In my view and as near as I can tell, the Axiom looks fairly interesting. This one is new to me and I'm not sure exactly how he gets the Alps pot out of the signal path, but, if that approach is sound, then I believe I might be considering that thing myself, were I in your situ...just could be the way to go, here. Maybe somebody has tried it. Not as sure about the Bottlehead, it could be ok too, but I dunno.
Update: Oh, ok, I see now where I misread the website text. The pot simply shunts the signal to ground. That may work, but the pot would likely still exert some influence on the sound quality...hence the stepped version for $500. In that sense it may not be the best value...unless somebody has tried it out.
