First of all the very best wishes for the New Year!
I received my Philips tubes today and have only used them for about two hours now. My Torpedo has the snubber-caps upgrade, as well as the Hammond choke, and use it for my AKG k702's. Compared to the other tubes I've used sofar (6J6, 6J6W and 5964), I agree with TomB's observations that the Philips tubes provide more bass than the other tubes. Bass is far richer, yet remians detailed and fluent. It never gets "boomy" (if that's a word
). Just what my k702's needed! Also, there's even more detail in the mids than before. I would recommend going for any of these newly discovered tubes!
