Question about speaker configuration with current preamp/amp


I have ASCENDO System E speakers which have a selection switch at the back depending on which amp is being used. 
This is what is stated in the speaker manual: "Switch in position VD-N • This is recommended for fast transistor power amps. Switch in position VD-H (Standard) • Recommended for transistor amps with strongly load- dependent output-power."
I am running the speakers with a VAC Standard Preamplifier (limited edition) connected to a Mark Levinson 23.5 amp.
Which position should I have selected on my Ascendo speakers?

Any input would be appreciated.

This is for tube amps.

It sounds like they have an impedance correcting circuit. Nice.
