What does it mean when people are saying to install a 20 amp 230 volt circuit? A 240 volt circuit requires a different plug end to the wall socket in the USA. 230 is actually the motor or transformer rating. 240 volts is the circuit rating so that with voltage drop you don't go below the 208,230 motor ratings. It just seems silly to me to install a 240 volt circuit when your amp is going to use a transformer to bring the voltage back down to where it needs to be. Your only gain is the voltage drop from your breaker box to your receptacle which is hardly an issue with any of these amps. If Emotiva wanted to, they could get by with a pretty small guage power chord. At 120 volts, if the power chord is 14 gauge it is probably better than the circuitry after the transformer which will drop amperage and up the current which requires much bigger wire. A 14 guage power chord would probably be more than enough even on the 20 amp circuit. 20 amps circuits require 12 guage wire unless the run is very long. This is from your breaker box to your receptacle. I am sure it would be more than fine for 14 guage on small run from your receptacle to your amp. The reviewer probably mentioned the need for a 220 volt circuit because he would like to stay at home and do resistor tests for multiple amps into one socket all day long. Other wise it would be very hard to pull that much juice from any of these amps. Any 2 amps will shut down long before the circuit breaker trips, especially if you have a 20 amp circuit. Thanks for that post. It clears up a lot of questions and "sets the record straight" from a technical standpoint.   |

I don't know the gauge off hand, but I did buy some ac cords from mono-price because they sell them in one foot increments. I seem to recall they were just a few dollars, and neatened up my set up... .

Does anybody use them? Im not trying to open a can of "snake oil", just wondering. The power cord I received with my XDA was thicker then either of the power cords I received with either my XPA-5 or 2. I'm not looking to spend serious money(>$150). It seems to me, for all the juice the amps need, they would have a thicker cord. It's been my experience with other amps(Parasounds,Adcom,Anthem,Outlaw)that they all came with thicker power cords. All opinions are appreciated. Here's what I use on all my HT stuff. My fridge and microwave too... blog.ultimateavmag.com/ultimate-gear/nordost_odin_cables/ |

I had a thicker cord from another device already, so when I got my XPA I just used that. But I guess it wouldn't hurt to have a bigger cable especially if you are going to be pushing the amp to the limits. I'd rather trip a breaker then light my house on fire because of a power cable that was insufficient. Don't confuse a thicker power cord with a thicker gauge power cord. I had a CL2 rated 14AWG power cord (which I never saw before nor ever saw again) that was thicker than another that was not rated for in-wall use and was 12AWG. Make sure you look at the casing. Sometimes it can appear thicker because the outer casing is just thick. BTW, I have the Emo power cords because I a.) like the look and build quality, b.) were the right price, and c.) my receptacles are exposed where they get plugged in and create a nicer "finished" look. |

Yes, I use them aftermarket cords. Them USA plugs don't work in EU, do they? ;D I both got €20 and €100 worth. The expensive ones look nicer, but I don't think they perform better. In fact, it surprises me that the various cords I have don't really "stick" to the devices like they stick in the wall socket. They are looser than the interconnects. Erwin, nope but your solution could be to move the house/dirt and all to the USA, but prices are going down here so be careful [Grins]... Did those electrons really travel faster with those after market cords... ;D I am a Gauge Man vs. Length of Run for Voltage Drop, and look at the Insulation Dielectric like TFE - TEFLON being one of the best insulators, to minimize any EMI/RFI impinging upon the AC Pwr. Cable, plus like double shields, but since the ground on the XPA-5 is not there, not a really big issue unless it's tied back to ground at the power wall recpt. being one end grounded. |

THICK!!! Kraemer -- where did you get that AC pwr. cbl. from? Specs? Cost? ;D Tks. |

I am using a 3ft Audioquest NRG-2 power cable on my XPA-3; I used the stock Emotiva power cable for my TV now as it was a better cable then the stock Sony. I switched out my amp, avr and sub woofer with Audioquest NRG-2 power cables and have noticed an inmproved picture clarity and a cleare more refined sound. Might all be in my head, but I am okay with that! |

I do mine too look good and function. I started mainly because I hated too long or too short of a power cord. I can make any length I want with the Belden power cable I use.

I've always found it interesting that people buy these thinking they help. Why does the Emo cable improve anything and why is the last 3 or 6 feet of the ride important when you don't change everything in the wall including the outlets, wall wiring, meter contacts and wiring all the way to the transformer??
Its almost like putting six feet of glass lined pipe on your fawcet and now you are expecting the "dirty water" to taste better........ WUT?

Wow, those are VERY Nice AC Cables for sure (7 AWG), but at $70 for 1 Meter, I need to really see if I can justify them. What I did not like about them is they use PVC, where my readings state that TEFLON then Polyethylene, and PVC is out for a great Dielectric polymer to minimize EMI/RFI interference impinging upon the AC Power Cable. Of course, AIR is the best but not possible, so the mfg's. put a polymer into the cable. I personally just don't think I could hear any difference ... but certainly they will support all the current the wall could deliver at 7 AWG with almost no voltage drop in shorter runs of a few feet that would be concernable. |

Nezff - what is the AWG that your using and what is the polymer in the cable (TFE, PVC, etc.), and the type of shielding (two? and type like braided or foil, etc?)? Tks, Den |

Jayzus H. Keeriste, the Nordost Odin power cord is $11,000 for a 2 ft. run!!! Nordost must be laughing all the way to the bank every time some dumbass "audiophile" "invests" in one of these...

Do power cords make a difference in sound??? I have no frackin idea. ::)Some say yes, some say nay. I'm very skeptical but I'm gonna experiment and find out for me self. Pops always said dont believe everything you hear or read. I did lots of testing with speaker cables and ic's and discovered they do make a difference so only one way to find out about power cords. I have stock Emo cords, two X series cords and I'm gonna order some Pangea cords next week. If I don't hear a difference, I'll at least have some pretty cords. :-).

Plus my Revelation IC's are not shielded so some shielded power cords might not be a bad thing.  |
