Tvad, yes, (I guess I was thinking of the TAD-150 Signature preamp). The upgrade with the Auricaps and the filter caps is the model I was referring to. I don't think there is a TAD-60 "Signature," just this upgraded version. And I would definitely recommend going for the upgrade as I'm getting pretty impressive, tight, and controlled bass out of this unit.
Another thing to ask for (even if it costs a little extra) is Paul's heavy-duty gray power cord. It made a nice improvement in sound over some much more expensive cords I tried.
