Thanks @Torq. It was very nice of both Schiit and SPL indeed.
I agree with all your points and I definitely don’t want to fry another costly amp and I’m sure that SPL wouldn’t be só understanding this time around. I tried them in bridge mode anyways and man, the improvements were not night & day (maybe 5-10% max) but the bottom end just got more heft and the overall sound got more body to it.
I won’t rely on the protection systems because they failed to trigger last time “I needed” them to work. Thus, I’ll run a single Performer s800 with the SR1a and the other one on my speakers rig.
