I know we all post about what we have used. My tube background isn't that extensive but I've had the Rogers 65v-2, I still own the LTA Z40+ integrated and now I also own the Don Sachs Valhalla. The Valhalla is about 33 watts and is really really nice. This is made now by someone Don taught to make it and has a decent warranty. If it interests you at all, I can link up the site that describes it and put you in touch with the guy who makes them now.
