High Current Outlet for Amps?

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.

The 20 amp receptacle is the same as the 30 amp one!  No difference at all.  You are just running 10 gauge wire connected to a 30 amp breaker in the service versus a 12 gauge wire connected to a 20 amp breaker.

All of my system components are connected to a PS Audio Premier Power Plant regenerator except my power amp which is conditioned by a PS Audio Duet and Humbuster III.  Works great for me. YMMV.

Agree with steakster about putting in more than one line, especially if everything is going to be plugged directly into the wall receptacle.

"Now, the 30amp outlet plug is different shape than the ordinary 20amp?

I used 20 amp receptacles. 10 years with no issues. The extra amperage is paramount to adding headroom in my mind. Instantaneous peak current draw is what we are looking to address, so very little risk of overloading a good 20 amp receptacle due to millisecond current peaks.

"As for not going through power conditioner, let’s put aside sound quality but safety?"

Safety? If you mean surge protection, IME conditioners with surge protection that don’t limit current are expensive. Since you are starting from scratch so to speak, investigate addressing surge protection at the breaker box per another recent thread here. No conditioner will protect against direct lighting strikes and the whole surge protection concept is best addressed at the breaker box IMO. 

"Some amps draw so much power that condition may actually do more harm than good to the amp? Is this accurate?"

I would modify that statement to say that "Some amps draw so much power that some conditioners may actually do more harm than good to the SOUND."

I have used many high-current amps plugged into my SR Powercells and find that the sound is better than way, with no constriction of dynamics . Other conditioners, but not all, limit current so are best bypassed with amplifiers. Another recent thread on this here as well.

It depends on the class of amplifier, as randy-11 stated.  With typical class AB amp music power is very low, being only a few percent of peak power (unless you listen to sine waves).   It is because average 50% of loudness is only 10% of peak power, not to mention any gaps.  In spite of low average current demand it is drawn is short spikes of very high amplitude.  For that reason any impedance in series (many conditioners) cause voltage drops and reduction in dynamics.
