High Current Outlet for Amps?

Multiple 20 amp circuits will do the job, yet I chose to install multiple 30 amp as it was not significantly more expensive. Higher gauge Romex and 30 amp circuit breakers are not significantly more expensive than the 20 amp stuff. Labor cost should be the same.

As for plugging your amp(s) directly into the wall, it depends on your particular conditioner. Let your ears be your guide.

This is going to depend on the efficiency of the speakers, SPL, and what operation class the amp uses.

One thing is clear tho -- a dedicated line is close to the last thing you want to do to improve SQ.  if you are doing a remodel anyway, then just go ahead - get bids for the different options first.

I had a 30 amp line put in for my system and use a PS Audio Premier Power Port for the receptacle.

As Dave said above, the cost difference between the 20 and 30 amp circuit is minimal.

Well, my concern is not cost because the current remodel requires new circuit and cable anyway so it's just something quick for the electrician and cost me next to nothing. Now, the 30amp outlet plug is different shape than the ordinary 20amp? 

As for not going through power conditioner, let's put aside sound quality but safety? Some amps draw so much power that condition may actually do more harm than good to the amp? Is this accurate?

The AudiogoN archives has many, many threads about plugging the amp directly into the wall vs a power conditioner. Having a dedicated circuit is one of the best solutions for improved SQ. It would be even better to have 2 or 3 dedicated circuits with the outlets clustered relatively near the equipment rack. This would save costs on the lengths of power cables. One circuit would be for digital only (DAC, Streamer, Laptop, TV, etc). The other(s) would be for analog - perhaps, future tube monoblocks. A conditioner or conditioners could easily be added later to each circuit if desired.

Re: safety If everything is up to code, circuit breakers will do their job. If the electrician is licensed and has a good reputation, then all should be copacetic. Most consumer electric space heaters draw more power than a stereo amp or power conditioner. The amount of power drawn by an amp or conditioner is determined by its design. A relevant formula is: watts (w) = volts (v) x amps (a). Two thousand watts draws 16.6 amps @120v. So, a common household circuit of 20 amps should be plenty. If the circuit is a very long run from your rig to the utility box then there will be some voltage loss along the way. But, very few amps or conditioners draw 2000 watts.
