    Relevant data that addresses the two specific points: That cable dielectric (if quality made) undergoes no break in characteristics and that passive devices have greater non-linearity than active devices (which necessarily must also have some passive devices in order to function).

    Show me a study that actually tests the very highest quality stuff (teflon) as a dielectric that has proof there are no audible changes found over time. It is obvious that Smokey has never used a Conrad-Johnson line stage like the ART which uses teflon caps or that he has used Nordost Odin or another cable that uses teflon in its dielectric. Both require fairly lengthy break in periods. So far, he has dodged the dielectric question and posted a schematic that *proves* that passive devices have some degree of non-linearity. No $hit. That's why the very best audio components use polystyrene, teflon and oil-in-paper caps instead of the electrolytics found in cheaper gear. Which does not prove that active stages are perfectly transparent. They aren't!

    The challenge is for him/you to prove that passive devices have less distortion / non-linearity than real world active stages like his EQ example. And he may not be aware of professional passive models like the Langevin Massive Passive. Does that make sense? Answer the questions directly with real answers. Text book theory is useless in the real world.

    edit: Here are some links regarding the use of teflon capacitors and one very detailed story of an upgrade and the break in experience.
