What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Yamaha P-225
Only one whitelisted tester (MusicRadar) published a hands-on review of the exact P-225; no Sound on Sound coverage was found. MusicRadar praises the restored USB audio, CFX grand sound and compact GHC action, but flags hard-to-reach rear ports, a higher price, and an action that is 'no backward step' yet no big leap over the P-125a's GHS. (1 sourced review.)
Praised: Restored USB audio recording, fixing the P-125a's omission, plus Bluetooth audio streaming; Yamaha CFX grand piano sound with VRM Lite sympathetic resonance modelling; Compact GHC weighted action stays convincing and satisfying to play; matte keys grip well.
Flagged: Rear connection ports sit in a deep recess that is very hard to reach when set up; More expensive than the P-125a it replaces; New GHC action is no meaningful step forward over the outgoing GHS.
