Why an active preamp with Rock-N-Roll ?

Have yet to hear, in my 20+ years of experience around high end audio stores and 1000'S OF SYSTEMS, one single passive/pre set up system that sounded as dynamic potentially as a good active preamped system! Something is to be said about the gain stage from an active preamp, and maybe has to do with impedance matching quit a lot as well. Without trying to get technical, it just is the way it is.

I think that's a lot of nice theories that Sogood is putting forth. But bottom line is that I'll take his passive preamp out of his system, and replace it with a good active, play some rock, and we'll see which is more dynamic! Infact, I'll put money on it that EVERY LISTENER in the room will tell you which is more dynamic!..that's right, the active one...tube, solid state, or otherwise!
And, for the record, I never said active is better than passive. I said for dynamics, active is supperior. If someone likes lots of instrumental, vocals, light jazz and classical, then I used to use a passive to superb effect myself! I'm not saying that at all. But, for dynamic ability, you're better off with active pre's in my experience.
Now maybe "Sogood" has some very dynamic high efficiency speakers, and a passive isn't hurting his dynamics as much as it may other set up's. But the active still has advantages here, all things considered.
