dingdong. You are missing a few things. The XPA-1 gen 2 has not been reviewed yet and uses a different gain struture - 29 db vs the XPA-1 gen 1 which is 32db. The gen 2 is still waiting for release. The XPR-1 takes 3.5 V to be driven to full but it has twice the power so at 3.5 V you are driving TWICE the power. So for the same amount of power output, the differences may not be as massive as you might think. I.e. at your listening volume you may be using 0.3 V with the XPR-1 and 0.4 V with the XPA-1 (as a hypotethical). Third. You really can't base your conclusions on the sound of an amplifier by small differences like gain structure. They are nice guides but experience has told me there's a whole lot more to it. So guessing these things is nearly impossible to be accurate. If I were you and I'm not, I would get the XPA-1 gen 2. I like the idea of class A and 60 watts of class A gives you 120 watts of Class A in stereo - and that's a LOT. I'm not convinced that sound is all about headroom. Don't get me wrong, it certainly plays a part but it's not all what it's about. I did a head to head with a mini-x (50 watts), an XPA-2 (300 watts) and a NAD amp (30 watts) in a reasonably unfamiliar environment. Well guess what the NAD amp didn't fall on its face at all, it sounded great and warmer than the others. I couldn't distinguish the mini-x from the XPA-2 (!) Yeah I know. I was surprised. I was epecting an absolute wipe out. But it wasn't - not even with just 30 watts of power. But later, I was able to distinguish the UPA-2 from the XPA-2 when I had it in my system. The XPA-2 was quicker. I ended up preferring the soundstage of the UPA-2 but really liked the quickness of the XPA-2 - it was a preference thing. Hello, Thank you very much for sharing your thoughts. You are absolutely right about basing the decision on small differences in gain structure. However, I've got to use what's at hand, as these are to heavy to ever be returned from Europe due to high freight cost. Luckily, Emotiva is willing to do an extended QC before the amps are shipped here, so at least I know they are 100 % working before they are shipped. If I were in the US and could take advantage of their return policy, I would try them in a heartbeat without doing all this research. I wish Emotiva opened up a European distribution center. Also, thank you for extending my knowledge with respect to how the gain levels work on the two monos, as I did not take this into consideration. You are correct that I had missed the launch of gen 2, good thing you told me so I didn't place an order for XPA-1 gen 1, as I was under the impression that those gave 60wpc class A. Do you or anybody else know when XPA-1 gen 2 will be launched? Have been searching the forums and it seems like the news broke in August this year. Xmas is coming up, and one would think they would be launched before that? Also does anyone know how often Emotiva has sales with reduced prices? Even though they are cheap compared to their competitors, one got to save whenever possible.  Reading everything here, I'm more and more inclined to go for XPA-1 gen 2. |

I think you would be in the 60 watts most of the time in Class A unless you want bleeding ears =/ And its going to be good for long XLR cable runs in installations since it's fully balanced assuming your preamp is fully balanced as well. Assuming it stays similar to XPA-1 GEN 1 It stays in class A/B all the way to 500 watts vs 340. www.jblpro.com/pub/obsolete/443035.pdfThe continuous program power is 300 W. With a peak of 2kW with a sensitivity of 93 at 1 watt @ 1M At 50 watts 110db SPL on axis @ 1M ==================================== 2nd harmonic - low med and High - Equal to or below 3% / 0.6% / 6% 3rd harmonic - low med and High - Equal to or below 1% / 1% / 1% 110 db is quite loud equivalent to a power saw at 3' the XPA-1 can do another 450. Pushing the volume might cause distortion you don't like. But then I do not own those speakers. 115 db is equivalent to a loud concert those speakers can do 119 db continuous which is the max. Most likely 300 watts program. I therefore conclude XPA-1 GEN2 once it exists is all you need...it can take 2 ohm dips too (apparently up to 1,750 watts I read from somewhere on this forum) So I'm with Bootman on this one... Errr... yeah I think I got everything right.  Although having 240,000uf on one channel, 480,0000uF on both would be fun. Not sure if your ready to get 2x 20A lines and increase your cost. As stated in the Specifications "The XPR-1 requires a 20 Amp circuit and standard IEC 20 Amp outlet (which is different than a 15 Amp outlet). If you don’t have a proper circuit and outlet. We recommend you have one installed by a qualified electrician. We recommend that the XPR-1 be plugged into its own dedicated 20 Amp circuit." Your extra $$ can go to CD or a processors win win Thanks for your input, it's very welcomed and appreciated! In Europe, at least where I live (Norway), 220-240V @ 16Amps are common (and I have a dedicated one in this room), so there is no need for a 20A circuit or special outlet, as (best case) gives 240V x 16A = 3840W, which should be enough for a pair of XPR-1's, even at drops in impedance. We're lucky that way. Obviously, I will not listen to these speakers at ear bleeding levels all the time, but having the option to do it occasionally doesn't hurt, hehehe. However, as the 60wpc class A will be enough in most cases, I have to admit that there is a bias towards the XPA-1 gen 2's right now. I'm just afraid I'll regret not getting the extra powah, you know, like lying awake at night thinking "what if?" lol... |

They are working on the website and stocking the warehouse. |

^ Wow this is great news! Did they say anything about the location, and did they have a date on when the doors would open? This is great news for European customers given Emotiva's 5 year warranty!

Wow, lots of great news in that podcast. More importantly, 1) Distribution center in Europe ready to ship within 30-45 days from the making of the podcast, which was October 2nd. 2) Warranty will be handled in Europe as well as the US. 3) Last holiday sale starting October 15th I wonder if they launch XPA-1 gen 2 during the holiday sale! I'll gladly wait for them to ship it from the European distribution center! Wooohooo! Now that a European facility is in the making shipping will be less expensive, I'm thinking 2 x XPA-1 and 2 x XPA-1L for active crossover. Using XPA-1L for the horns and XPA-1 gen 2 for the 15"! Mama mia! |

For all of you who may or may not be wondering about the decision.
I'm going to wait for and buy a pair of XPA-1 generation 2 when they are launched, possibly with an additional pair of XPA-1L's for the horns in an active crossover setup for the JBL 4430's. This will yield 35w class A power for the horns and 60w class A for the woofers. I think this will be a very good setup, with more than enough power as the power requirement will go down when the passive crossover in the loudspeakers are bypassed.

That will be a nice stack of amplifiers, won't need much of a heater in winter hehe

Threas starter here. A couple of days ago the XPR-1's turned up in the Norwegian classifieds and I just couldn't resist. Look at this!! Woohooo!!! ;D  I need to reinforce the stereo furniture to hold these heavy monsters so I'll have some dancing space in the front! LOL! |

And another thing that has to be said about the XPR series is that they look far better in person than on the images that you see in the Emotiva web shop. Thanks to all of you who helped me in this thread, I think these amps are the end game In no way am I emptying these things of power and they sound spectacular both when played loud and fairly low. Good dynamics and hard hitting bass! |

Help, I'm sweating like a pig and my ears bleed! LOL!  I'm doing active crossover on a pair of JBL 4343B here now, and woohoo! Fun times! Glad it is winter though, because these XPR-1's sure heats the room and then some Still have the 4430's, and I was maybe thinking of using them as rear speakers or something, haha. These 4343B's need some restoration, also they make everything look unproportionately small. Not regretting getting the XPR-1's, they're a blast - literally! |

dingdong,
Welcome to the club. XPR-1s are the most expensive space heaters I've ever owned! I wouldn't trade them,,,,,That's for sure.
FS: oil filled space heater, recently retired,,,,,,,,,,..
Peace,
Nick
ENJOY THE BIG DOGS

I had that exact setup and it was wonderful most times. But because of the CD horn, I found music rolled off too much for my taste, so I had to offset with treble boosting equalizers or even the software on the computer if playing from hard disc. If you are not having roll off problems, the sound was world class, XPR-2, Generation 1(!) and 4430, and I used a Samson outdoor EQ, without the CD horn correction set.

Also, btw, someone might have done something to mine; they weighed about 110 pounds each.
