## What reviewers say

**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.
