Kawai Novus NV10Schat_bubble_outlineFrom real comments

The action is the standout feature owners keep coming back to. Multiple commenters say the NV10S has an action nearly identical to a real grand piano, with one saying no other digital piano has matched it. A shop visit comment notes that the price is largely driven by this best-in-industry hybrid action rather than the soundboard, reinforcing that touch feel is the instrument's core selling point for serious and amateur pianists alike.

Built-in speaker sound quality is a recurring disappointment. One owner who bought the NV10S four months prior said the speaker sound was disappointing, describing it as coming from 'a deep, distant well' with some notes too metallic and others dull, calling it far from a real grand piano. Another commenter found the tone tinny even through excellent headphones, though they note this could be subjective or setting-dependent.

Sound customization and soundboard tradeoffs raise questions. A commenter points out there's no real equalizer, only presets, limiting tonal adjustment. Another wonders how the NV10S's lack of a soundboard compares to the NV5S in terms of sound impact, suggesting uncertainty among buyers about whether the flagship model's tone justifies skipping that acoustic element found in cheaper siblings.
