The Kawai Novus NV10 features the same action and pedal mechanism as Kawai's grand pianos, providing a realistic feel not commonly found under $15,000.

The Kawai K300 with the AURES system allows for MIDI output, enabling usage with digital sheet music, apps, and recording, enhancing its versatility.

The Kawai CA-901 model includes a soundboard for an enhanced native sound experience, whereas the CA-701 lacks this feature but is ideal for headphone use.

The CA-401 model provides a premium digital action with the SK-EX Competition sound set, offering an advanced experience close to higher-end models.

The Yamaha AvantGrand N3 is noted for having better stability with its three legs, potentially reducing shaking compared to the NV10 during spirited playing.

Within Kawai's lineup, the Novus NV5s is noted as the closest experience to an acoustic instrument, but at a high price point.

Shigeru Kawai pianos are considered closer to Steinway's quality, but some owners feel they lack the power of Steinway grands over 1.80 meters.

It's noted that Steinways under 1.80 meters can be noisy, whereas Kawai and Yamaha are recommended for smaller grand pianos.

Kawai pianos reportedly have a warmer sound profile compared to Yamaha's brighter tone, which might appeal to those seeking a softer sound.

In silent mode, Kawai pianos produce a harder rebound and a slight knocking sound as hammers hit a rail instead of strings, differing from the acoustic experience.

The MP11SE is praised for its unparalleled action, though some owners desire a more tactile feel for genres like baroque and rock, indicating personal preference in touch.

Shigeru Kawai owners highlight the action as excellent and note significant cost savings compared to Steinway, with prices around 60% less for new models.

Some users experience Kawai pianos going out of tune quickly in higher notes, potentially due to climate conditions not suited for the instrument.

The ES520 is highlighted as offering exceptional sound and playability in its price range, often outperforming other digital pianos in-store.

Shigeru Kawai is often preferred over older Steinways due to better condition at similar price points, emphasizing a balance between age and performance.

Kawai pianos use plastic parts within the action, reportedly to prevent degradation over time and resist climate effects, which is a point of contention among users.
