Cone denim is nice, but feels a bit basic to me. Comparing it to something like say, Sugar Cane Okinawa, there's just no comparison. Japanese denim always felt better, and I'm sad they're departing from it.
While I'm not going to deny the sonic superiority of p2p amps, I don't think this is the reason. Pcb circuits use shorter traces overall. I'm in the middle of handwiring a tweed deluxe myself. It may be how the signal paths overlap too much on a circuit board that alters tone, or how two components are directly connected in p2p, but are connected by an intermediate trace on pcb that alters tone.
