[sdiy] Studio Electrical Wiring Questions

[BrightBoy]

Hopefully this isn't off topic -- let me know if it is....

I'm on the verge on finally building my home studio in a large room in
the
basement and I'd really like to achieve the lowest amount of
hum/hiss/buzz 
as possible without spending thousands and thousands of dollars....

A friend of mine recommended that I have a second 100Amp service brought
to the house which would strictly power the studio with it's own
seperate
isolated ground (attached to a seperate grounding rod).  This would
involve
adding a 2nd power meter, breaker panel, etc.

Is this really worthwhile or not????

If so, does it even meet the NEC????

After reading over Article 230 (230-2) it seems that it might not be
allowed....

Or would I be better off just wiring the studio to the existing breaker 
panel and getting an Equi=Tech balanced power unit????

Will the Equi=Tech system prevent other loads in the house 
(refrigerator, furnice, dehumidifier, etc) from dirtying up the power 
to the studio????

I've also been told by another electrician (Larry Hendry) that if I run 
a 2-pole 220VAC circuit to the studio (from my existing breaker panel) 
and then split it into two 110VAC outlets I should be able to acheive 
lower noise figures than running two seperate 110VAC circuits
(especially 
if I load balance between the two outlets derived from the 220VAC)

Sorry for all the questions, but this is fairly confusing even for an
electrical engineer....

Cheers,
