Dan and Lonnie -- thank you for confirming the upcoming XMR-1. Given that it will have 16 fully-balanced channels, the obvious question is whether you will be developing new fully-balanced multichannel amps to mate with it. I assume the answer is yes, because the benefits of a balanced processor are lost with a single-ended amp.
We would appreciate any info you can provide.
Thank you, and keep up the great work.

Thank you, and keep up the great work. 45 - 75 wpc amp similar to the Sherbourn amps should do the job nicely, as long as they use true XLRs connections. Emotiva does have the background for these type amps. Should be an easy solution for Lonnie!

45 Watts? You must be joking! Last time I checked, the PA 7-350 had a bit more! It's no distribution amp... I reckon about 150 Watts is the least we can aspect for a HT amp.

I agree with you Erwin. 45 wpc in Class A maybe. I would expect their new flagship amp to supply a minimum of 75 wpc @ 8ohms for any support channels and at least 125 for the five main channels.

Outlaw sells a number of excellent balanced multichannel amps (designed and manufactured by ATI) that would be perfect mates for the XMR, but I would prefer to stay within the Emo family. Perhaps the XPRs could be re-engineered to deliver half the power in balanced mode.

A 16 channel amp?! Nah. Considering most of those channels are all surround channels, I think a separate lower power amp that just powers the surrounds would be better than cramming 16 high power channels of amplification. Remember this is still a niche. Creating such a gargantuan amp would strain the profitability for it.

Any elite Emotiva amp they are planning to pair with it with an expectation to power all of those channels should give more than enough power for any in ceiling speakers you can throw at them. I can see an escalated price point for this elite level product and would think people would pay accordingly.

I can see an escalated price point for this elite level product and would think people would pay accordingly. Cost aside, this fictitious amp would be HUGE!I'm with Garbulky. I'd make a 6 to 12 channel amp with 80 or so class D amps per channel. Leave it up to the owner to make up the rest of the channels with higher quality, more expensive, class A or A/B amps. If I were putting together a 16 channel theater for myself I'd look for my center, mains, and wides to be towers with 200 to 600 watts per channel. The other amp(s) I'd make as small/inexpensive as possible. 2 RU or 1 RU if possible. I have had heights, wides, surrounds, and/or backs for almost a decade. The ceilings won't be any different in Atmos, you won't need more that 80 watts or so. The only possibility of Atmos catching on is to keep it as simple, small and inexpensive as possible. Peace

Why play around. 16 XPR-1 monoblocks.

Why play around. 16 monoblocks. 16 XPR-1s. Done! Would that be 16 pallets then?

I wasn't suggesting that Emo develop a 16 channel distribution amp. Instead, I was expressing interest in a full line of balanced XPRs -- 2, 5, and 7 channel amps.

I understand. I do agree that that's an area that's yet to be developed by Emotiva. So they would need 10 amp modules for an XPR-5 balanced, right?
unless there is another way to make it fully balanced.

16 channels to include ceiling speakers that makes me wonder... Why not add a couple more on the floor then? 20 channels anyone? plus the subs... I think it will soon be easier to deliver the sound directly to the brain!

The question is was Dan referring to balanced input to output [ a fair assumption admittedly ] or single ended circuitry with balanced outputs like the xmc1 and a lot of expensive pre pro's ; or can we put this to rest - duplicate circuitry for 16 channels is a chassis and a half Good chance imho that the atmos ceiling ? surround speakers may be class d depending on interpretation of what Dan said [ or possibly just for the new entry pre-pro ? ] Makes sense ; you dont need 200w/ch for sound object steering And class d is of course very efficient ; especially putting out the watts per unit surface area .. for want of a better phrase .. Found this interesting pdf for a balanced class d pwm [pulse width modulation] design ; intriguing www.crownaudio.com/media/pdf/amps/bcapaper.pdf

Remember this is still a niche. Creating such a gargantuan amp would strain the profitability for it. I was thinking something similar. First we don't need a 16-channel amp since full blown Atmos 9.1.6 only needs 15 amps besides the subwoofer's. I reckon a 12-channel XPR-12 with 150 W/ch for the surrounds and elevated speakers would be perfect. Then all we need is a XPR-3 for LCR speakers. 3 x 400 Watt sounds about right to me... Not that I will be buying the XPR-3 since I already have the XPR-5 and want to tri-amp the LCR. I need 21 amp channels in total.

My whole point about a 45 - 75 wpc amp was strictly for the hights and surround speakers, not the main 7 to 10 speakers but all of the other enhancement speakers around the room. Surly not all of the speakers need to have great power requirements to achieve the Atmos effect! Or have I missed something?

The Weiss DAC2 is like my Nike Pegasus 29 running shoes: perfect for the job and never draws attention. I don't even bother to turn it off. BTW, I now hate Nike for messing up the current Pegasus 31. They changed the midsole and my feet hurt after 10 km. I have sent them back. My good old Pegasus 29 are kept aside to run marathons.It just hit me that 2 Marantz MM8003 8-channel amps would solve my problem nicely as 5+8+8=21! I thought about keeping the XPR-5 where it is and getting 3 XPA-7 but since Emotiva isn't shipping them to EU... I might start to search for used MM8003 here in EU. They are 140W/ch (2 channels driven) which is perfect for the Surrounds and Heights and for the Mids and Tweeters of the LCR. The XPR-5 would power the woofers of the LCR and the 1st pair of Surrounds. Thoughts?
