My current set up is:
2 XPA-1 --> 2 Focal Electra 1038Be XPA-5 --> Focal Electra CC1008Be, 2 Focal Electra SR1008, 2 Focal Electra 1008Be XPA-3 --. Reserved
In the future, when a better Dolby Atmos Pre/Pro is available, I'll add 4 Focal Electra IC1002. Hence I need a mono block to drive the center speaker when the XPA-3 and XPA-5 will take care of 4 surround and 4 ceiling speakers.
My question: Do I need another XPA-1, or is XPA-1L sufficient.
Thank you.

Though there probably would be no sound difference or very little, I would personally stick with the XPA series.

For a center channel even the XPA-100 would do, or XPA-1L if you don't mind the extra cost.

I find the XPA-100 to be a perfect match to an XPA-5.

Nick The only XPA amp I haven't owned are the XPA-1's, running all other XPA amps on My Monitor Audio and Chane Audio Speakers I have noticed zero difference between the amps, that's just my findings of course but even running my 1L's in Class A mode I noticed no difference, maybe I need more resolving speakers ? who knows haha, there is a certain something about owning the 1L's though, they are really pretty . We each will have our own findings which makes it so hard to recommend a certain product to someone else with different equipment, room and ears

I would just get rid of all those speakers and keep the two you like the most....Two channel rules...

For movies the center channel is the most important channel. If you are running xpa1's for mains. I would go why another xpa1 for center. Don't skimp.

I like your thinking BUT,,,,,,,,,,,,,, that kind of thinking would require me to purchase another XPR-1 for my center, I just don't see the required need for that much power to the center channel unless of course their playing 5.1 music at loud volumes. This , I know, sounds very contrary to what I have espoused since I've been on this forum but,,,,,,I just don't think you'd need that much for movies. Just my opinion, but definitely go with a MONOBLOCK!!!! ,,,,he,,,,he,,,,he,,,,,,, CEO

This thinking makes no sense.
For two channel what's the most important? L and R obviously. So you run them with an xpr
For Ht or 5.1 music what's the most important? The center. So it's backwards thinking if you don't feed it with the same importance of power. If you feel the center doesn't need that much power for Ht then you don't need that much power for 2 channel either

If you feel the center doesn't need that much power for Ht then you don't need that much power for 2 channel either In 2-channel mode, people often listen with speakers set to full range. In these cases, the bass frequencies require the most power, which in turn demonstrates the need for a high-powered amp. When it comes to HT, I think a lot of center channel speakers are more efficient than speakers designed to be used for 2-channel use and thus don't require as much power. Also, in HT speakers are not run at full range but subs are used for the bass frequencies which means the power requirements are not as high as for doing full range in 2-channel. Of course it won't hurt to run a center channel with an XPR-1 or other monoblock but in my opinion amp power isn't as critical for a center channel in an HT set up as it is for L/R in a music setup. In all cases one should pay attention to the quality of the amp, though.

So I guess I assumed that was the deal with the 2 Channel as well.

I forgot to include the Rythmik E15HP sub. The system is used for music/movie = 50/50. in 2-channel mode, the XPA-1 pair will drive the Focal 1038Be full range (40w-400w) with HT bypass. In HT mode. all speaker are set to small with different frequency cutoffs. The center speaker amp only need to power from 40W-200W and hardly reaches 200W with 40Hz cutoff. I think I should take Creimes's advice to buy either XPA-100 or XPA-1L.

The 5 speakers should create a larger more open soundscape requiring less power, the processor makes this happen, Only in two channel listening would you require more power to achieve equal decibels.

That's not how it works. Since it's not all 5 speakers playing the same thing at the same time. If you were playing all stereo (basically stereo out of all the speakers aka party mode) then maybe. But with movies it's the same setup as 2 channel. At many times the center channel is the ONLY speaker emitting sound. So if your argument were to be true, then the center would need MORE power since it is playing by itself at times

I have two more days before Summer sale ends with my E-club membership. Should I buy XPA-1, XPA-1L, or XPA-100?
Focal Electra CC 1008 Be specification:
Frequency response (+- 3dB): 55Hz-40kHz Low frequency point (-6dB): 50Hz Sensitivity (2.83V/1m): 91dB Nominal Impedance: 8 Ohm Minimum Impedance: 4.1 Ohm Crossover frequency: 500Hz-2200Hz Recommend amplifier power: 40W-200W

Are your XPA-1 amps gen1 or gen2, only asking due to matching styling. My center speaker I run is a Chane Audio A2rx-c and has a 88.5db sensitivity and runs fine off my XPA-5, then again if I had the money I would like to own an XPR-5 just cause . Chad
