Two amps, one preamp, one sub…


So I just picked up a subwoofer, Elac 3070, which I plan on connecting to line out on my EAR 868 preamp.  But I have two power amps, Nagra PSA and Wavestream Kinetics M100s (both about 100 wpc).  

Do you think he subwoofer settings will need to be adjusted for each amplifier?  I’m hoping not, but the Elac software should allow that if necessary.

If they are truly the same wattage they will not really need adjusted.
Wattage has nothing to do with it. What matters is the amplifiers' gain. If the two are different, you'll need to reduce the level on the one with higher gain if you want to maintain proper balance. That's one of the common functions of an active crossover.
If they are truly the same wattage they will not really need adjusted. The room greatly dictates the bass. I have a few amps and seem to always end up with the same sub settings.

The EQ for the room no, amps are ruler flat once you set up the room you'll be OK. You may have to slightly adjust the volume.
