I have a ML 334/380/390s combo with Audio Physic Avanti Century speakers. I had Audioquest Diamond X3 ICs with Dragon 2 cable. I changed to Harmonic Tech Pro-Silway II's and Magic One ICs, with Pro-9 speaker cable. I found the Harmonic Tech cables much more open and detailed compared to the Audioquest cables. The change was not small.
Good Luck
