Pioneer M-90 Amp

Is the Pioneer M-90 amp common ground?

I did some research but did not get a definitive answer.

Thanks

As far as I remember it is indeed Common Ground. A beast of an amp.

Thanks I did alittle more research and it will work
When I get it I will test it against my Adcom 545, I dont think it will take the place of the Adcom.
It was kinda part of a package deal
