I for one can say I auditioned both the Rowland 201's and the 501's... while some areas were alright, they didn't grab me the way the Rowland 302 does.
I did purchase, and do still own an ICE based pair of monoblocks that continue to amaze me... they don't look as good as the jewelry casing of the Rowlands, however the Rowlands don't sound as good as what I purchased... IMHO, and as always, YMMV... only advice I can stress is audition *any* of the amps with your own gear, as some of these are more critical of system matching than others as well...
