The best system I have ever heard anywhere ever is my friend's Statement NAC S1 with three NAP 300s driving active Naim Ovator S-800 speakers. These speakers were launched not long before Focal got involved with Naim so unfortunately were soon discontinued, but they are astonishing in this set up.
After demoing a few pairs I ended up with B&W 804 Diamonds through my Naim system (which was a NAC 552/ NAP 250 but is now NAC 82/NAP 180) and find the combo a brilliant pairing. The 804 Ds are an especially good floorstander for smaller rooms with any bass issues.
I find the Naim/Focal pairing unsatisfying when I hear it at shows: harsh and with glare.
Ultimately though a speaker is room dependent. Please home demo speakers before buying as their character can vary massively by room.
