New construction bedroom circuits generally have AFCI breakers which might be what caused the breaker to trip with that load sensing an arc. My 20 amp breaker runs close to its rated capacity with all my gear and has never had a problem. Yep that would be the breaker type. Now if you read emotiva's recommendation for multi channel gen 3, they recommend a 220 line. Not saying it's a have to have but I will put one in. I have extra wire, and the 2 pole breaker is cheap. If I leave it the way it is now, someone will crank it while I am at work and I just don't want any problems down the line. Back on the topic the gen 3 xpa5's sound floor is black, no hiss, no static, just perfect. |

I would also think it would depend on its configured if it's 2, 3, 5, or 7 channel since like you said the more channels the higher the power draw. Are you using the trigger output from the receiver to remotely turn it off and on? Yes |

Yep, I have a commercial vacuum cleaner that trips every single AFCI breaker in the house at start - works just fine on regular non-AFCI 15 amp breakers. I guess when Emotiva says the Gen 3 power supply reacts quickly to current demand they aren't kidding! |

You can run two XPR-1s on a single 20 and not have any worries.....

It has already been asked, so I'm now going to insist that if you don't have comments or questions of actual owners of XPA Gen 3 power amplifiers then please refrain from posting off-topics subjects. Thank you to all members for your cooperation!  Just for full disclosure, I've deleted off-topic posts up to here. |

I am curious though, have any other gen3 owners had problems with breakers at reference level?

I am curious though, have any other gen3 owners had problems with breakers at reference level? discussion of breakers wearing out: diy.stackexchange.com/questions/15286/is-there-a-lifetime-failure-count-for-a-breakerI'd replace 'em after 5 trips. Breakers can fail OPEN or CLOSED. Whole House surge protection might help in this regard. Also, I'd get a Kill-A-Watt meter and MEASURE current draw / power and Power Factor of the amp. You can also measure voltage SAG from idle / no sound to whatever the heck 'reference level' means to you. It always cracks me up when somebody buys a KiloWatt amp and runs it on a 15 amp service with a 16ga power cord. They are getting about 2/3 of what they paid for. I note NO circuit current requirement for the G3 amps, which SHOULD mean 'ok with 15 amp', but for 3 channel and above, I'd TRY to have a dedicated circuit of 15 amps and for 5 cchannel and above, I'd make it 20 amps. The XPR-1 /2 owners are prime offenders in this regard. |

Quick reply, Fast.
First, when you say 105db, if that is peak, it is very loud. maybe 85 to 95 db continuous. \
If you mean 105db continuous, that's 115 to 125 db peaks which is well into distortion range for MOST speakers. and Ears.
87db sensitive speakers would need 64 watts for 105db continuous and 640 watts for 115db peaks. 125db peaks are out of the question for the amp and probably for the speakers.
Again, not only would I urge you to get a Kill-A-Watt meter, but also head over to the local RadioShackup and get one of the cheap db meters. Not the last word in accuracy, but fairly
repeatable and will give you a reasonable idea of how loud you're really getting.
Cross that data with the Kill-A-Watt measurements and you're golden. The Kill-A-Watt? Maybe 25$, so also not too much loot. With the system at 'reference level' I'd be curious as
to current draw, power factor and how much the line voltage dropped from no-load.
Your original suggestion for a 220v line? I'm thinking about that and at first pass it's a good idea.

I am still puzzle about what ir this topic about. Can someone please explain to me so I don't go off topic? This thread is only semi-off topic. fastmatt popped a twenty amp circuit breaker with his new Gen. 3 XPA-5. So everybody is speculating on what could have caused it. Meanwhile fastmatt has said that the Gen. 3 amp sound floor is black and sounds more like his XPR-2 than his XPA-1Ls. Fuller while a bit more rounder in the treble than bright. We're waiting to see if popping circuit breakers is a trend for the new Gen. 3 amps |

Also Fast402 has said that his Gen. 3 XPA-5 is more musical and detailed than his Adcom GFA amps.

Adcom amps are kind of too detailed for my taste. I hope is a good kind of detailed...

I am curious though, have any other gen3 owners had problems with breakers at reference level? I have had my Gen3 amp since April 13th with no issues. It has not thrown a breaker at all. The Gen3 is on the same 15 amp circuit as my Denon 3805 avr, Oppo 105, and one of my Goldenear Triton One 1600 watt subwoofer amps, along with a handful of other electronics. There is no AFCI breaker on that circuit. I just played Rush's 2112 Overture using my RS digital SPL meter with continuous readings ranging from ~85-98 dB once the drums kicked in with no issues. I turned it down after the Overture as that volume is just a tad too much for my ears. |

eiffel62 - How does it sound compared to what you had previously?

Nice choice. Der Trommler I'm sure would also be simply amazing.
Glad to hear no arc fault breaker.

eiffel62 - How does it sound compared to what you had previously? The reason I have not posted in this thread is because this is my first Emotiva product so I have no prior Emotiva amp to compare. I did get a temporary Crown XLS v2 1502 class D amp (300 watts/channel) to power my GoldenEar Triton Ones late last year and that was my first power amp. As one might expect, the Gen3 betters the Crown with much lower noise floor, better separation of instruments, and quicker, tighter bass. I look forward to retiring my Denon 3805 AVR with a surround processor so I am definitely interested in the XMC-1 or other processor as with the AVM 60 in that price range having the 3-D sound codecs, room correction, and balanced outputs. I am aware of Dan's announcement of the upcoming upgrade to allow for Dolby Atmos & DTS-X for the XMC-1. So I am in a wait'n'see mode for that. I wanted a 3 channel amp to power my all Goldenear LCRs and they do indeed sound wonderful. I plan on getting another Gen3 to power the surrounds and rears or maybe the height channels if I go with the XMC-1 and 5.2.4 ditching 7.x.x. The Crown amp now powers the two surrounds and the Denon avr is handling the rears and the volume control. Since the two competing surround processors are in flux, I have time to upgrade my surround speakers from my aging DCM TF-600s to the Goldenear Triton 2+ which has 2 powered subwoofers each and then will have plenty of subwoofers for my HT setup, essentially 5.4.4. |

I think you'd love the XMC-1. I upgraded from a Denon AVR-4311, and have been very happy.
