Dave, that's the only component not made in North America. The cabinets are made in China. Even still, they're gorgeous. The only caveat I have applies to all equipemnt components: synergy! Some speakers mate well with some amps but not well with others. If your S2s work well with your Bryston amp, I surmise they'll work well with the S8s.
I don't know how heavy the Bryston is. I think it's solid state, so it may not be too heavy. If it's not too much of a PITA, I'd bring your amp to the dealers who carry the models you're interested in to check synergy. OTOH, I have a feeling that solid state is solid state. So if you A/B speakers, just make sure the dealer is using a solid state amp.
Finally, there's no such thing as perfect anything. Every component, speakers included, has its own unique presentation. So in the end, go with your ears.
Lastly, your sound room has a major impact too. Unfortunately, you can't bring your sound room to the dealer. But some dealers may let you take a set of speakers to your house. Problem there is that the higher end speakers weigh a ton. The S8s weigh 100 pounds each.
Good luck. Please let us know what you decide.
