you are right in one sense. in most cases, i am not comparing preamp a to preamp b in the same system.
my comments about a bunch of preamps auditioned in diefferent systems is that i find certain preamps lacking warmth--,i, a roll off in the range 1000 to 3000 hz, a slight peak in the range 90-200 hz and a laid back or recessed treble reponse, without regard to relative differences. if a preamp exhibits these characteristics in different systems, the chances are i won't report the sound of a stereo system as edgy or over detailed, especially if there is a tube amp, preamp and tube cd player in the system. i am using intuition nad the facts speak for themselves. i have auditioned some preamps in my own system and have compared several preamps in another system.
however, i would conjecture that i would not find any preamp designed today that is warm, based upon my definition.
