Sean - what I do in my own reference system to eliminate most of the "dynamic loading effects" is the following:
Preamp with very low-impedance output - 7 ohms
Power amps with very low impedance output
Speakers with flat impedance response - 3 ohms
Cables with extremely low loss and dielectric absorption
This way, I have a reference system that is extremely tolerant to differing loads. The interaction between components is small. This way when I mod different components, I can insert them into the system and really hear the improvement and not spend all of my time troubleshooting and swapping other components to get a good synergy. I want to eliminate as many variables as possible.
I do have one known issue. The power amps need significant current to stay dynamic. A passive linestage proved to be dissapointing to me.
At HE2003, I used all tubed components in our active system. Here, synergy between speakers and amps was very significant. Once we found this synergy, the magic happened. However, as always, using our cables avoided having the cables "add" any sonic signature of their own. And we used 15-foot unshielded IC's too.
