In Emotiva's own manual, they reference the 8ohm output at both 250w and 300w just pages apart.
Most reviews I've ever read including Audioholics call it 250w. Customer service looked at the Audio Precision spec data and confirmed it is 300w and chalked up the reviews and manual as a typo.
Also mentioned in the Audioholics piece were some other possibly misquoted / typo specs.
I'm new here (having just purchased a gen 2!) so maybe this has been discussed before. I'm just the curious type, so I'm wondering if there was ever some confirmation about why such an important product to their line seemed to get some relatively simple details of whack in print. Any ideas?
Thanks! I've already learned a lot reading this forum and I'm excited to receive my first piece of Emotiva for my kit!

I've almost never seen a manual for a technical piece of equipment that did not have some errors. I think it stems from the semi-technical people that constitute most of technical writers as the original engineers have more important things to mind.

If it was just the manual I wouldn't think much about it.
But in the Audioholics review, for example, it seemed like the author and Dan were somewhat acquainted with each other. I seems like a simple correction Dan would want to take a second to correct in what amounts to a fairly high profile, glowing review for Emotiva. In fact I think EVERY review I've found calls it 250wpc. Surly Emo would have tried to correct this understatement, right? Unless they were originally calling it 250w. In which case why?
I know this is a trivial question for someone who doesn't even own the amp. But it's odd enough to me that it's just become a curiosity.

Fortunately they publish more detailed test data (unfortunately this is just a simple 1 kHz signal, so I suspect things get worse with a real-world signal): emotiva.com/resources/media/xpa2/xpa2_gen2_8ohm.pdf (this is Gen 2). Check out page 7. It seems that distortion starts exploding at around 220 W, but doesn't exceed 0.1% THD+N until a little later – maybe 230 W. By 300 W, the distortion reaches 0.2%, which is probably still inaudible. Some of the more evil mainstream brands publish their power specs with 10% THD+N. |

I believe Big Dan or Lonnie mentioned a couple of years ago that they were very conservative with the ratings of the XPA-2 back then, No its not a mistake/misprint...It's just updated now

Thanks for your reply. I figured there was some decision along the way to revise the specs. No big deal. I would have been more concerned if it truly was just an oversight somehow. That seemed impossible, so I had to ask. Cheers! |

I have two xpa-2 gen 1 and they are in bridged mode where each one drives a B&W 802. I rarely get above 3 LED's and there is headroom no doubt about it.

Both ratings are correct. It is a true 300 watt amp. But it simply does it with a slightly less conservative rating.

So you guys think I should buy these amps, I really wanted a 300 watts not 250 watts for xpa 2
But if you guys are saying the 1st gen xpa-2 is 300 than I should go for it, he purchased these units in June 2010 so I still have the warranty for it. Any suggest suggestions
I have rti a9 for the front.

I had an XPA-2 Gen 1 and it was definitely 300 watts into 8 ohms and 500 watts into 4 ohms.
Cheers

I've got the 1st Gen XPA-2 as well driving my set of Polk Audio LSIM 705s that are rated up to 250 watts. I've heard plenty of people mention that these speakers love watts and perform great well over 250 watts. I've cranked mine quite a few times to ear ringing volumes. The amp no doubt keeps them fed!  |

I have the XPA-2 1st Gen, driving LSi-15's 4ohms load, and the 8" woofer isn't the best in it, was driving them with my UPA-1 monoblocks and can say when I put the XPA-2 on them
they really came alive not that the UPA-1's didn't do a good job of it they did, just a lot better when cranked up something to be said about a bigger power supply and a lot more
output at the rail. I really luv them amps they will be in my system for as long as I can keep them going best deal I ever made on some really good amps.

The XPA-2 is a really good amp. You may not realize it but 50 extra watts gives you very little appreciable increase in volume. For instance 250 watts to 300 watts does not give you a 20% increase in the volume that you percieve. And 500 watts does not give you a 100% increase in volume because of the way volume is percieved by the ears. It's much lower than that. So if your decision was based on fifty watts then I think you may not realize what a small difference that makes. Also if I am gathering the price you gave was for both the XPA-2 and the XPA-5, and no shipping required then yes it is a good price. The XPA-5 and XPA-2 are heavy so if shipping is involved you have to factor that into the price.

I would trust the guys on this forum. If they say it's 300 I'd say it's a pretty good bet they are .
As Mr. Garbulky stated about watts verus decibel ..50 watts isn't going to make a world of difference..There is a calculation and hopefully someone else with more
knowledge will jump in.. I have the rtia9's up front with a PA-7 (350 watts a channel ) ..I love the extra headroom...The Rtia9's are rated 50-500 so they do like
wattage..You can't go wrong with Emotiva amps..
