For the price of the Focals you could almost be looking at the JA Perspectives. Anyway, I think the fact that you like the JA house sound is a good indicator although certainly not definitive. Also, the Focal tweeter is very different from the treble you get from a JA fabric dome, so that would be something to look for upon comparison. Markalarsen probably has some good insight to the differences between the two although he had a previous Focal model. These are not huge speakers, so if you have dealers of both nearby I'd arrange for an in-home demo and you'll have your answer pretty quickly I'd think. Personally I think the Pulsar is a much better looking speaker if that's even a consideration, although you may feel differently. By the way, just out of curiosity, what's your center speaker?
One last thought. Whatever you ultimately choose and given the quality of your amp I'd strongly recommend trying a good stereo preamp that could be seamlessly integrated into your surround system. As good as the 8801 may be, it could very well be a significant bottleneck to the performance you can ultimately achieve for stereo. IME the preamp is one of the most important contributors to a system's sound, so it's at least worth a look. Anyway, best of luck in your search.
