Are you saying that people who have electrostatic or ribbon or planar speakers where the load impedance dips below 2 Ohms are not enjoying quality sound & that they are merely reveling in high SPL music environments in their respective homes?????
No, what I am saying is that if those 'electrostatic or ribbon or planar speakers' were higher impedance the owners would be enjoying even better quality sound.
We can look at this from a very basic point of view. If a speaker has a reputation of being 'difficult to drive' due to low impedance, the reason that phrase is used has to do with the fact that the amplifier has a difficult task. Don't think for a minute that there is no price paid for that! The amp simply will not sound as good.
In addition, speaker cables get **critical!** when you are driving lower impedances. With higher impedances the cables are far less critical and can be run longer distances.
