    What reviewers say

    Yamaha CSP-275 Clavinova Smart Digital Piano

    Owners of the CSP-200 series generally praise the piano sound and the guided-learning features, and reviewers treat the wooden GrandTouch-S action as a clear step up from entry Clavinovas. The most common complaints concern size, weight, and the app dependency for the smart features.

    Pros
    • Authentic grand piano tone from the CFX and Bösendorfer samples
    • Stream Lights make learning new pieces faster
    • Wooden key feel close to an acoustic grand
    • Smart Pianist app is intuitive for settings and practice
    Cons
    • Heavy and hard to move once assembled
    • Some features require the app and a connected device
    • Price is high compared with slab pianos
    • Speaker sound can feel boxy in small rooms

    Yamaha Clavinova CSP-170 Home Digital Piano Polished Ebony With Bench

    Owners generally rate the CSP-170 highly for its keyboard feel and grand piano sound, and the Stream Lights learning system gets frequent praise from beginners and returning players. The main complaints are the tablet dependency and the app's reliability over time.

    Pros
    • Natural wood key action feels expressive and close to an acoustic
    • CFX and Bösendorfer voices sound rich through headphones and speakers
    • Stream Lights make practice structured and fun
    • Sturdy cabinet and bench suit a living room
    Cons

    • Heavy and awkward to move
    • Limited wireless connectivity

    Questions and answers

    Which is better for a beginner learning songs?
    Both have Stream Lights and Audio To Score. The CSP-275 adds Bluetooth MIDI, so the Smart Pianist app connects without a cable, which is easier for beginners.
    Do they sound the same?
    Both use Yamaha CFX and Bösendorfer Imperial samples with Virtual Resonance Modeling and binaural sampling. The CSP-275 adds Grand Expression Modeling and a stronger amplifier and speaker system.
    Which has the better keyboard?
    The CSP-275 uses the GrandTouch-S action with wooden white keys. The CSP-170 uses the older NWX wooden keyboard. Both have escapement, but the CSP-275 is the newer design.
    Is the CSP-275 worth the extra money?
    If you want Bluetooth MIDI, wooden keys and more power, yes. If you mainly play through the speakers and use a cable for the app, the CSP-170 covers the basics for less.
    Can I move either one alone?
    The CSP-275 weighs 133 kg (293 lb), so plan on two people and a dolly. The CSP-170 is also a cabinet piano and should be moved the same way.
    Which lasts longer?
    Both are cabinet Clavinovas built to last many years. The CSP-275 is the newer model, so it will likely get firmware and app support longer.
