BTW, are my eyes deceiving me or is the XPR-2 fully balanced as well?! |

Among Emotiva's amplifiers, only the XPA-1 and XPR-1 are fully balanced. I'd like to know if these run at class A until a low wattage threshold.

They might be deceiving you. It doesn't say fully balanced.

Schitt!!

On the xpr-2 page it says "It incorporates refined, discrete quad-balanced input circuit topologies with fully complementary high bandwidth power stage design, "
Though it doesn't add the words differential power amplifier like it does for the xpr-1. Hmmmm.....
Now unlike the other not fully balanced amps which mention dual differential this is quad balanced like the xpa-1.
Maybe somebody can enlighten us to the difference.

Wow.... those are beautiful amps...  Now for the XPA-1L!  |

Hmmmm..... Now unlike the other not fully balanced amps which mention dual differential this is quad balanced like the xpa-1. Maybe somebody can enlighten us to the difference. True, it does say this. However, under FEATURES, it says this: Fully discrete, dual differential, cross coupled input design with four active current sources.If the XPR-2 is indeed fully balanced (e.g. Differential Reference), then huge props to Emotiva. However, I'm more inclined to think it's just a typo. EDIT: Here's the text under FEATURES for the XPR-1 for comparison: Fully balanced, fully discrete, quad Differential Reference™ circuit design.In any case, I have no doubt these are fantastic amplifiers based on the very positive feedback from the XPR-5. I am hoping these new Reference series products will be compared to the super-expensive big boys for power and performance. Emotiva has hit the ball out of the park in my opinion. Well done!! ;D Now I must close my browser window, walk away, and find some constructive way to deal with the incredible lust I now feel towards these amplifiers.  |

These look amazing, I don't need amps in the slightest (well, an XPA-7), but now I want a pair of XPR-1's. At this price it's going to be hard to resist. Maybe another typo? In the first paragraph for the XPR-1 it says: "Packed inside this massive 95 pound, rock-solid, jewel-finished chassis, resides decades of design expertise and hundreds of man-hours of fine-tuning." Then at the bottom of the page: "Weight: 81.4 lbs (net)" |

Dam them for releasing these right before Christmas. I really dont need. I want real bad. I need to cut up the credit card before I accidently drop it and buy these..... noooooooo...(in darth vader voice)

I think that they are saying that the xpr-2 has differential input stages that actually use both signal and inverted signal. But that the amplification stage is single ended.
The xPR-1 would then be fully balanced because in some ways you could think of it as a bridged xpr-2. Ie instead of left and right you have signal and its inverted pair.

I'm dying over here. Was at the holiday party for work (many drinks in) when my buddy texted me and said "did you see the amps yet?" I knew that meant Emo put the XPR-1 & 2 out there. But I haven't had a chance to sit down and really look at them. I will today. It's just hard to get excited looking at big monoblocks on a small phone. :-)
But gentlemen...this is what we have been waiting for.
Anyone ordered yet?

Should this be moved into the Amplifier Forum instead of amplifier FAQs?
Totally missed this thread till now!

Then at the bottom of the page: "Weight: 81.4 lbs (net)" It looks like they fixed the typo. Now says "massive 82 pound"... |

Fully discrete, dual differential, cross coupled input design with four active current sources. I believe that it needs to be *quad* differential to be fully balanced. The XPA-2/3/5 are dual differential just like the XPR-2, and they're not fully balanced. Edit: OK............ I now see the "quad" references in the XPR-2 page... Clear as mud!! I emailed sales to ask: Features Fully discrete, dual differential, cross coupled input design with four active current sources. Topology: Fully discrete, quad differential, 2nd paragraph: "It incorporates refined, discrete quad-balanced input circuit topologies" |

Well folks, talk is cheap. All of you are drooling over these amps, and rightly so, but WHO HAS ACTUALLY CLICKED THE BUY BUTTON? Hmmm?  |

Hehehe...I need to make sure they fit when i get home tonight. I have to pull my old audio rack out and reassemble.

Jimbo, its all that added cost though...new rack, new electric...aww hell...I'll probably be putting three in the cart tonight. Who am I kidding? |

What I like about the XPR-1 monoblocks is that at this sale price you get 4000 watts of power at 4 ohms, fully balanced, and 580,000 mf of capacitance for 2.6 K. Most higher end amps start their beginning offerings at that price and don't offer that kind of power so it is really good value. Plus you could get an xda-2 and be out of the door for less than 3 grand and have all the source you need for a good quality stereo setup. Add in an xsp-1 and it becomes really something special. It's obvious there's been a lot of thought put behind all this. They are offerring a full line up of models from emotiva in a way that satisfies a niche with nearly every product and yet offers a complete package. Once their new speakers come out, I think the audio world will have no choice but to seriously consider their products. I'm really surprised it's not more well known.
