I am planning on buying a XPR-5 as soon as it is available.But I have a question. Can it be used with a 15A circuit or is it made to use only with a 20A circuit? Does it come with a power cord made for 15A outlet or a 20A outlet? Some high current amps are made to use with a 20A circuit. XPR looks like it has a lot of power. Ground pin on a 20A power cord cannot be used with a 15A wall outlet.Help!!!!!!!!!
My current system
Polk RTI A7, Paradigm monitor 9
B&K 7250 reference II
Parasound HCA 1000A(4 amps)
Parasound DAC 1100
MSB Full Nelson DAc
4 Monarchy audio DIP units
2 sherwood 9080 AV preamps
Cambridge Audio CD-6
Marantz CD67SE
Monster power conditioner
2 Sansui tuners (TU-517,TU-417)
Speaker cables from XLO,ZU Audio
Digital cables,XLO,Tara labs,Wyde Eye Apogee,Monster,(coaxial and XLR)
analog cables- MIT,Tributaries,Monster,Audioquest,Vampire Etc..Etc..
Acoustic Research powered subwoofer with 300W amp made by Bob Carver
Marantz SACD player
LG blue ray player
Sharp HDTV
Pro-Ject turntable,Shure cartridge,DB System phono preamp

I believe they said at the show it would work with a typical 120V 15A circuit...due to the fact that it is a Class H....they're clearly concentrating on efficiency...

Joel,
Thanks alot for quick reply. Is it housed in the same size box as XPA-2s?

That photo is of all the 5 channel Emotiva amps....The first one in the photo is the XPR...I believe they are 5R chassis height...so they are taller than any of their other amps...You can pick out the XPR from the rest because of the large LED screen on the front...it has a meter bar for every channel...I'll post a photo of the XPR-7 in action so that you can get an idea of what it will look like...

Sheez!!!!!!!! The darn thing looks like a battleship!!!!!!! Have you had a chance to listen to any XPR amps?

I heard that XPR-7 you see in the photo at Emofest...it was in the theater room of the new building...that system was amazing...it also had 4 Ultra 12 subwoofers....We are talking home theater though...which in my opinion is a little less critical on sound quality (at this level)...than 2 Channel listening...it seems to me that theater is about lots of components that make up the whole experience....don't get me wrong, i don't think that a panasonic 5.1 setup from walmart sounds good....i just think when you step into this high end gear...home theater offers a little more forgiveness...the XPR series is based on Class H amplification...which is perfect for what they wanted...huge power, cool temps, and relatively efficient on power (how efficient can a 2500 watt amp be ;D).... I know how people on these forums are.. and I don't want to start another thread that turns into an engineering term paper...but I prefer the sound of a good class A/B amplifier over D or H....but....that being said, if my system was all about home theater...then I would go big with the XPR's....but my system shares its time with a lot of 2-channel listening...

As you can see from my set up,I am a big two channel fan.I mostly listen to music.The reason I thought of buying XPR-5 is, since it has a lot of headroom and dynamics because of reserve power,it could help me to hear everything in a recording.Don't get me wrong.My B&K 7250 Reference is class A/B and it sounds pretty good with a lot of details. But getting a new piece of gear is always exciting(like a kid with a favorite toy) I also own four Parasound amps in another room system.I just want to find out about how sweet XPRs could sound.Thanks

Absolutely!! I love getting new gear....I won't be surprised when I'm at AXPONA next year that I walk away with an XPR myself...blue lights always get me....If you get one, I'm sure you will be very happy!! They are definitely beasts!!  |

How would the XPR-5 perform against a XPA-5 in normal stereo ?

more than likely sh** all over it...

why buy a XPR-5 for stereo ? Why not buy 2x XPA-1 ? I thought emotiva they said that XPA-1 would be on the same par as the XPR's ? |

"Electronic amplifier" "From Wikipedia, the free encyclopedia" en.wikipedia.org/wiki/Electronic_amplifier"Class AB is widely considered a good compromise for audio amplifiers, since much of the time the music is quiet enough that the signal stays in the 'class A' region, where it is amplified with good fidelity, and by definition if passing out of this region, is large enough that the distortion products typical of class B are relatively small." "Class AB sacrifices some efficiency over class B in favor of linearity, thus is less efficient" "It is typically much more efficient than class A." "There are a variety of amplifier designs that enhance class AB output stages with more efficient techniques to achieve greater efficiencies with low distortion. These designs are common in large audio amplifiers since the heatsinks and power transformers would be prohibitively large (and costly) without the efficiency increases. The terms 'class G' and 'class H' are used interchangeably to refer to different designs, varying in definition from one manufacturer or paper to another." "Class G amplifiers (which use 'rail switching' to decrease power consumption and increase efficiency) are more efficient than class AB amplifiers. These amplifiers provide several power rails at different voltages and switch between them as the signal output approaches each level. Thus, the amplifier increases efficiency by reducing the wasted power at the output transistors. Class G amplifiers are more efficient than class AB but less efficient when compared to class D, without the negative EMI effects of class D." "Class H amplifiers take the idea of class G one step further creating an infinitely variable supply rail. This is done by modulating the supply rails so that the rails are only a few volts larger than the output signal at any given time. The output stage operates at its maximum efficiency all the time. Switched-mode power supplies can be used to create the tracking rails. Significant efficiency gains can be achieved but with the drawback of more complicated supply design and reduced THD performance." |

What? This answer response doesn't even make sense. Australian slang meaning to beat easily. I got that. Ok, let's reword: ausman: more than likely beat it easily BillBauman: What? This answer response doesn't even make sense. In other words, what does beat it easily mean? And how? And why? This answer still makes no sense. There is no 'win' here. There's more power, and both should be clean power. At best there might be a difference in the sonic signature, some flavor of some sort, but that's doubtful. When the XPR amps hit, I'll probably get one if I can. I'll be happy to do blind A/B's for all. Anyone that can tell a difference gets a popsicle. |

on a power basis the xpr-5 will likely sh** all over the xpa-5 given both have different output ratings..
you're comparing wattage outputs, I would say it be closer to xpa-2 or xpa-1 in terms of output per channel..
i would stick to 20 amp load for your fuse box..

Any timelines for the XPR line to be on sale? Or is the quiet answer: that's why all of the other emo gear on sale...
