Know a Good NYC Electrician for Dedicated Lines?

We are ready to take the plunge and install dedicated lines. I'm on the 14th floor of a 1960s Manhattan condo (174 units), so there must be all sorts of bad karma coming through the current lines. I'm hoping running dedicated from the breaker boxes will bring at least some improvement.

Can anyone recommend a good electrician in NYC that has done this work for audiophiles? Thanks.
