For me, I love the flexibility as I'm planning on keeping my 7 for many years. It's very easy to split them up, move them around, use them differently than a single multi- channel amp. Nobody's really right or wrong, just personal preference and $$ available to spend (as we all know it's easy to spend allot of money in this hobby)

I'd be OK with them for a center or surrounds but not mains. Too weak. Wasn't that your original question? Getting 5 1Ls? It was but then many mentioned using xpa-1s for the mains. I have to admit... I'm leaning toward just adding two xpa-1s and using the xpa-7 for the rest and if I ever go atmos and add ceiling I have room to grow and if I don't well then I have plenty of headroom. |

Okay what do you get? Isolation. No shared anything. No Crosstalk, the ultimate yes from the previous nos'. All reference systems run mono blocks. There is a reason. I tell everyone if you have a chance to go mono blocks, only good can come from it. Our mono block society here will vouch for my assertion I am sure. So Vince, are you telling me that I should call and order the last 7 XPR-1's before they're gone?  Well....let's see... 7 x XPR-1s...I can't see a down side here. |

You could do what I did for a while.
I ran my L/C/R all with XPA-1Ls and used 2 of the Mini-Xs for my surrounds in a 7.1 system and it worked really well.

To get 72dB of dynamic range takes about 80-90% acoustic absorption and a dedicated room. It is worth the effort though versus an untreated room for other reasons too. Just cover all your walls with Owens Corning 703 4" panels wrapped in fabric. Also add some 8-16" OC 703 bass traps (by gluing multiple OC 703 4" 4'x2' panels together). You will not believe the sound improvement if you do this. I've had audio professionals (engineers, store owners, installers) hear my setup and they are always floored by how great a dead room sounds. You get a more stable power supply to handle extreme transients. It totally depends on speaker impedance, efficiency and listening distance though. It is possible to reap no benefit, but if someone wants to future proof for all possible speakers they may own in the next 15 years, nothing but good can come from having extra head room. I don't think the crosstalk difference is audible, there are tests online to blindly see what dynamic range you can hear (in your room on your setup). I can barely pass the 72dB dynamic range test (-72dB down from a normal listening volume) : www.audiocheck.net/blindtests_dynamic.phpNo way could I hear no crosstalk versus -120dB of crosstalk. Definitely though, I love mono blocks now that I have them! well in a noisy enviroment w/ the laundry running about 14' away and using my grado sr125 headphones i'm only good for 54db. i got 8/10. Good find on this I'll have to do it again on my main system when it's quiet in the house. |

haha no.
I'm not deading my room and sound is biased anyway, sounds good to u sounds crap to me.

Well, it's your call. It's not overkill though. What would be wrong with just doing two xpa-1s and a xpa-3. Your saying that keeping the xpa-7 to use for only 3 channels would be better than the xpa-3 then I thought you were talking about 5 Xpa-1l. That's not overkill if you want to go for it |

Lol, that is true. If you are going for audio fidelity though, I can promise you my system is very likely the best you've ever heard. A room covered with absorption is going to sound infinitely big, not dead  So the image will actually be much deeper and wider since you are able to fix impulse/etc plot. Taming the waterfall plot at the same time with bass traps means incredible dynamics in the bass region too. No BS, if you are near Columbia, SC, I'd love to show you. I too believe hearing is believing. haha no. I'm not deading my room and sound is biased anyway, sounds good to u sounds crap to me. |

Thanks! No big balls here though, just average ones (e.g. I'm a pretty nice fellow). I spent more than a few years studying acoustics and REW (room eq wizard). Combined with world class Emotiva equipment, great Klispch Palladium speakers (with ultra low distortion up to 120dB), and matching subs I have reached audio nirvana (provided someone wants to hear what is recorded and loves that "live" sound, some don't and there's nothing wrong with that). I can tell you after visiting 10-20 high end audio shops in the last 10 years, I've never heard a system as clean as what I'm running. Unfortunately, a majority of these high end audio shops can't setup a system properly. The problem is it takes a lot of acoustic work and study to get there, and they are only concerned with making a quick buck. Attached are some older REW plots, but anyone well versed in acoustics would be very impressed by them.    Lol, that is true.

I have a set of XPA 1Ls. Weak is not a word I would use to describe them. More power than the XPA-7. So if the 1Ls are too week the 7 must be completely anemic. two 1ls vs the xpa-7 running two channels the xpa-7 is twice the juice. One member mentioned dual xpa-1s for the mains and use the xpa-7 for the center/surrounds. This is spot on recommendation and is now on my to do list. I think that'll be plenty of overhead for my system. |

I think that'll be plenty of overhead for my system. The XPA-7 does have more power if running only two channels but not too many people bought it strictly for two channel use. The XPA-1Ls put out the same power whether using 2 or 5 or 7 channels and the fronts won't be dragged down by surround use. Having said that, the XPA-1s for the front with the 7 handling everything else will work very nicely although that's a lot of amp for surround duty and might actually be overkill. |

Overkill is good. Who knows I may move to 5 towers that are 4 ohm demanding type.
