You may know more than your electrician about audiophile needs- I’ve found this to be the case in the past. The electrician will (or should) comply with Code (as written in the local jurisdiction), but you can and should take a look at some of the threads where @jea48 has discussed best practices. Code is, in a sense, a minimum, and aimed at safety, not sound.
I just went through a new install in a ’new to me’ house. I used a commercial electrical contractor, who seemed to ’get’ some of the stuff better than an ordinary residential electrician (nothing against ordinary residential electricians).
The National Code (assuming you are in the States) keeps getting updated. Since the last time I went through this (having an electrical subsystem installed for a dedicated room), Code now requires arc-fault breakers, wiring the panel to permit them (something I can’t speak to but others might), and I believe childproof receptacles (which, as far as I know, aren’t to a high standard --maybe there is a hospital grade one, but your electrician might give you a pass on your existing outlets). It also depends on whether the work is permitted and requires inspection. (Mine did, it was a large amount of work, involved a big isolation transformer, etc).
If you like your outlets keep your outlets. FWIW, there are unplated Hubbell hospital grade, like the ones Albert Porter sells.
