so I appreciated that paper had some sound logic (pardon the pun) from one
side of the issue, I'm not taking it as the final word at all don't worry.
I'm fortunate enough to be able to do this project but only if I do the
majority of the construction myself so there ain't no Richie Rich spendin'
going on here at all... :)
I think in the end I'm leaning toward going with Romex (which does comply
with code here). The fact that this space is larger with a higher ceiling
to route the wiring through than what I had before will enable greater
distances from the single coil instruments generally.. As I said in my
original post the single coil noise was only a minor annoyance but I
thought it prudent to at least ask for some input before starting from
scratch. My gut feeling was that it was not worth shielding it but I
appreciate what everyone has shared and that they have taken time to
reply.
If you told us some more about what you're trying to do, people might be
able to offer low-budget/ good value suggestions for your studio
electrical system. For example, separating power and signal conductors
as widely as possible, using larger gauge wire for your feeder and/or
branch circuits, and implementing a star-grounding/ isolated grounding
scheme (wood framing, plastic boxes, and Romex should give you this for
free). (Of course, all of your audio equipment and cabling needs to be
properly designed and constructed so as to avoid ground fault, EMC, pin
1, balanced/ unbalanced, etc., and other electrical/RFI issues.)
If this is a home studio fed from the same panelboard that feeds your
house, you might find that all the other loads in your house (and/or
your neighbors' houses) are causing electrical noise problems for your
audio systems. You might want to think about a feeder to a dedicated
audio sub-panel now, and possible isolation transformer or other
conditioning later as needed:
