Welcome to the Lounge. It should work fine. At least as good as the stock one that comes with the amp.  |

These products are usually lower quality then the one I posted below. I make my own powe cables with “clone” hardware I order directly from China. Depending on company the quality control can really vary, especially from smaller merchants. If you want a sure thing spend a few more bucks and be sure that the plug won’t burn your house down... www.amazon.com/Pangea-Audio-AC-14-Powercord-Meter/dp/B0030ERI1W |

The cable in question, as linked, has NO information that is useful to me. I'd personally either do a DIY Belden based cord or simply send off for one of the 14se Pangea cords which get reasonable reviews. I think Signal Cable also sells a reasonably priced cord. You might find some SLIGHT advantage to a shielded cord, like one of the DIY Belden www.audioasylum.com/reviews/Cable/The-Bolder-Cable-Company/Type-1-AC-power-cord/cables/32648.htmlThis is an extensive review, but may give you 'food for thought'. You won't save much $$, if any, over the cheapest store-bought, but Will know exactly what went into the cord. Most DIY guys should be able to pull this off. |

I am not going to start the lore of the power cable stuff. However any IEC standard power cable such as the one that comes in the box will work fine with your XPA-2. If you need a longer cable etc. You find them just about anywhere. From stock to "special". It is really up to you. As long as it is IEC standard, you can't miss. Enjoy!

Too late to 'start the lore' of power cables. This is really one of the 3rd rail topics of audio and making hard recommendations is the easy way to get vaporized.
Chances are very good that the 'cord' that comes with the amp is one size TOO SMALL. It might even be a 16ga, which to ME is an insult for a high powered amp.
If 16? An upgrade to 14 would be nice or perhaps a 12ga.
And DIY is not out of the question on something a simple as a power cord, though some aruguing exists about the need or benefit of a shielded type.
From a simple electrical standpoint, it makes sense to have a cord capable of the continuous (worst case) current draw of such an amp as the XPA-1 or -2.
I'm not recommending a HUGE outlay, but rather a reasonable upgrade over the stock cord which on most amps are near to being a throw-away item.
The cable linked in the original post should be AVOIDED, IMO, since they do NOT list conductor size, which is one of the fundamentals. Also, using a good grade of
OFC (Oxygen Free Copper) helps both conductivity and reliability.

All I know, Is that I, and a whole band always just used the power cords that came with our equipment.
They worked just fine with fluorescent and neon bar lights. And we made the music.
So I would assume that the stock cord That came with my Emo amp would work just fine replicating it. Just opinion of course.

Except for Measurables, like cable gauge, resistance and reactance, I'm fairlly agnostic about cable, including power cables. Others make grand claims about the Insulator, like Teflon or PVC or  However, in all fairness, their exists a substantial body of evidence which some might call 'Anecdotal'. All sorts of improvement claims relative to the 'stock' power cord have been noted. That being said, I doubt anyone knows what cables are shipped with EMO amps. Does EMO brag about this or otherwise let the end consumer know? Or do they count on 'cable is cable' and that's IT? I believe in a conversation with Richard Schramm of Parasound, he indicated my A23 came with a 16 ga power cord. He indicated that a 14ga MIGHT sound better but would defiantly improve instant current capacity TO the power supply.. I don't think I need something the size of a Stuffed Python but rather just a Little Larger gauge. With the -1 series from EMO, I'd want 12ga and a dedicated 20 amp service for a PAIR of such amps. But that's just me. |

This is perfectly capable of reliably providing all the current an XPA-2 Gen.2 could possibly need and then some. |

When I run my Chop Saw a LOT when doing a major build, I use a 25' 14 ga. extension cord. The PLUG end can get warm after an hour or more of cutting. The saw, by my Kill-A-Watt might be 7 or 8 amps no-load, after start-up kick.
I don't argue what you're saying, Cogito.
But the counter arguement MIGHT be that it's not always about meausreables. The real vehement types might talk about the 'sound' of the cord and than go off on insulation type and shield or NO.
This is all past my pay grade and I present the information only as what others think and without warranty, express or implied.
One participant here is fond of pointing out how much current a 15amp breaker can pass for short time periods. I don't know the 'burst' current NEED of any of the -1 amps but at least one of 'em was rated with a 20 amp circuit.
Have fun, no matter what.
I'd offer to do a Group Buy of DIY power cord parts, but I know how far that'd get me!

Yes it can. The important part is making sure that it is an IEC plug so that it will fit your Emotiva amp. I have to agree with GearHead2003. It's hard to beat a Pangea powercord when it comes to sound. Others may disagree, so why not find out for yourself. |

Monoprice and/or Parts-Express sell some 14 ga. power cables that I recommend for their price. They're heavy-duty and inexpensive. If you're in a noisy environment (most aren't) then shielded cables from Pangea or Emotiva are justified.

Never does it cease to amaze me....the ENDLESS parade of thread discussions with enthusiasts looking to replace the electrical cord supplied by the DESIGNERS of the amplifier in search of? Why not ask the manufacturer if it’s necessary, meaning if something in your installation has you concerned that the cord ain’t doin the job. An outfit like EMO. will yield you a straight answer from tech. Support. (save your money 💰) A person hot to open the wallet will not hear that and do it anyway, of course. One things for sure, there will always be a plethora of suppliers out there more than happy to tell you what you want to hear! Bill |

Hi 405x5 - You miss one thing... As equipment migrates through the used market, it is not (at all) unusual for the original power cord to have been lost or substituted with something else. I agree with you wholeheartedly that the stock cord is more than adequate in 99.9% of applications, but what got substituted by a secondhand seller may or may not be. For the price of a Parts-Express 14 ga. power cord, I don't ever need to wonder whether the cord that I got with a used power amp is sufficient or not. |

Hi Boom....and Happy New Year 🎆 (almost) Well, my head wasn’t in the used market place regarding this last thread, but that being said, yes sure, a used amp. With a questionable cord on it valid enough to consider. Ironically, the last 3 amplifiers used, I sold off all had hard wired power cords rather than the detachable type. Bill |

I'll always maintain that a 16ga power cord issued with a -1 series amp is Inadequate. Even 14 would be a help.
For an amp with such capabilities ANY excess IR drop is Too Much.
That being said, you do NOT have to spend a bundle. The Pangea offerings are pretty good while Signal Cable goes a little 'upmarket' from that.
You could REALLY go nuts and spend 6 digits for such a cable, but I personally must draw the line nearer the 'entry' cost end.

Scenario: a few Emotiva amp designers, doing all the math and research building a very hiqh quality amp. We're talking bullet proof case that would survive a nuclear bomb, and the whole 9 yards. They spend weeks tweaking this and that, get it "just right". Measurements are as "best in class" as they can get. Then on the way out of the lab for lunch one day, they realize they need a power cord yet. A) Do they provide a properly speced power cord which doesn't negatively affect the blood, sweat, and tears they pored into that amp? Or, B) They toss in a power cord that isn't up to the job to save 10 cents on some copper wire? Take your time, I'm sure you'll come to the correct answer |

Ah, copperpipe - You're an optimist... The design engineers don't really get to spec the power cable (or much of anything else). The marketing boys do. They're the one who want the amp to meet a target price so that they can sell the most at the greatest profit. The qualities of most EVERYTHING in the amp (including the power cord) are subject to cost constraints. This means that if a cost-compromise is proposed that will affect only 1% of the purchasers, the cheaper part is used every single time. So your amp won't actually exceed its specs due to the limits of the power cord or heat sinks (for example)? The marketing boys don't care - and they have the final say. Now the hypothetical case above is highly unlikely - power cords are cheap. But the principle is sound for EVERY phase of component design. Why don't Emotiva amps have half-inch-thick solid milled aluminum faceplates like some "high-end" amps? Cost. Why don't Emotiva amps use name-brand exotic parts like some of the "super-amps?" Cost. Why don't Emotiva amps run much cooler due to their adequate-but-marginal heat sinks? Cost. Why can't Emotiva amps put out twice their wattage into four-ohm loads? Cost. Why don't Emotiva amps use the jewelry-like, heavy-metal speaker connectors that some other expensive amps use? Cost. Now some of the cost compromises (chassis and power cords for example) probably don't really affect the sound at all, which is why Emotiva can compete with many amps that cost more. But some of those compromises - particularly in resistor, transformer, heat-sink, and capacitor qualities and quantities are definitely audible. This is why I'd rather have a Mark Levinson, McIntosh, or Audio-Research amp, for example, than an Emotiva. But one pays their money and takes their choice. Within limits, you get what you pay for. But yes, if the marketing boys could save 10 cents on some copper wire, they WOULD do it provided that the amp still met its specs with the cheaper cord. Cordially - Boomzilla |

“It's hard to beat a Pangea powercord when it comes to sound. Others may disagree, so why not find out for yourself.” Gotta love 💕 it! All the ingredients of the classic sucker punch are well in place here. Bill |

I replaced the power cord on my Emo SA-250 with a 7 gauge Pangea AC 9 SE power cord, and the difference in SQ was substantial enough to dissuade me from taking any more looks at the stock power cord. That stock power cord is now buried somewhere deep inside a box of discarded stock power cords; it is buried so deep that I doubt whether I could locate it again, were I to even try that, which I won't, unless I decide to sell that SA-250. However, in that case, any one of the discarded stock power cords would do, and one of them will ship with the sold SA-250, and I bet the buyer would be satisfied too, and none the wiser. But my SA-250 isn't going anywhere too soon. as I am not selling it, so all this speculation is just that, speculation. If you are skeptical, and you have an emo amp, or something comparable, and would *dare* to try out an inexpensive experiment with an open-mind, you could check out the Pangea AC 9 SE and see the results for yourself! What have you got to lose? If you do not like what you hear, or if you do not hear any difference, you could always resell the power cord very easily, and go back to enjoying the satisfaction of thinking that you have always been right about those damn power cables. However, if you do hear the difference (as I am sure you will, provided your hearing is unimpaired), and do enjoy it, you would have made an interesting discovery for which your ears and wallet will thank you... What is the harm in that? Talking about open minds, it has never ceased to amaze me how tenaciously and stubbornly some folks in this hobby can hold on to beliefs or opinions which they deem to have been "proven" conclusively by some "measurement," or set of measurements that they consider to be "scientific." Isn't "science" supposed to be founded on a spirit of open-ended experimentations in which "truths" held to be sacrosanct one day, may be completely debunked and/or falsified the next day...? Do the tenacity and stubbornness with which certain "skeptics" and "objectivists" hold to their opinions in audio not resemble sometimes the very "dogmatism" of fanatically held beliefs that is meant to belong in the province of religious practices? Well, I am not trying to re-kindle a tired firestorm here over one trivial experiment with a cable. I am just trying to share an experience that some may or may not find useful. Oh, and lest I forget : YMMV Happy New Year to all. |
