I listen almost exclusively to classical. . . with a lot of small string chamber ensambles. Try the Furutech Evolution II wires, for highly neutral and musical sound throughout the frequency range. Audioquest Sky may even exceed these Furutech in extension and sweetness of treble, but become less well defined starting from lower midrange downword.
