Looks like you can forget 4 ohms loads because they're bridged modules. May I ask, without getting pummeled, do they have linear/toroidal power supplies? Unless I'm mistaken these are the double wide modules they were talking about. They required a new power supply for balanced operation. But there was no mention of a torroid. However I don't see a reason that these aren't optimized for lower impedances like the XPA-1. Keith mentioned they were called monoblock modules because they were optimized for bridged operation. I assume that means they can handle lower impedance loads. |

ALL MODELS: Power Output Per Channel
300 watts RMS per channel; 20 Hz – 20 kHz; THD < 0.1%; into 8 Ohms
550 watts RMS per channel; 20 Hz – 20 kHz; THD < 0.2%; into 4 Ohms
800 watts RMS per channel; 20 Hz – 20 kHz; THD < 0.5%; into 2 Ohms |

Okay, so just how does the XPA-DR-1 differ from the XPA-1 Gen 2, which is also advertised as a "DIFFERENTIAL REFERENCE CLASS A/AB MONOBLOCK POWER AMPLIFIER", , described as "fully balanced, fully discrete, quad differential, ultra high current, short signal path selectable Class A/AB," and spec'ed at 1,000 watts RMS @ 4 ohms and 600 watts RMS @ 8 ohms/ Are they the same product with different names and cosmetic properties, or are they really different from each other? Amyone? I'm gathering these are the gen 3 XPA-1 double wide blades they were talking about. I think they wisely changed the naming from "monoblock modules" to differential reference modules. Because that is closer to what they are and a good solid name imo. Though the power supply is different - due to the needs of balanced drive, these are not gen 2 amps. So I'm assuming what we don't get is the 1.2 kva torroid transformer, the 180,000 mf of capacitance, or the 60 watts class A. Though we do still get the ton of power and the balanced drive. Emotiva has never made a fully balanced multichannel amp before. So this bit is new. I'm not seeing this as an upgrade to my XPA-1 gen 2. I could see a home theater enthusiast liking this kind of balanced multichannel amp for their LCR. Or somebody wanting to jump in to lighter weight monoblocks |

sahmen garbulkyLook at the Emofest pix...3rd post down in link below. The picture of the balanced mono module certainly is what it looks like is inside the pix above. So, even without a podcast for novisnick, I think it's a safe bet that the pix above are the dual-blade modules so many have been waiting for. I think it's also safe to assume they have the switching power supply, just the special one needed for these modules as that is what they have been talking all along. --->LOOK AT THE PICTURE, 3rd post down in this linkey-poo<----Mark

^^^ I’d agree, SMPS+, configurable blades (up to 3), the blade design, and the slotted chassis (ala the G3) would be the major differences from the XPA-1 G2.

It's the end of the XPA-1 as we know it

Fully Balanced Fully Differential and ready to go at a price no one else can touch. DR can also stand for the DR.Emotiva is in and ready to cure your Differentially Balanced Amplifier desires. This is the perscription to your Music and Movie enjoyment. Crazy good and can't wait to hear them!

The XPA-1 G2 will continue as long as there is market demand. It’s a classic.
The new XPA DR’s are extremely good, and VERY quiet. We’re totally committed to the big SMPS design moving forward. They offer so many advantages over old iron, it’s hard to go back! And speaking of your back... half the weight!!
We think you’ll love these new models.

Looks like the XPA-1 Gen2 is still the kingpin!

That’s what I meant by “blade design”, I’d probably say they blended the two lines into this product. |

Sure, but I was referring more to the amp circuitry on the blade. ie. the XPA tech was on the XPA-5 blades. This is XPR tech on blades. Both are blades but different amp design.
Although to your point the XPA blades in the XPA-3/5/7 don't appear to be sonically as good as the XPA non-blades in the XPA-1 or 2.

To confuse things more the XPR blades are derived from XPA blades. |

A couple of quick spec's... XPA DR-1 Power Output 600 watts RMS 8 ohms, less than .01%
1,000 watts RMS 4 ohms, less than .05%
1,500 watts RMS 2 ohms, less than .075%Not bad for a little over a grand... :  |

But how do they sound compared to the XPA-1 Gen 2? Better worse or just different.

See now I want to see the specs on a DR 3 at 4 ohms all channels driven......XPRs could be on the chopping block(actually I will keep two for a nice two-channel system  ) |
