First World Problem in need of Solution

You probably want at least a couple hundred watts per channel.  The best solution would be to find more Luxman amps, but they are definitely very expensive!!  I don't know if you can find a smaller M-700u that you could run mono for the center channel.  Then another M-700u for the surrounds.  Be careful when buying these from Japan because the "Japan" models are usually wired for 100V A/C (which will not work properly in the US 120V standard).


Or you can try to put in a Pass Labs or Parasound amp.  Pass Labs does not make 3 channel amps, but Parasound has an A31.  Or use a Parasound JC1 for center and an A21 for surrounds.  The JC1 can be switched to high-bias Class A which may sound closer to the Luxman signature.  Or you could try a McIntosh 3-channel like the MC303, but the McIntosh will likely be a smoother sound than the Luxman/Pass/Parasound signatures. 

I would also vote for option #1 running your 2-channel setup in bypass mode. While watching films and TV, you'll be less sensitive to differences in the sound between your mains and other speakers anyway, and this won't compromise your 2-channel playback.

Ignoring the sound character for a second, you should pick an amplifier's power output for the other three channels based on how hard the speakers are to drive and what volume you want to achieve. I'm using a Bryston 21B3 as a 3-channel amplifier, as it is one of the few 3-channel units that is capable of high power output and drive.

My advice is build your home theatre in another room and get a couple of Jbl m2 and half a dozen subwoofers and some Jbl 1400 as sides and rears 

Sorry, nekoaudio, but I disagree here.  A large power supply in the amp is very important, yes, but the sonic signature and how it reacts to signal/load is another important factor.  I have worked with several different amps (Bryston is one of them) and when you combine a very fast/clean amp like Bryston with a very warm/full amp such as Luxman/Parasound, what happens is an imbalance in sound and impact.  In that case, while the Bryston is a very high resolution amp, it will just not keep up with the Luxman/Parasound in volume/body/impact.  I have tested and experienced this personally.  The Bryston does have it place, but also in this case, I think it would be a very bad pairing with Focal speakers.  The Bryston would excel with a very warm preamp (such as Marantz) and paired with warmer type speakers (NOT Focal).  In my situation, the Bryston could not even keep up with my Emotiva XPR-1 amps, and I was testing the big 7b3 600 watt monoblocks.  I probably could have gotten the Bryston to work, but I did not want to re-work all my cabling back to gold-plated connectors and such.  The Brystons were powering left/right and the Emotiva was powering the center -- and the difference was very obvious.


------
The Focals are very fast and clean speakers.  If you pair them with a high resolution amp such as Classe, the sound is not bad, but it is very apparent that the bass/midbass are somewhat thin and hollow sounding.  This pushes the emphasis to the high frequencies, which makes the speaker sound somewhat bright (bordering on harsh).  Pairing Focal with Bryston would create a very thin/bright sound with no body and impact.  The Focal definitely needs a very warm full amp because the speaker is such a fast responding speaker.

How do you like the Focal Sopra center? I have the No. 1’s in my dual audio/HT set-up. Thanks.
