If I can point something else out: Just because your amplifier can drive to 2 Ohms and is able to double power as it does so does not mean its sounding its best when doing so. All amplifiers make higher distortion when driving lower impedances! If you think that distortion is inaudible think again- the increased distortion is audible as increased brightness, harshness and a reduction of detail (distortion obscures detail) because most of that added distortion is unmasked higher ordered harmonics.
Hi Ralph
I appreciate you pointing this out. It’s very often overlooked in these types of discussions. I have always failed to find the wisdom in designing low impedance/high phase angle (Difficult load) speakers that then require/demand massive amplifiers to drive them. An environment for the appearance of high odd order harmonic distortion.
