Isolated or dedicated lines for audio ?

.
One more note. It is well worth it to buy the wiring and send it off to be double cryoed (www.cryogenicsinternational.com) before installing the wiring. It is a great improvement over non-cryoed wire. Since this is a one shot deal, you should do the cryoing since you will not want to re-do the wiring later.
.
Keep one more thought in mind. The dedicated lines will take time to break in just as would any interconnect, spearker wire or power cord. A neat trick is to get the wire, get it cryoed and then terminate it with a male and female plugs and then run your refrigerator with the wire until you install the wiring (the longer on the refrigerator the better, 3-4 weeks would be great, longer would be better).

Cello, can you shed any light on this?

For wire, does flexing the wire after cryoing undue the effect? For example, it would be impossible to pull 10 ga solid core AC wire through EMT with bends without considerable flexing.

I do not have any experience or knowledge about the effect of pulling wire on the Cryo effect. I do know that any time I move power cords, interconnects and especially speaker wires around a bunch (flex etc), it takes a few days for the sound in my system to "settle" back to its normal sound.

Maybe someone who has experience with this can chime in.
