Quit being a sissy lala Nate. The XPR is a lightweight compared to my 125lb Cinenova. So now 200, or 3-- I must be in that .01% then. ;D Just curious, have you had the chance to try out a high powered amp in your system before?? You might be surprised at the results. So now 200 or 300 watts isn't considered 'high powered' enough? At any rate, the percentage of those who have tried a 400 wpc amp is very small. Like I said, only .01% or so of home theater owners would actually need this amp. Those with rooms 30' x 50' or more. I don't need that in my 14 x 25 foot room with my 93 sens speakers, but go for it if only to impress your friends. My next 1500+ purchase will be a pre-pro, not another amp. 30x50?? .01% Not sure where you're getting these numbers from, but I have yet to know anyone who has said, "I have too much power." My room is close to the same size as yours (though my speakers are a little less sensitive at 91db's) and in my system I have noticed a big difference in performance with the higher power amps. Granted its not a "NEED" thing, but then again if you're on a online audio forum you're probably passed the "NEED" thing. I find that most of the time when people say higher powered amps are not needed, is because they associate high power amps with high volumes, which is not the case at all.

Hey Eric, I'm not a sissy, if I do end up buying a XPR-5, I'll hire someone to put it in the rack! Not only a sissy, but a lazy sissy! ;D

Looking at the internal guts picture, are the capacitors and power transformer underneath the amp modules? If so would love to see a lower layer photo!
So I assume you need either a 30 amp 10 gauge 120 volt circuit or a 15 amp 240 volt circuit to power this monster?

Nobody "need" an amp like the XPR-5.
What an audiophile needs is an amplifier that can safely drive the speakers to the audiophile's desired listening level without the amp clipping.
Edoggrc51 is absolutely correct that many audiophiles associate high powered amps with high volumes. It is the same as associating a powerful car with speed. Sure, they (amp & car) can accomplish your imagination. But not on their own. There is always an audiophile or driver who decides how loud or how fast.
High powered amps assure that there is sufficient power to meet dynamic peaks which can be an order of magnitude above RMS requirements. Sometimes 5-10 times the RMS. No, you don't need one. But it is a good insurance policy if you want to make sure that you hear everything in the presentation as it was recorded. And remember, use the damn volume button on your remote ;D

Congrats Emo! Nice looking piece. Jam and edogg are right it's not all about high volume. When I was a DJ I used all sorts of PA amps. I started with an 800 watt amp and it sounded good but when I moved up to a 1.3K watt amp the sound was just so effortless. Even the low level presences was outstanding. I'll be looking forward to the XPR 1 and XPR 2.

Happy 4th Rad:
For me, unfortunately, I have space for 1 amp. And it will have to be an high powered, 7 channel amp. I just wished that this bad boy was packing 7 ;D

So what you're saying is this thing is overkill for my Klipsch RF-7s? I've heard of people running Crown amps at 500 watts and more per channel on RF-7s and loving it. I'll enjoy the head room and trust me, I'll crank that volume knob up more than a few times when I want to blow the socks off of someone in the theater room! ;D

I have Magnepans, I need XPR. If your existing amp is bridgeable try just playing one channel bridged and without. Get ready to jump into high power band wagon, you will experience what control is like.

You can use any amp with any speakers as long as you know what you're doing. You can never have too much head room, IMO.

Here is another thought for getting a high powered amp. In today's frequent change of models of electronic components, your power amplifier is the one component you really don't need to change for a long time. That can be so only if such an amp is capable of driving any speaker(s) that you are likely to purchase. And from time to time, we all do change our speakers. You just can't go wrong with a powerful amp. I'm getting a 7 channel one ;D

I just wished that this bad boy was packing 7 ;D Thanks Jam have a great 4th! ;D I don't know that I'll be able to afford a pair of XPR 1s but I think I can find the budget for a XPR 2! ;D I better start saving now....

Actually you CAN have too much power; but it's really really high.
I currently run 8400watts into a pair of B&W Nautilus 803's... However I've never seen it consume more than 500watts RMS per side, even at ear melting levels.
and before you ask, yes it sounds better* or I wouldn't have done it. (* and yes, at any volume level.)
99.9% of the time it never makes it out of 1st gear, as you could imagine.
My rear speakers are only 120watts and on loud movie peaks back there you can hear the distortion creep up when it runs out of steam, if one didn't know any better you wouldn't even know. So the XPR-5 is on my radar of interest for the distant future; my current focus remains the XSP-1, that makes the greatest sense for a mostly-music system, up from the UMC-1 I use in 2-ch direct mode.
My 2 cents.

wizardofoz... The amp is fully differential...just look at the Input Impedance...you can see that 47kOhms for unbalance (which is pretty standard) for Unbalance, and 22kOhms(balanced), the lower the number basically is an indication what type of amp it supports... So far the XPA-1 and the XPR-5 are primarily Fully differential...

jamrock, Nobody "need" an amp like the XPR-5.... In reference to your comment...I would say that all we need is food, water, clothes, and shelter...you know how it is...lets let people enjoy the luxury's in life...who needs a yacht, not me, but boy I would like to have one..., I would also say the same about the XPR-5...it is a luxury that some people just got to have, if you know what I mean.

Jerry, according to emo, only the xpa-1 is the only amp that's fully differential, unless they changed their minds.

Jerry, according to emo, only the xpa-1 is the only amp that's fully differential, unless they changed their minds. Check the product page. "Fully discrete, dual differential, high current, short signal path Class A/B amplification with Optimized Class-H™ power supply topology."

XPA-1: "Fully balanced, quad differential input stage, with cross coupled active current sources."

XPA-1: "Fully balanced, quad differential input stage, with cross coupled active current sources." Re: Emotiva XPA-200 - What can we expect? « Reply #23 on Jun 2, 2012, 7:24am » "Hi guys, The XPA-1 is the only Differential Reference amplifier in the line for now. It is designed to complement our other Differential Reference components, such as the ERC-2, the the XSP-1,etc. All of these components features truly balanced circuit topologies (not just balanced connectors). We are working on a baby brother for the XPA-1 but it's not something to think about until next year. Now as far as lines are concerned, the XPA Series is not being replaced by the XPR series. They are two distinct lines. X is our core line. This is the heart and soul of Emotiva. It will also be our largest line of products. Ultra is our value line, designed to bring high performance audio to you at prices that make great sound affordable to anyone. X Reference is our "no holds barred line", and as a general rule, it will all also feature very high power amplifiers! (You can never have too much power) It is the designed to be the biggest and the baddest. We'll put XPR up against anything out there. There are no plans at present for an XPA-700, however we are working on an new XPA-7, as has been previously noted elsewhere. Hope this helps, Cheers, Dan"
