I can't find any minimum distance around the XPA5 needed for cooling in the owner's manual, other than the standard clause given in page 3.
Just from my personal experience, 1" is not enough unless you are using fans in your cabinet. I have about 3.5" in my cabinet with no fans, and I have never had a problem with heat in the least. I would note, that in the section of my cabinet where my Emotiva is located, I do not have any other A/V equipment located there.

Picking up my first amp tomorrow. XPA-3 gen 1


Buying just to see if it makes a difference, play around.


My AVR puts out 125wpc, I have high eff Klipsch speakers.


I heard it will make no difference with my AVR power and speakers.


Any recommendations?


What is the year difference in gen 1 and gen 2, and what are the differences. Any problems I might encounter.


Thanks in advance

If your Klipsch is very efficient, like over 100db, addl. amp. won't make as much difference(power handling wise) as on a 85db speaker.

OH DEAR LOL 27W a channel???

"I heard it will make no difference with my AVR power and speakers."

27W is pretty poor, so your Emotiva will be upgrade. Actually Klipsch have been found to be less efficient than stated specifications.

Jealous of my speakers?

Wow that is poor for HK's highest offering AVR. I only run a 5.1 with occasional zone 2. If I run the front stage off the amp it would leave the 125wpc to run surrounds correct?


I tried finding a bench test for my old HK 354 and couldn't, any chance you could link one. I just want to see the two compared as the 354 with much lower rating, seemed to perform well. Thanks for the bench test link, it is valuable info that I probably should have looked at by now or before purchasing. Although I am happy with it overall

yup. Basically it's ok for 2 channels. So if you buy a amp for sides, rears, and center then you can use the HK for L/R. Although you could just use the rears (2 channels) so a 5 channel for L/C/R and sides. I'd do that.

I'm getting the XPA3, would I be better off running the FL/C/FR off the amp and let the hk do the surrounds? Not sure why I would have the higher watts split between front and back. Or does it really not matter how it is configured?

I'd guess, the way it feels that a good 3-4" would not a no worry situation. Ive got about 5-6 in mine and it barely gets warm. 1" may be pushing it without a fan. Not saying it would shut off, but the less heat the better.

Note the 27 W/ch test for the HK is all channels driven, which rarely if ever happens in the real world.

I had about 1" clearance over my XPA-3 (since changed to an XPA-5) and it ran pretty warm. I moved a shelf up to give it about 5" ~ 6" and it is fine. My anecdotal experience tells me 1" is not enough clearance but my gut says 3" ~ 4" is probably fine unless you are running it hard.

Note heat will shorten the life of electronics so I agree the cooler the better.

Use the XPA3 for the front three. No it won't matter for power mismatch

Really excited. I just ordered an XPA-5 as part of a complete HT overhaul. For the time being, it will be mated with a Sony STR-DA5300ES AVR, and driving 3x Definitive Technology RCS-II and 2x RSS-III (which are also new and haven't been installed), and an SVS SB-2000 dangling off the AVR. The new TV is being delivered Thursday, and installation will probably commence sometime next week. If everything I've read is true, this Emotive unit will kick some ass, especially in the price-to-value category!

I've noticed that the XPA-7 amp seems to not be getting any love. Over the years there's been a fair amount of clamouring for a 7 channel XPA amp, but perhaps the price tag is a little high?

I have a xpa-5 driving a similar setup with uiw rss speakers for the rears and mythos st for the front. You're going to love it. I also have dual pb-2000 subs. All about that bass!

I got a great deal on my xpa-5 almost a year ago. I'm about to pick up a xpa-2 to drive the front and let the xpa-5 handle the center, surrounds, and surround backs. I'd take a xpa-7 just havent seen any around... Im a big fan of being the second owner

I have an XPA-7 running off my Onkyo and pushing 7 Triad Silver LCR's. It is a great amp so far, but I do think it is a little pricey compared to the XPA-5 considering you only get 2 more channels. I am very happy with it though, and don't plan on changing it out any time soon.

I have a question that perhaps was already answered in this thread, however I'll just ask so I don't have to skim through 72 pages. I am getting ready to build my theater and have the Marantz AV7702, dual Emotiva XPA-5 amps to push the SVS Ultra bookshelf setup in a 7.2.2. Is there a start up power sequence that needs to be followed to avoid the dreadful "pop" noise you get when you turn on the amp before the source? I'm thinking to connect the amps to the AV preamp 12v trigger. By doing that, will I avoid that pop and will the amps automatically power on when the AV is powered on?

My XPA3 is on a trigger from the Denon, and it has a slow soft startup. I hear a low hiss right before it comes on line, no pop at all.

Maybe if you started an XPA-7 thread instead of posting in the XPA-5 thread?

Maybe this thread should be re-titled "XPA-x Amplifiers"?

Re-title is a good idea. This is the only XPA thread with traffic when I got ready to by my 3 so I naturally came here.

I run my Yamaha as a pre out to the xpa 5 and use the 12v trigger to turn the xpa on. No pops, hisses, etc. Works fine

I just switched over to an XPA-7 from a combo of XPA-5 and XPA-200 - right now driving 5 Triad silver LCRs and 2 Triad Silver surrounds - the latter of which are soon to be swapped out for two silver LCRs - so I will soon have the same config. Certainly don't expect any issues either with this setup.

Did you all think I should rerun ypao (yamaha) once I move my FL and FR off of my xpa-5 and onto my xpa-2? The wattage is slightly different but i'm not sure if that would be a big enough impact.

Definitely rerun any REQ program when moving speakers, changing speakers or changing amps. The wattage isn't the issue, its the gain differences between the units (if any, but I wouldn't assume they're the same even if similar amps) and can pretty much assume the gain structure will be different between the avr's internal amps and any external amp, as fatbottom mentioned.

thanks everybody. Once I get it setup I'll rerun it. I more excitd to have all of the surrounds and center running off one amp since I did have 2 of the surrounds still on my AVR. I know it won't make that big of a difference acoustically but I feel like I have a slight obsession in things being setup similar when it comes to this stuff.
