I've owned the VK5, VK5i, VK30, and VK30SE. The original VK5 doesn't give up much, if anything at all to the VK5i, or any of the BAT preamps. Recently observed a used VK5 for sale @ $975. If this is the reason your interest in one has peaked, I'd grab it quick before it's gone...that's a give away if I ever saw one.
Enjoy!
