The question NU1XA or Novus NV6 comes up for anyone wanting a tuning-stable, volume-adjustable piano without giving up the feel of a real piano action. Both belong to the hybrid piano class: they carry a real upright action with wooden keys and hammers, but no strings. Instead of striking a string, sensors read the hammer movement and the sound is generated digitally.
That makes a hybrid different from a silent piano. A silent piano has strings that are simply muted by a stop bar. A hybrid like the NU1XA or NV6 has no strings and no soundboard at all. This article compares the two compact upright hybrids: action, sound generation, format and price tier.
Compact piano hybrid with a real upright action and wooden keys
Ideal for: Ideal for anyone after a slim, living-room-friendly hybrid with the familiar Yamaha sound

Ideal for: Ideal for players who value the Kawai action and a particularly fine touch
See all Digitalpianos →01What defines an upright hybrid
An upright hybrid takes over the full playing action of an acoustic piano: wooden keys, hammer head, repetition. What is missing are the strings and soundboard. Each hammer movement is captured by sensors and translated into a digitally generated sound, played back through a built-in speaker system or headphones.
The advantage over a pure digital piano is the touch: the action responds like a real piano, including trills and fast repetition. The advantage over an acoustic piano is practical: tuning-stable, volume-adjustable, playable at night through headphones and less sensitive to room climate. Both models here share this principle but solve it differently in engineering terms.
02Action and sensing compared
The Yamaha NU1XA AvantGrand Hybrid Piano – inkl. Lieferung & Aufbau uses a specialised upright piano action with real wooden keys. Yamaha captures the touch through a non-contact electromagnetic sensor system that reads both the key and the hammer movement for each note. Because the sensing is contactless, there is no mechanical wear at the measuring point.
The Kawai Novus NV6 Hybrid Piano schwarz poliert – inkl. Lieferung & Aufbau relies on the Millennium III Hybrid action, derived from Kawai s K series. It uses individually weighted ABS Carbon hammers and even keeps a real damper mechanism, even though there are no strings to damp. Hammer movement is measured with high-resolution optical sensors. Both approaches deliver very precise touch detection but start from different action philosophies.

| Strings | none | none |

03Sound and format in daily use
On sound, each follows its house philosophy: Yamaha works mainly with sampling and gives the NU1XA a speaker system radiating to the front and back to recreate the fullness of a grand. Kawai bases the NV6 on the rendering of a concert grand. Which approach you prefer is a matter of taste and best settled by playing them side by side.
In format, both are deliberately compact and fit into normal living rooms, where an acoustic piano with a soundboard demands more space and care. Both are tuning-stable and volume-adjustable down to headphone use. To compare the full hybrid range, see our category Digitalpianos.
04Price tier and recommendation
The two models are not on exactly the same level: the NU1XA is the entry into the Yamaha hybrid class and is priced notably lower, while the Novus NV6 sits in the higher hybrid tier and costs more accordingly. If you mainly want a slim, everyday hybrid with the familiar Yamaha character, the NU1XA is a good fit. If you put the Kawai action and a particularly graded touch first and plan for the higher budget, the NV6 is the one.
If you are still weighing up whether a hybrid is right at all, our article on the hybrid piano principle sets the ground. We cover the larger sibling in the Kawai Novus NV6 spotlight, and present the Yamaha hybrid in detail in the NU1XA article.
NU1XA or Novus NV6 ultimately comes down to a choice between two action philosophies and two budgets. Both deliver real piano playing without tuning, without strings and in a compact format. Once you have played both side by side, the touch that is yours becomes clear quickly.
