Well I've given in to the desire of having a mate for my XPR-5, so I just ordered an XPR-2 at the exceptional sale price. Once I have it up and running I'll comment on the heat it dissipates, but given how cool my XPR-5 runs, I'm expecting the same. I'll now have the Reference level power amplifiers in place for the future Reference level speakers. Damn Emotiva for turning me into an audio junkie! ;D My XPR2 does not run as cool as my XPR5. Its not even close. Not sure if I have a defective one but the XPR2 is warm to touch and puts off a decent amount of heat during use where as the XPR5 is very cool when being ran. I dont have a clue about y this is but would like someone who has both to chime in before I call support. If it is meant to run like that, that is fine by me. But if it is supposed to run cool like all of the other XPR series then I may have a bad unit. I'll be glad to comment on how the both run heat wise once I get the XPR-2. I just ordered the XPR-2 today, but asked that they not ship it out until Thursday as I'm going to be out of town until next weekend. I will say that I've always run my own type of a dual fan exhaust setup, so all of my power amplifiers feel cool to the touch. Though I initially don't use the fans just to see how hot an amplifier will run at normal operation. |

The longest I've left them on for is for a few hours during the holidays. By then the rear of the amp was still about room temperature and the front was slightly warmer. The volume on the XDA-1 varied bt 20 and 35. By comparison I've had Rotel 1090's (bi-amped) in the same setup that you could cook on top of. I've also had a McIntosh MC207 (also bi-amped) that was somewhere between the Rotel and Emotiva. To me these run very cool, again I'm very impressed with these amps! I see in your post you stated that you have had "Rotel" and "McIntosh" which by right are really good amps.I would like too know what you think coming from having them two amps and going to an Emotiva amp?Some say Emotivas top end can be brite?I for one don't see EMOs amp like that at all.What do you think? I agree, I can't say that I find the XPR's color the sound in any way (to me). I've read several times that Emotiva builds good amps for the price, based on my limited experince I think the XPR-1's are great period. |

Regarding xpr-2 running hot. I have xpr2 running two front paradigm 100 and, xpr3 running paradigm 670 center and two rear paradigm 100. Purchased xpr2 spring 2012 and has always run very warm, whereas the xpr3 cool. I can leave my hand on top of xpr2 without removing so cannot say it is hot but definately gives off some heat. Both amps connected to Denon 4806.
odd thing with xpr2 is that only the left side (facing amp) runs very warm while right side stays cool? All led indicators seem fine and have not clipped/shutdown. I have sent email to support and waiting response

I think you also meant "XPA-2", right? Because the XPR-2 has only very recently become available... |

I have both the XPR-5 and a set of XPR-1's. After running the XPR-1's for a few hours they run warm. They are driving a set of Mirage M1's. I find that the XPR-5 runs very cool in comparison and it is also driving large speakers (4 Mirage M3's)

I've turned the volume up as far as I dare go, hoping I don't blow up my speakers in the process and still can't even get a flicker. Hopefully I'll hear from Emo support tomorrow. I know this is a minor thing, but you know how it goes, you want everthing working properly out of the box. Especially their reference line. aud, Wondering what you heard back from support. I rec'd a pair of XPR-1 today and the meters on one work, but not on the other. I can easily get 2 or 3 lights jumping on the one, so it's not a matter of button pushing. Waiting for a callback from the tech support folks when they get back from lunch. update: the guys called me back a few times (very promptly) and after an internal discussion with Lonnie they want to swap out the one whose lights don't dance. Since the meters on one of mine move easily and the other doesn't, they know it's not an issue of sensitive speakers, etc. It's probably something like a ribbon cable issue spoiling communication with the front panel, etc. No big deal since they'll handle swapping out the monster. I probably need the exercise anyway. further update: while testing earlier, I had cycled through all of the meter settings as well as gone into standby and back with no effect on the meters working, but after my discussion with tech support I wanted to make extra sure and completely power off (switch on the back) and try again and the meters are working on that one now. When you power these on (switch), there are 3 delayed clicks where they are doing internal checks before they go to standby, so must have been an issue there that the subsequent checks when you come off standby can't clear. So, good news - gotta call the guys back. |

I have been running my XPR-2 for about 4 hours this morning, driving it with an XSP-1 at about -45 on the volume selector (ie not very loud!).
Also, only the bottom channel power LED's on the XPR-2 are lit, so not a lot of volume being pushed thru.
I just went over and touched the top of the XPR-2. Yes it is quite warm, bordering on hot. I am, however, able to keep my hand on the top without having to remove it.
I would assume this is pretty much normal.

I have always found Emotiva's power amplifiers to be neutral, meaning the signal in is what you get, signal out, or no coloration of it. I know many enthusiasts like to use descriptive terms such as warm and bright, but IMO the source, speakers and room treatments are what mainly effect what we all describe as what we are hearing. Shouldn't a power amplifier only do what it's supposed to do, which is amplify the signal being fed without coloring it? Yes you are correct my good mod. Those other folks are "hearing things."  |

So, good news - gotta call the guys back. Hi thorcorps, I wish I had your kind of luck. I've done everything above and about six other things repeatedly to no avail before I called support. I was lucky to get Lonnie who is very good to work with. He's baffled that both of my XPR-1s have the same meter problem. He told me he wanted to run some tests in the lab and he would call me back. That was yesterday. I'll keep you posted if you want me to and if he calls me back. I'm hopefull he will. I'm very happy to hear you got yours working.  I would appreciate your opinion of how they sound to you, with your good recordings that you know well. Take your time. I'm starting to realize they require at least 20 hours of burn in and then I got serious with some critical listening. So far it just keeps getting better. |

not to go off track, but would the amplifiers work if the LED meters were disconnected all together, other than cosmetics i don't find them too useful.

After about 5 hours of them playing yesterday I noticed some pretty drastic changes had occured (for the better), then a few hours later I noticed some additional things. I expect I can get plenty of hours on them this weekend, then I should be ready to start sharing opinions. They were definitely starting to impress me last night. |

Yep, you have almost every available option with regard to the display, at least on the XPR-1s. Meters going up, meters left to right, meters right to left, no meters, accent lighting off, 5 levels of dimming for meters and accent lighting, no meters or accent lighting - just the little blue light showing that it's on (versus red for standby), etc.

Meters just monitor the amps outputs with no affect on the output signal. I keep them off. I can't get them to show any signal on the display anyway. |

I also own 2 XPR-1's which power a pair of Focal Grande Utopia Em speakers. What I notice about the indicators of the XPR's is that they do not behave consistently. I think the indicators are too sensitive, as sometimes they go up 2-3 levels even at a complete silence (pre-amp switched off) and the left behaves differently than the right.
And yes, the amps need some burn in. Their sound got much better after few days of usage (or I am getting accustomed). Whatever it is, I like them.
The amps run warm, but not hot. Quite normal behavior for class AB amplifiers. Probably XPR-2 runs warm too. This is not a defect.
So far, excluding the indicators inconsistence my amps work fine.

So I took delivery of my XPR-2 a couple of weeks ago along with an XPR-5. The XPR-5 runs almost stone cold - just like the Sunfire 7x400 did before it. The XPR-2 is hot enough to make me worried. After it had been on for a few hours yesterday it was almost too hot to touch.
As this is also a class A/B & H I'd expected it to be cool too. Then I started watching the power draw from my Furman power conditioner. The XPR-5 will power up and with no signal settle down to about 0.8 Amps. The XPR-2 initially will draw about the same. But then still with no signal the power draw ramps up over about 5 minutes to over 3.5 amps. I've even repeated the process with all the inputs and speakers removed from the XPR-2. Same behavior. Current draw ramps up over 5 minutes to just over 3.5 amps. That's over 400 watts going to heat.
Anyone any ideas?

I've monitored the usage of my XPR-5 while idle over night - and it's consistent with yours. Somewhere around 85 watts or something. The ramp up of the XPR-2 while idle doesn't sound normal. That's an awful lot of heat to dissapate while idle! A call to support is probably in order... |

My xpr 2 idles at about 3.4 -3.8 amps and runs the same temperature whether I'm pushing it or it is idling.
everyone who owns an xpr 2 says it runs hot especially in comparison to the xpr 5.
