One further thought: From the perspective of the amplifier, by using the Goertz cables in a biwire configuration you are doubling their already extremely high capacitance.
I don't know if the biwire configuration of the MI-2 provides one pair of terminations for each channel at the amp end or two pairs, but if it is physically practical to do so I would certainly try disconnecting one of the two runs at BOTH ends and putting jumpers on the speakers. That would cut the capacitance in half, although it would still be much higher than the capacitance of most other cables.
Good luck. Regards,
