"Greenfield" flex conduit for DIY power strip?

Since I need a solid power strip that will not be moved around too much, I thought I'd pitch my idea. Using high quality outlets and ac plug:
Here's the layout:

copper gold plated wall outlet -> copper gold plated plug
copper gold plated plug -> "Greenfield" conduit with solid wires
"Greenfield" conduit with solid wires with hard connection to 2-Gang Weatherproof Electrical Box
2-Gang Weatherproof Electrical Box with 2 copper gold plated outlets.

This seems like a natural extension of the in-wall wiring with high quality electrical connectors and the least possible count of connectors for a power strip.

Conduit and elec box can be filled with sand if vibration control is needed or beneficial.

Your thoughts?

"The greenfield flex conduit will impact sound quality and is unnecessary in the home environment"

What's wrong with that one? I ask because it's the closest thing to what's in the wall. Exterior flex conduit can be used as the shield, directly connected to the aluminum box and ground, no?

I'm not sure as to the "Why's", but anytime a cables is encased - even if expandable nylon sleeve is used - it impacts sound quality. 

However,  on rethinking your specific application - since this is simply an "extension cable", into which the final power cable(s) will be plugged, it will probably be OK to use.

I try to keep all my cables as simple as possible - that means no pretty coverings

It really depends on how serious you are about sound quality.

I'm still not certain as to why you need the flex conduit in the "home envornment" - do you perhaps have pets that chew your cables?

Steve,

No pets here that will chew up my cables. I was thinking that since each audio component will still use it's own power cable, all that I need to do is provide an extension of the in-wall wiring that will terminate with a power strip for more outlets. One can get as creative as possible with how to make the ultimate power strip, the wire type and gauge, but my thinking is simple:
An equivalent extension of the in-wall wiring, with multiple outlets and as few as possible, good quality connections.

I see where you are going now - you are using the conduit to make using Romex as an extension cable comply to code - IT WILL NOT !

ALSO - romex IS NOT designed to be used in any type of conduit due to heat

Plugs are NOT allowed to be installed onto solid conductors ! They may break over time

Both ends of solid core wires and the cable itself must be fixed in position - as in the wall - not moveable

Might I suggest a slight modification that will actually sound better

1. Go to Home Depot and buy the single conductor stranded wire that electricians use inside conduit - get White, Black and green
2. Take the three wires and braid them (tighter the braid the better).
3. Insert them into the conduit for safety
Attach the box and plug as planned

The braided cable will result in a lower noise floor.

I think this method may up to code because the wires are stranded and the wires are protected by the conduit

But I would check your local codes first
