Morricab hits it right with his comments in my experience.
I have been using two preamps on and off for the last decade or so. A DIY SET single stage VT137 triode preamp with stepped DACT volume pot and a Sonic Euphoria autoformer volume control (SE).
In terms of tonal balance, they are virtually identical. I think the SE is slightly more focused sounding, VERY slightly less noisy (my VT137 preamp is VERY quiet four an active, tube preamp, a requirment since I use 100db+ effiecient horns) and I never have to turn it off or on.
My active VT137 preamp sounds bigger (wider, deeper soundstage), has more "air" or a sense of room accoustics where the recording occurred, actually sounds more transparent (that always get me, how can an active preamp sound more transparent than an autoformer Which is basically a long wire?) and has better bass (deeper, bigger, more). I like both sounds.
I have experiemented with many resistive based passives and agree that they are more transparent than my SE and probably a bit more than my VT137 pre but they always sound dryish, strangly lifeless and ultimately somewhat boring. I can run my PS PWD II dac straight into my amps without a preamp and I get that same sound as with a resistive passive preamp (the sound is detailed, transparent, fast) but ultimately somewhat fatiguing and lifeless.
