Wire for new Equi=Tech7.5WQ sub-panel

I just picked up an Equi=Tech 7.5WQ wall panel.

I plan to run seven dedicated circuits which equates to 400 ft. so the high price stuff from LPS Labs, Cardas and the like will be out of my budget.

Is there anything a little better than the 10 AWG Cryoed Romex from VH Audio and the high dollar stuff?
Buy whatever wire you want and then send it to Cryogenics International, Scottsdale, Arizona to be cryo'ed at $9.00 a pound. They wave treated multiple cables for me.
