I find all this cap discourse quite fascinating. Some say V-caps are the greatest thing. some say the opposite. I think it may come down to component matching and personal preference.
One case that highlights this is Srajan Ebaen's Supratek Cabernet Dual preamp. He had the caps changed to V-caps just to have them resersed back to the old caps a few months later. At the other end, there are some Supratek users that simply swear by the V-caps.
I'll certainly check with Simon when I go for the MK II upgrade.
