Atc scm20 passive

Has anyone here tried bi amping a Atc scm 20 ? I think it might 

be overkill, but I’m just curious . I have a couple of new Parasound A21+ 

and I could try to bi-amp. I’m sure with 300 watts per speaker the bass is not 

strangling the tweeters of any power, but sonically was curious . Thank you
