I drank the PRS kool aid, and it was tasty!
There’s something amiss, and I’d look to the nut first. I’m very much a sustain guy, and I wouldn’t put it on the wood combination. Also check the tuners and make sure they haven’t somehow come loose. That’s been known to happen. I mostly play trem guitars, and I don’t believe blocking the trem will make a sustain difference. If the trem block has somehow come loose, that could cause the notes to die. There has to be a loose part somewhere sucking the vibrations. I’d check the tightness of every screw. And if you sort it out, let the factory know.
