Our Verdict
The Novus NV-10S contains an actual Millennium III grand piano action — the same mechanism found in Kawai's acoustic concert grands — paired with a 200W Onkyo 8-speaker system and SK-EX Rendering sound engine. This is as close to acoustic as digital gets.
Pros
- • Millennium III grand piano action — the actual mechanical action from Kawai's acoustic grand pianos, not a replica or simulation
- • 200W 8-speaker Onkyo-tuned system — the most powerful amplification in any Kawai hybrid, projecting sound with concert-hall presence
- • SK-EX Rendering sound engine captures every nuance of the Shigeru Kawai 9-foot concert grand
- • Grand Feel III wooden keys with counterweights — connected to the real Millennium III mechanism above
- • Silent practice with authentic touch — turn off speakers and the mechanical action still gives you full acoustic key feel through headphones
- • Bluetooth Audio + MIDI with PianoRemote app integration
- • Premium polished ebony cabinet — an instrument that commands the room visually and acoustically
Cons
- • 115 kg — this is heavier than many acoustic uprights; professional delivery and floor reinforcement considerations are essential
- • $10,000 buys a quality acoustic grand — you must specifically want the hybrid advantages (silent mode, digital features) to justify this
- • 609mm depth is substantial — requires dedicated space planning, not a casual furniture addition
- • Mechanical action noise is present even in headphone mode — the hammers physically move, producing faint but audible keybed sounds
- • No line-out jacks — an inexplicable omission at this price tier
The NV-10S is not a digital piano with good touch — it's an acoustic piano action with digital sound generation. That distinction matters enormously. At $10,000, it competes with entry-level acoustic grands, and the decision comes down to what you value more: the resonance and projection of real strings, or the ability to practice silently, connect via Bluetooth, and never call a tuner. For pianists in apartments, those with noise-sensitive neighbors, or anyone who practices late at night, the NV-10S is genuinely the only instrument that doesn't require compromising on touch. Compared to the NV-5S ($7,500), the NV-10S adds the full Millennium III action (versus a modified version), 200W speakers, and a grander cabinet. If touch authenticity is your absolute top priority, this is the endgame.
Technical Deep Dive
About the Key Action
The NV-10S doesn't simulate a grand piano action — it contains one. The Millennium III action is the same mechanism installed in Kawai's GX and SK series acoustic grands. Real wooden hammers pivot on a real center pin, traveling through a real repetition lever with genuine let-off and escapement. When you press a key, you feel the exact same mechanical chain of events as on a $50,000 Shigeru Kawai SK-5. The only difference is that instead of striking a string, the hammer triggers an optical sensor. For any pianist who has spent serious time on acoustic instruments, the distinction between this and even the best purely digital action is immediately and unmistakably clear.
Who Is This Piano For?
You're a concert-level pianist or a dedicated advanced player who has spent decades on acoustic grands. You know the exact feeling of a Kawai grand action — the weight, the escapement, the way a key rebounds after a staccato — and you're not willing to accept any substitute. But you live in an apartment, or you practice at midnight, or you simply want zero maintenance. The NV-10S is the only digital piano that gives you an actual grand piano action with the ability to turn the volume to zero.
