All active circuits have more distortion/s and colourations than a good passive device. (re: Nelsons Pass's article in my first post and he sells active pre's))
One way you can figure this out, is if you have a source that is a good low output impedance, say below 1kohm which most are, and feed it direct into your poweramp, which should be the industry standard of 33kohm or higher which most are. This will be the most transparent/dynamic/uncoloured sound you can get.
Put on a known quiet starting CD (with your finger on the stop button just in case) and listen. This is the most transparent/dynamic way of getting the source signal to the poweramp, and I'll bet my last dollar that the well implemented passive volume control comes the closest to this sound or equals it.
The only way an active preamp can sound more dynamic than this is two ways. It is distorting with TIM giving you the impression of more leading edge dynamics or it has a built in dynamic rage enhancer (DBX) which sound like rubbish.
