I always have a difficult time wrapping my mind about what are the attributes that audiophiles value concerning what is or is not "musical". Euphonic, somewhat exaggerating harmonics or overly rich, decidely not accurate, might be considered musical to one listener while "accurate", or more neutral could be of greater value and considered more musical to another. The reason there are so many differing opinions is that each of us value different things in what we hear and perceive. The question is impossible to answer but to the individual listener. In any case the amp and speakers must work together for starters. Going back to a review I read back in the mid 80's in "High Performance Review" in comparing the solid state Krell KMA 100 mono amps to the all tube Audio Research M100 mono amps the reviewer asked how can two amps that both sound so "right" can at the same time sound so different?
