15A vs. 20A power cord questions

I'm installing dedicated 20A lines with 10AWG cable and Furutech GTX-D 20A wall receptacles. I am currently using the standard IEC power cords that came with my Rogue Cronus Magnum and VPI Scout 1.1. 

I rather not upgrade the power cables at this time. I would like to see the effect the dedicated lines and outlets have first. Are there any issues with running 15A power cords into a 20A outlet and line? Would a 20A power cord possibly sound better or is it just a matter of the blade orientation?

Where is the amp plugged into?

Not the same duplex receptacle as the CDP?

@jea48 currently same receptacle as the amp, although I am running the fan in the amps position.

asp307,

I would plug the amp into the other duplex receptacle, jmho. I would have both the phono preamp and amp plugged into the same duplex. Analog and analog go together just fine.

The CDP would be plugged in the other duplex receptacle. Problem with both the CDP and amp being plugged in the same duplex receptacle, there is a greater chance of digital hash/noise traveling back out on the CDP power cord and re-entering the power cord and power supply of the analog power amp. (Coupling the digital CDP power supply to the power amp's power supply.)

Granted both duplexes are fed from the same branch circuit but they are separated by what ever the lengths of the two spurs of NM-B cable from the junction box below the floor to each wall duplex receptacle outlet. Every little bit helps.


You may not hear any difference the way you have it now. After you get the four receptacles of the two duplexes burned-in you could then experiment having both the CDP and amp plugged into the same duplex receptacle and then separate them as I described above. Listen for any differences in sound.

@jea48 Thanks, I am only using the CDP for burn-in. I think you answered another question though. I have two duplexes and 4 receptacles. Do I need to burn-in each of the 4 receptacles. For instance, just because i’m running a box fan in one receptacle, that is not burning-in the entire duplex, correct?

Regarding the phono-pre, this is down the line. I currently only use an integrated and a turntable. Which duplex should the turntable be plugged in to?

Will a burned-in/not burned-in receptacle make a difference for the turntable motor?

asp307: What I meant was their first point at which I considered them and the sound profile of the system with them, fully broken in. I heard another increase in sound quality somewhere in the 1000-1500 hour range; after that, no other increases in quality/etc...were heard.  500 hours with a duplex receptacle is easier to put on than some would think. It does not take 6-8 months as mentioned above "assuming" you connect constant current drain devices (amps, house fans, etc..) to them and leave them powered on 24x7.
