I still think it would be nice if this was explained in the item description, in the FAQ or at least in the manual. I can think of a number of circumstances where this info could be useful to a buyer deciding between different amp configurations, and not every potential buyer is going to stubble across this tread on the forum. A warning in the manual would also be nice, something like "this amplifier is more prone to damage when less channels are in use, use common sense when driving one or two channels at high levels" That`s just common sens don`t you think? I`m sorry and I do not me this in a offensive way , but I have some brain damage do to an accident and I no not to over drive an amp or use it in a way that it was not designed , It would take 20 pages or more for them to try to explain all the ways on how one could abuse an amp or miss use it , you truly can`t expect Emotiva to take responsibility to teach every prospective buyer on how to use an amp the buyer has to take some responsibility on knowing what there buying and how to use it that`s why they have support and contact us on there web site . No offense taken, and I suppose your right... I don't doubt that almost everyone knows you can damage an amp by over driving it, but Its news to me that it is more of an issue when using less channels. I guess the bottom line is, most people will never push their amps hard enough to do damage, and Emotiva amps are as robust as any other in this regard.

On regards of not using all channels , if not in use periodically then no there is nothing wrong with doing that but if say your not going to use them for year or more then yes because electronics are made to be used ,I have put perfectly working amps away because of my job only to came back a year later and they would not work a resistor or rectifier went bad so I then started leaving it with family to use and it never went bad when I did that so I know from experience leaving audio gear unused for extended periods can make them fail and even in my onkyo pre/pro manual it says not to leave it unused for extended periods or it may fail so anyway that`s my experience and thought on the matter

Maybe it depends where they are stored, if left unused there is more chance of condensation/damp/mould which might corrode connections etc I would think?

No I had it stored in a controlled room and I have had tech`s tell me that like anything that`s meant to be run can fail if left idol for to long like parts in engines can dry rot for example ,all I no is I was told I should run electricity through them periodically to keep them in good operating condition

hey all, was thinking of selling my XPA5 and buying a UPA5 cause of the deal they are having. would i notice a huge difference in headroom? i live in a townhouse now and dont crank it like i use too.
i would be putting a bit over $200 back in the bank if i did this move. i have a potential buyer already.
any thoughts??

I listen to my Magnepan IIIas in two channel quite a bit with my XPA-5. I know there is a previous thread that stated if you play your XPA-5 extremely loud in two channel for an extended period of time do you run the risk of damaging the XPA-5. This is probably the only time you possibly can stress the XPA-5. But from my experience, it would stress me before the amp. I have owned my XPA-5 for more than a year without any problems running a Magnepan home theater system in two channel or five channel. Listen to the real world users. You know, this thinking could apply to any multi-channel amp by any manufacturer. I used to own a Parasound HCA-1205A, a five-channel amp to power my Magnepans and never had a problem with two-channel listening. But then again, I never listened at ear-bleeding levels that Emotiva suggests to avoid with the XPA-5 for an extended two-channel experience. Any way to put this at rest? This has been asked many times and it looks like it is not a problem at all.

Like I said I don`t think it really matters if you do it from time to time it`s if you leave it idol/off for a year or more at least that`s when I had problems

Is it a bad idea to run my new 9-channel amplifiers A/V Receiver in only 5.1?

Is it a bad idea to run my new 9-channel amplifiers A/V Receiver in only 5.1? Why would you buy a 9 channel AVR if you're only going to use 5 of them? I would think if you're preparing for the future to add the other channels, unless that is going to be pretty soon, by the time that rolls around something else will have come out that you wish you bought instead. ;D

I would think if you're preparing for the future to add the other channels, unless that is going to be pretty soon, by the time that rolls around something else will have come out that you wish you bought instead. ;D It was a double jeopardy question. * Several people have a 9-channel (internal power amps) receiver, but they only use five or seven of them. Their rooms simply won't allow them to add those extra speakers. But they wanted to have the latest features and technologies (Audyssey MultEQ XT32 and preamp mode for example), so they went for it! And in some cases (like with the Denon AVR-4311CI A/V Receiver for example), some people don't even use any of the internal amps, but add external amps. So they end up with 9 internal passive power amps from their receiver! >>> My point was to simply state that there are no rules as to how many power amp channels you use in a multichannel amplifier or A/V receiver. It just don't matter a single bit. * Case in point: the UPA-5 right now only cost $25 more (with free shipping) than the UPA-2. So why not buy the UPA-5 then? ...More use can be squeeze from it (future upgrading on more speakers, or bi-amping, or powering a passive subwoofer for example, plus...). This is a no-brainer choice. => It's like why carrying a condom to the secluded wilderness and extreme cold of the North Pole? Well, better have one than needing one, right?

Can't argue with that! ;D Yeah, there's all these posts from people worried about the effect of not using all the channels on their Emo amp but when you think of it, a bunch of the 7 channel (and now 9 and 11 and who knows what else) only are using 5 speakers so those other channels are not being used there either but no one worries about that.

Yes if you never plan to use them then who cares if those channels fail and who would even no they did and are they really idol/off when not in use in that way I guess I wasn`t being very clear sorry I do that a lot I was talking about amps that are never turned on for a year or more then yes they can fail I`ve experienced it time and time again periodically using them on and off no problem it`s the extended down time that you “could” see failure of channels it all depends on how long you leave them off and I`ve even seen it in manuals stating (Not to leave them off for to long ) even in pre/pro manuals I`ve seen this , if you happen to have an onkyo pre/pro look in the manual it will state that if left unused for extended periods it may fail and to turn it on from time to time

If Emotiva has another Christmas sale and with the strong Aussie Dollar (I'm from Australia) i'm thinking of pickup an XPA-2 for future use - these 2 factors alone will result in a significant saving for me. The amp will sit dormant and unopened for 12 months before I have a proper setup.
Is it ok to leave the amp unpacked for that long ? or am I being stupid and should only buy the amp when required ? even if I do wait, whats to say that in 12 months time I dont end up receiving an amp thats been sitting on the warehouse shelves for 12 months (in theory anyway, but in reality i'm sure Emotiva will turnover their stock quite quickly).

If you have a problem, within 5 years of purchase, they will send out parts to you (I had an XPA-5 board sent). So if you store it well I think you only risk a year of warranty. You can always open it up, power it up and let it run for a few hours every couple of months if you are worried about it. Maybe do it on cold days so you are not wasting electricity.

I was just saying what my experience has been in the past and what I`ve read in manuals , I`m suer you will be OK but I would open it as soon as you get it to make suer no damage incurred during shipping and it turns on ok before packing it away and or call Emo and ask there thoughts on long term storage
