dedicated circuit, flex conduit?

It has been recommended to me to use 10 gauge solid core romex for my future dedicated 20 amp circuits, (I plan on using two, one for digital and one for analog). My speaker manufacturer recommended using flex conduit to help RF, etc? My understanding is this cable comes with the wire already in it. 1. Can any of you relate your experience with flex conduit? 2. Do you need to ground the conduit? 3. Also, it has been recommended each circuit should have its own hot and neutral with each sharing a common ground amoungst them. 4. Is there anything else I need to tell my electrician?5. I have only 5 spots left in my panel for new circuits, would I benefit from a sub-panel?Thanks in advance for any input.

Personally, I would not worry too much about the concerns you have. Which is good for me since I could not answer them.

I would focus only on the following:

1. Obtain good aftermarket 10gauge 99.95% OFC romex-like house wiring.

2. Ensure that only the amplifier(s) have 20 amp circuits/lines and outlets. All others are 15amp.

3. Obtain aftermarket 20amp audio-grade wall outlets for each dedicated line.

4. Ensure that all is properly installed.

5. If you only intend to install two dedicated lines (why not three or 4?), then you might want to consider placing ONLY the amplifier on the dedicated 20amp line, the preamp on the dedicated 15amp line, and the digital on another non-dedicated circuit.
