FWIW I have read on audio forums that steel conduit tends to take some of the air out of the music where aluminum does not. Therein why some like to use Romex instead of steel conduit.
Aluminum still gives you some RF shielding from airborne RFI entering the cable. Just install the MC aluminum armor cable like you would install Romex cable. Keep it at least 8" to 12" from existing parallel running branch circuits. Even further from lighting branch circuits that use dimmers and or transformer based LED lights. That includes the switch leg side of the circuit.

MC cable is manufactured in both steel and aluminum. “Steel-Clad MC” cable with insulated ground wire is the best choice for AV systems. It has twisted conductors that help reduce AC magnetic fields, however the steel jacket is what helps most.
