I got a Mann 2300 and put it on my 2008 SC245. That guitar had the stock bridge with Schroeder locking studs, and it looks like these are the studs used by the OP on this thread.
For starters, the visual appearance was a night and day improvement. As far as tone (keeping in mind I went with a fresh set of strings) things were waaay brighter. Also way more note separation with chords.
The Schroeder bridge studs are noticeably longer than the Manns. Both are brass I believe. So I kept the Mann 2300 but substituted the Schroeder studs and things were right back in the tonal ballpark that I like. Sustain was also much better with the Schroeder studs...they’re not “pretty” like the Mann studs but my ears won out.
Being longer, I can’t screw the Schroeder studs down to my preferred action height, so I assume they’re bottoming out and I’ll need to deepen the cavity and maybe use the longer Schroeder bushings which I never installed. They’re brass, if the PRS bushings are not also brass then tone will certainly change. Does anyone know the material of the PRS bushings?
There’s also the issue of the ground wire, so I might get a local luthier to help with this minor surgery!
Bottom Line: I like the Mann bridge! Sounded better to me with the Schroeder studs but looked better with the Mann studs.
I found the 2300 to be perfectly intonated with no adjustments. When I can drop the string height just a half turn it should be perfect.
