i have used rogue 120s in triode and berning 270 (with vsm-ms). these are very different sounding amps. i am hooked on the otl sound (my personal tastes) i think what your are going to find is that the merlins will take on the amps characteristics. as for balanced i am using the batbam and it is single ended. i am sure you could order one that is balanced. so i cannot help you there.
these speakers are very neutral and i really enjoy mine.
