owning yvette’sSame wave length, exactly why I posted put "very" in front of comfortable with 4ohms
regardless i find the speaker to be so musical and sweet on top that a neutral SS amp mates better for me. i prefer the resolution and detail of ss. ymmv
As the Yvette’s dip to 3ohms around 100hz also where all the muscle from an amp is needed.
Not to mention the impedance /-phase load around 56hz Stereophile mention.
