2 Powernode/ Bi-Amping

Hey You longtime Users, I know this topic was interesting for some Users before me. Has anyone ever tried to use 2 Powernodes as Monoblocks ? Of yes, does it improve the Soundquality to a next Level ? Actually i "only" own a pair of 2017's Teufel Ultima 40 MK2, so not one of the best Speakers on the Market. Bit they have a Bi-Amp Terminal. Thx for some Answers Gordon
