U2 was very good too ! Had superb bold sound, great soundstage and crisp bass. Infact the U2 had a biggest and widest imaging when compared to the other two.
I felt the N200 was slightly down on dynamics over U2 and RS130. It had great mid range and maybe more natural bass.
RS130 the mid and highs were totally outstanding, literally they opened up the soundstage vertically.
In my opinion (in the several tracks i heard), the N200 felt half a notch below both U2 and RS130. Not that N200 is bad, but there was some magic missing in it, which was found in varying degrees in U2 and RS130.
