Well I have an xpr2 and an xpr5. I received my xpr5 as the xpr2 was out of stock when I ordered. I hooked up the xpr5 first and that amp ran as cool as can be. I was actually suprised at how cool it was running. Fast forward, I received my XPR2 on tuesday. I hooked it up and have pushed it moderately but not to hard and that amp gives off some decent heat. the case is very warm to the touch. Is this normal? I am running Monitor Audio GX300's. I read that the xpr series runs pretty cool but mine xpr2 doesn't Thanks

How are you liking your new XPR-2? and what AVR or Pre-Amp are you using with it?I am thinking of getting that same amp for my two channel set up.You said it is running a lil hot?is it in a cabinet? if so try using a fan too help cool it.

I have two XPR-1s. They run warm to hot. Nothing that seems out of the norm, based on my 30 some years of experimenting with a number of different amps. Remember these babies can produce alot of raw power. I have had amplifers you could fry an egg on. Not to change the subject, but I wanted to ask if your LED meters are working. Mine haven't worked out of the box. I've emailed support 4 days ago but haven't received a response yet.

I've also got two XPR-1's and they run very cool, actually very impressed by this. The one time I needed customer support they were very quick and helpful, I'm sure they can tell you if your XPR-2 is operating normally.
Good luck!

Be interesting to know the current draw at idle between the units that run hot and those that run cool; also the rack and ventilation. Many in the past have commented on how cool the XPR-5 runs so you'd expect the other XPRs to be the same.

Hi moonguy, when you place your hand on the top of your amps towards the back of the transformers, they don't even feel warm after running for an hour or so? That would be impressive.

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!

Thanks, moonguy. It sounds like we're in the same temp range. Since I've had a few days to burn them in, they're starting to sound tremendous. Just wish I would hear from support about the LED meter bar graphs not working on both the XPR's.

Just to ask what may be obvious, did you check to be sure the meter is turned on from the front panel switch? If you have efficient speakers and do not listen very loud the meter will not come on. In my biamped system the XPR-2 is used for midrange and up duty and I have only seen the meter flicker once - and this is with inefficient speakers.

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 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? |

Are you capable of checking the bias settings for the transistors and/or channel?
Sounds like the bias setting is high.
Talk to Lonnie.

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

Hey willcycle, thanks for asking. I've been hoping that its just something I'm missing, but now I think it's in the ARM 7 processors and the way they were programmed and/or calibrated at the factory. I'm so glad you gave me your hook up and operation scenario. I've pushed the front buttons with so many different combinations I've lost count. I have the XPR-1's hooked up full range and bi-wired to my Paradigm Studio 100's ver.4. No bi-amping. 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.

I am loving the xpr series. I came from bryston and classe amps. Definitely enjoying them. |

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. |
