I have N802s which I love, and am currently evaluating the 559, with a Meridian preamp.
I usually use a valve amp, so am pretty picky about SS amps, but my early impressions are that the 559 is a stunning amplifier, very powerful yet subtle and musical. 802s really open up and sing.
The 559 easily betters a JRDG Concentra II that I've tried as well (not enough power for the N802s in my opinion), even though I have been impressed with the musicality and amazing build quality of JRDG stuff (separates would be tempting ...).
Interestingly enough, I have found that the Meridian 501 preamp was almost as good as the costlier 502.
Hope that helps.
