Thanks for the reply, Caelin, but you misunderstood my questions, so I am going to rephrase them.
1) In the situation where one already has burned-in Zitron cables, do the cables need to have current through them for a minimum amount of time to perform their best? An example of this would be the Typhon. When inserted in the system it needs up to 5 days to reach top performance. I used to have solid state amps that were on all the time (or at least in standby), drawing at least some amount of current through my Alpha HCs. I noticed that if I switch power cables - or simply unplug them and plug them back in again, it takes a number of hours for them to truly sound their best (or at least that's my perception). Now that I have tube amps that are only turned on when I listen (therefore do not draw any current when I'm not listening),
