FWIW, doing a search of "MC275" and "MC-275" in the
Audiogon Virtual Systems returns a total of 32 systems using this amp. Perhaps this is a good place to research speakers.
Excellent advice Tvad, and an interesting thread. I am also looking for some easier to drive speakers after straying from my usual muscle amps (300-500wpc) to a pair of 100wpc monos. Your speaker list above is very similar to some I have considered except Classic Audio Reproductions (which I know nothing about) and Merlin (which I doubt have the level of impact I enjoy). Unfortunately, I have never had a chance to hear Silverlines.
