Although the AR dealer here in Holland adviced to stick with the original Sovtek 6922 for my LS-2 pre I decided to play around with it, helped by a friend who graciously lend me two Philips tubes, a Gold Aero and a Sylvania. All sound different, so it's a matter of taste. I prefer a JJ I bought. It just shows you can 'tune' the AR to suit your taste and system.
