Heard the Nemos last weekend at the NY hifi show hooked up to a pair of Talon Khoruses. The rest of the electronics were also Electrocompaniet.
I've heard the Talons before at length, and while the Nemos did deliver the quickness and dynamics these remarkable speakers are capable of, they seemed to artificially roll off the highs that with the Talons can be very extended and clear. I can't say for sure it was the Nemos doing this, as it could have been the source or preamp, but I've heard Electrocompaniet stuff does tend to sound a bit on the sweet side and that is what I heard--a bit too sweet for my liking. Also, I too read in Ultimate Audio that the Nemos were designed with the B&W Nautilus speakers in mind, and given their fussy metal tweeters I can see where they might be a good match, but not for the Khoruses in my opinion--it limits them.
That said, if you're into tubes or a more laid back kind of sound then you may be in for a treat. If you tend to look for a more neutral, detailed presentation I'd look elsewhere. Either way and especially at this price level you should go listen for yourself before making any decision. Hope this helped and best of luck.
