i own Leben CS600 integerated amp,which can accomodate 350B,KT66-77-88 and 6L6Gc,which tube sounds best to provide delicate ,resolving and relaxed sound
KT66 IMO. The 6L6GC is also relaxed but isn't as resolving as the KT66. I currently use Groove Tubes KT66C with a hardness rating of 10 in my McIntosh MC240, and I find them to be excellent.
