RE: Actually...

I know many have state they prefer active for things like "dynamics", and impedance matching is a factor, but transformer based passive solutions take care of that very well.

Here is an interesting quote from Art Dudley's AX-5 integrated amp review:

"As Hansen explains, most active preamplifiers work by applying to the input signal a certain amount of voltage gain, so the signal can effectively drive a power amplifier. But in order for there to be a reasonable volume range—and to simply keep the playback level from being too loud—the voltage-gain stage is preceded by a potentiometer, which attenuates the signal. The drawback of this is that such a preamp will exhibit its maximal signal/noise ratio only at its maximal (unattenuated) volume. As Hansen puts it, "Since most preamps are used anywhere between –10dB and –40dB for an average listening level, this means the S/N ratio in actual use will be 10–40dB worse than on the spec sheet."
