Vandersteen, Audio Note, and Resistance


I have an Audio Note Kit Four, which is a 10w tube amplifier. It has 3 speaker posts per channel - one black, one 4 ohm red, and one 8 ohm red. 

I am trying to connect to Vandersteen 1c speakers, which claim to be 6.8 ohm (+/- 2 ohms).

My question simply is: which binding posts do I use, the 4 ohm or the 8 ohm? I am getting conflicting advice between my friends and youtube.

Try either. :)

It's not going to hurt you, but you may hear one is really better than the other.

Pay particular attention to the mid-bass and treble.
Just saw some more youtube vids. Apparently, I need to be concerned  about over-heating the output transformer if I use the 8 ohm posts.
