VAC Standard limited edition preamp

"Two different sounding machine, each one with different strenghts at a point I could'nt part with either one of them"

Andy, can you articulate some of those differences? I own cj gear; I'd like to try VAC but haven't had the opportunity.

I've realized nice gains by rolling the small tubes on my cj amps and preamps.

Thanks for the excellent descriptions Andr. I'm currently using Amperex in my 17LS. I really appreciated their lushness when I had a very dry cd player. Now I'd like something a little more articulate but I've heard that the Siemens are somewhat on the warm side - definitely not a bad thing unless, like in my case, your system is already leaning in that direction. Anyway, I'm hoping for a little of your luck in finding a great buy on a 16LS2.
