze of the Alps pots. I believe both components add a more diffuse sound to my Supratek and I don't like it. I prefer cystal clear detail that is still musical. And I don't think those two things are mutually exclusive. If the V-caps were brittle or harsh in my system I would take them out in a heartbeat (since I was the one who put them in). I just haven't found V-caps to be a negative in any way in my system. But I do have a Forsell Air Reference Transport (noted for it's analog sound) and an Audio Note DAC in front of my Supratek.
Clearly, the system as a whole has to be viewed in the context of what one component may do to the sound. If your system is smooth, I believe V-caps will give you more smooth, if there is any harshness anywhere in your system, I believe V-caps will help expose that. YMMV
