Speakers for Electrocompaniet Nemo monoblocks?


Hi, my current speakers are JBL 250 Ti and they are extremely good, delivering the huge american sound with thunderous bass yet I hope that maybe later this year I can upgrade them to more refined Hi End speakers withe better imaging, details and tembres while keeping the big soundstage and bass that JBL's are known for. Right now I'm thinking about B&W 800 Diamond (used to have 802D and while I wasn't happy with their rather boxy sound I still miss their lovely tweeter that never called any attention to itself) or Wilson Sasha. KER 207 Reference sound like a nice choice as well as Vienna Music (though Vienna looks like it's designed for less powerful amps so driving it with monstrous Nemos makes no sense). Any ideas or experiences with Nemo driven systems?

At the risk of appearing redundant, I suggest buying amps for speakers, not speakers for amps. IMHO, it is far better to choose your speakers first, then find appropriate amplification.
Unsound, I agree that it's probably the right thing to do but since I already have the amps (which a lot of people rate as some of the best available) I guess I just have to do it this way.
I'm not a big B&W fan myself, but here's a review from several years ago echoing the posts here suggesting a pairing with 800Ds:

So it seems there's at least some consensus re: that combo having synergy.

You might want to also check out Revel Salon 2s. I have a pair driven by a Plinius SB-301, and let's just say that while I personally don't need more power, they are power hogs by design and wouldn't complain one bit about being driven by your 600 wpc monsters. And of course you should check out the Sashas too, with the only caveat there that they are not as forgiving of a less than perfect room than the Salon 2s.
How would you guys describe the sonic differences between Revel Salon vs Sasha vs 800Diamond?
