6 ohm speaker WHAT TAP

I have a pair of 6ohm bookshelf (quad 12l) speakers and a TAD CAYIN TA-30. The Cayin has 4 and 8 ohm taps. What tap should I use with these speakers?


I would go for 4ohm tap. Better bass control.
Try both and use the set that sounds best.
I have the same thing and use 4 ohm.
