Hi all

I'm about to buy Glenn's latest preamp offering, the "25RS LS" which is a souped-up linestage version of the RS two box solution. The LS comes in two varieties, which as the title suggests can incorporate either a 12BH7 or an old school 6SL7 in the linestage slots (x 2).

I have a 25RS at the moment which has a single BH7 which works well for my tastes in that it's fairly lean sounding. Reading up though I haven't found a single post that doesn't extol the virtues of the 6SL7 that can be found in some of Glenn's earlier preamps. So I am a bit stuck which way to go, any opinions or thoughts based on experience would be useful.
