HELP wiring - Romex 10 ga. to cryo or not?

Hello and thank you in advance if you are perusing this plea for advice.

The wife and I are currently building a new home, and I will be having 5 dedicated 20A circuits run to the stereo room.

I have talked to quite a few people about what to run, either 10 gauge Romex, or 10 gauge Romex that has been cryo treated.

As you may have guessed some lean one way, others another. I will have to move fast, as the builder will most likely start the wiring in the next few weeks.

I know I will at least go with Romex, 10 gauge, solid core copper. I will try to keep the length of Romex runs very close in length (was told this will help reduce ground loop hum). I will be using Porter Ports for the receptacles. I will also see if the electrician can give me an isolated/dedicated ground for the 5 dedicated lines. (think that is what it was called...) The 5 20A lines are all supposed to be on the same leg of the breaker box, at the top... AC units, refrigerator, etc. offset on the other side.

Please advise if going with this same wire cryo treated will affect the sonics...

my system link should be listed next to my moniker.

Thanks again for the help!
