what does that mean?


It means that your amps may actually be causing the damage to the 975 by causing transients/brownouts/noise etc. that get back on the power lines feeding the 975.

Note that although the Furman has two outlets you're still limited to the 20A limit of your circuit. i.e. you can't get 20Amps out of both outlets at the same time.

I'd feel more comfortable if there were on two circuits so you could split the load.
