Just a small update to my review here. Still loving my bi-amped duel XPA-5 setup, with zero problems thus far. Love the sound, love the look.
I actually removed the silver trim pieces, and LOVE the way the amps look without them (you can't see the holes in the faceplate).

I'll post a pic. I have the LED's turned off, and the trim pieces removed, and to me they look better. When I take the pic, the flash may show the bolt holes in the faceplate, but under normal room conditions, there's no way you can see them. *I can't find my damn camera, that's the problem. |

Great review. It would seem logical that if each XPA-5 has a maximum rating of 1000 watts and you are using a 110V system, the amp should never draw more than 1000/110=9 amps assuming a PF of 1. Meaning if you have one XPA-5, a 15 amp circuit is fine. When I had my house built, I asked for a dedicated 20 amp circuit to the equipment closet. I have discovered recently while tracking down a ground loop problem that I do have a 20 amp rated outlet. The problem is that I have 14 ga wire which per NEC is only good for 15 amps unless it is run in free air and a 15 amp breaker serving it. Looks like I got taken to the cleaners.

If you have the opportunity to run the amps on 220 go for it. There are several advantages the most notable would be that it will cost you half as much to run them.
I currently run all my Emo gear at 220.
And any idiot that would ever recommend just swapping out breakers to increase a circuit should be avoided at all costs.
While Lowes and Home Depot both hire experience electrician's ( most notably retired part timers trying to supplement their incomes) the often have very low experienced people working in all the Dept's who's recommendations should be taken with a grain of salt. I recount numerous times Ive overheard some ridiculous information given to customers.

Could you explain that part? , mainly about the costing half as much. You can answer this in the technical section if you want to make it a topic. I'm not Mark, but... your electric meter measures the amount of current your house draws. At 220V any load (piece of equipment plugged into it) will consume half the amount of current that it will at 110V to generate the same power. Ohm's Law. So, using 220V means you will consume half the current, so your meter will move half as much and the power company bill will be correspondingly lowered. |

Long time reader - Question for OP - bourboncigars - you mentioned that you swapped out the Outlaw for the Emotiva - may I ask what model Outlaw? I, like the rest of the free world is awaiting the UMC-1, and I'm already dreaming of the XP-5 to replace my Outlaw 750. I don't think that a 20% increase in power alone would improve the SQ, especially driving 8 ohm Totem Sttafs - & I agree - wants always outpace needs. Thanks,

Congratulations nice setup. Get a measurement tool and see how many watts you are consuming. I think you will be shocked by how little the difference is at idle and with a dynamic movie such as the first 5 minutes of the matrix reloaded. Music is a different story. Movies are level mixed so THX certified amps can reproduce the effects as the engineers intended and the XPA series eats THX certified amps for snacks. 2 XPA5 should trip a 15 amp breaker but you will be deaf before that happens but room size is an important factor also. With big rooms you need more power. Keep in mind the caps can cover instantaneous power burst then they recharge. I bi-amped and felt it was worth the time one amp for the left and one for the right but I was after the extra separation. I still bi-amp the front with the ips1. I belive the XPA5 is around 50% efficient so one should be the limit to a 20 AMP circuit if you push it to the max. If you want to be sure?

My XPA-5 is amazingly cool all the time. Its a good thing don't get me wrong, but why?
I've had other amps you could cook on!!

So, using 220V means you will consume half the current, so your meter will move half as much and the power company bill will be correspondingly lowered. i apologize bumping this old thread, but i read this and coulndt leave it be. Your electric bill is not charged based on the amount of current drawn. Amps is a measure of coulumbs per second, which is the movement of charge. Your house meter actually measures kilowatt hours, which is power times time. Which gives you the end result of charging you per joule of work that is done in your house by electricity. So regardless of whether your running 110v at 10amps or 220v at 5amps, your using the same amount of power, over the same amount of time. Thus using 220v power doesnt actually save you any money. The caveat would be if the amps were to be more efficient at 220v, which i dont believe is the case. though at 220v your being more environmentally friendly due to the more efficient use of multiphase transformers outside your house, but thats done before it gets to your your meter so it has no effect on the cost. |

i apologize bumping this old thread, Bump away. It keeps my name up there in the spotlight. ;D haha, i just couldnt let people think that they could save money by running 220v, so i had to chime in, it was a conscience thing  and nice review, i have been trying to decide whether to get the mps2 or the xpa5 when i get my umc, though i guess my decision was made for me now, but all the reviews i read are making the decision easier regardless....unless the new reference 7ch amp is out not too long after the umc...mmmm that thing is gonna be amazing, though i dont know how it will be better than the xpa series, since its not using class h topology, i think its gonna use AB, but then itll just be a 7ch xpa but with less power since its spread oer 7 chs....but im not too worried, emotiva will bust out some more emo magic and make it awesome! |

I'm somewhat of a grammar Nazi, myself, and never knew this. Also, I thought the correct quote was "when in doubt, whip it out". ;D |

Haha, I actually read that article about improper punctuation and noticed they missed a period. How embarrassing! Maybe a spell check would come in handy as well! This is the proper spelling for apostrophe . Is Emotiva coming out with a punctuation for dummies manual to go along with their cables? I like the line" check yourself before you wreck yourself." ;D |
