Those prices are not for genuine B&O ICE modules, are they? More likely for some class-d knock-offs? ICE the real deal, I've already built 2 kits for my parents. B&O used to have price fixing for all their modules but that has changed in the last year. The company I can get that stuff from are a spinoff company of acdelco. I can order them through our parts supplier from out work!

For me, I would not want or need a 7 channel amp @ 200/300 or more wpc. I like having more power at the fronts because I use them for 2 channel music as well as movies so I like the idea of an XPA-2 or XPA-1s or other monoblocks for the fronts. Overkill? sure but that is what makes this hobby so much fun. ;D
If room is an issue, then sure a 7 channel amp would be nice. Although I wouldn't buy one, I can see where it would appeal to many people for different reasons.

Thats the beauty, customize your amp any way you want it, just like burger king!!!! lol

yes i like a 2channel setup as much as the next guy though I wouldn't be buying something like usp-1 to handle that option. What did you buy your USP-1 for, then; a doorstop? I was just kidding before but this has me wondering. Or maybe I understood what you were trying to say? what ever you decide to do lonnie 1 thing i would like to see is support for 3,2 and 1 ohms ratings having this option in more important than anyhting that has been discussed as some speaker we use within our system will dip into and under 3 ohms this should be catered for.. I believe it's been stated that Emotiva amps already have this capacity (to handle momentary dips down to 2 ohms). Unless you're powering car speakers (usually 2 ohm nominal) I don't think they would need to build a 2 ohm continuous rated amp. But, if you are saying that you want them to continue to be built to handle what the current line up does then I'm with you on that!

And, from a business perspective, you can charge more for the modules than what you could buy a 2, 3, or 5, channel amp (when factored for the cost of the chassis) for with the big cost save being if you buy 7 modules at one time!

Seven channels of 140 watts? Very intriguing. It would need to have better output than the UPA-7. A bigger power supply, better crosstalk, THD and s/n numbers. Apparently the 7125 is Outlaw's best selling amp. It doesn't have XLR's or LCD lights. But it does have great specs and apparently performance.

^The XPR-7 would have trounced it, but apparently that's off the table.

If you have a 5.1 system, you would have no need for a 7 channel p/amp of any power rating. However, for those of us with 7.1 systems, we too like excessive power whether it is a 2+5 or 7 configuration. Some enthusiasts prefer a 2+5 setup because they use R & L towers for 2.1 or 2.0 listening. Others like myself, use a suite of 7 similar speakers and prefer a 7 channel amp. We are grateful for the extra headroom when using it for 2 or 5 channel sources. And when the discrete 7.1 source comes along, we are just at home hearing it in all its glory. If anyone wants to stay at 5.1, go for it. Just don't make it seems that those who want 7.1, 9.1 or even 11.1 should not have our joy as well.

jamrock have you a/b comparison between power output between an avr's vs power amp amp section..
generally I would agree power doesn't make much difference though did you where your dial lays when when cycling between -35 and 0 when comparing 180/230 watts x 7 vs 200/300 or 200/350 x 7..
to be honest i never use 8 ohms in context of ht anyway..
my opinion I would say go 3 release format for 7 channel, start at 180/240, 200/350 and 250/400 x7 let people choose what they want to with and if they want to upgrade they can, though support to all lower ohms is mandatory.. I also know this should be standard on current line amps as well...

Very little activity on surround channels, so high power seems to be a waste. I'd go for the 3x300, 4x150 route.

It is like proving that a straight line is the shortest distance between 2 points. I use the test bench analyses which clearly demonstrate that under real world situations, multi-channel AVRs CANNOT DELIVER even a reasonable approximation of their advertized power simultaneously, except into 1 or 2 channels the most

Power - Seven x 200+W Balanced inputs ?? Yes Cost - what price point is desired... be realistic!! $2000-$3000 Is class of operation important as long as it sounds great?? I am very interested in the XPR line and class H design, even without a 7 channel amp I am pretty sure I will be buying the XPR-5. And also PLEASE move towards this design as it looks 10X better than your current gear!! i1141.photobucket.com/albums/n591/mkbenchmark/IMG_0408.jpg

Seven X 140 watts = Emotiva UPA-7 = seven X 125 watts
No difference

I am currently considering the W4S 7 channel - 3-500watt and 4-250 watt. Having an XPA-3 at 200 watts, I want a serious power upgrade for the front 3 channels and the XPA-2 while a great amp is not enough to meet my desires. I favor a slot configurable amp with 2 or 3 power options.
As to a 7x140 watt amp, other than to enthusiasts here, I don't think it will sell well to the general public as so many consumer receivers have that "claimed" power rating.

I use the test bench analyses which clearly demonstrate that under real world situations, multi-channel AVRs CANNOT DELIVER even a reasonable approximation of their advertized power simultaneously, except into 1 or 2 channels the most Harmon Kardon AVRs have been shown to use realistically accurate power ratings, as do many of the more expensive AVRs out there. In any case, requiring full output from all channels at once isn't a realistic requirement. To the question in general, I have a 7-channel A/B power amp rated at 185W into 8, I can get my fronts to deafening volume and it doesn't even get warm let alone start to clip - power is all about headroom, and this is decided by your speakers, your room, and your listening preferences. Question is, can (eg.) 300wpc be delivered at a price that makes it good value for people who won't even approach half of that power requirement?

In my experience I have yet to hear an AVR meet or exceed the sonic quality of a well made separate amplifier. That's not to say they don't exist, but unless you have poor speakers or are deaf as a post I just haven't heard it... yet.
