The new generation is level on paper

Both makers replaced their mid-range home consoles within a year. Kawai's global site now lists the CX202 as the current model in place of the KDP-120, and Yamaha Japan marks the YDP-165 as discontinued since the YDP-166 arrived in June 2026. When the older pair was the comparison, Bluetooth was a large part of the decision: the YDP-165 had no Bluetooth at all, and the KDP-120 offered Bluetooth MIDI only.

That gap is gone. The CX202 and the YDP-166 now match on a surprising share of the spec sheet: 88 keys, 192-note polyphony, 40 W of amplification through two 12 cm speakers, Bluetooth audio and Bluetooth MIDI, two headphone jacks, three pedals and a sliding key cover. Neither has a line output.

So the choice rests on fewer points than it used to: the key action, the sound source, the headphone sockets, size and weight, and what comes in the box.

A note on method: this is a spec-based comparison. We have not played the two side by side, so instead of ruling on feel we set out what each maker publishes.

Key action: each spec sheet states something the other does not

The CX202 uses Kawai's Responsive Hammer Compact II. In Japan Kawai sells the same keyboard under the name Grand Emotional Action Standard (GES), so a different name on a Japanese listing does not mean a different action. The hammers are graded, heavier in the bass and lighter in the treble. Kawai's international specification lists a triple sensor, and the keytops have a matte finish.

The YDP-166 uses GrandTouch-E, a keyboard Yamaha developed for this ARIUS generation. Its specification lists escapement, the slight notch a grand piano gives near the bottom of a very soft keystroke, and synthetic ebony and ivory keytops. Yamaha does not publish key weights or a sensor count for it.

So Kawai states a triple sensor and Yamaha states escapement. Neither sheet tells you how the keys respond under the fingers. On our own spec-derived touch scale, GrandTouch-E sits one step above RHC II. That grade comes from published construction, not from playing them, and one step is not a gulf.

The difference in keytop finish is something you can check in a shop within seconds. If you can try both, this is the section to settle with your own hands.

Sound: two concert grands, not two quality levels

The CX202's piano sound is based on the Shigeru Kawai SK-EX concert grand, reproduced with Harmonic Imaging and damper resonance. It has 17 sounds and six reverb types. The YDP-166 uses the Yamaha CFX concert grand sample with VRM Lite resonance, 10 voices and four reverb types.

Each maker starts from its own flagship concert grand, so the difference is one of character rather than tier, and character is not something a spec table can describe. The Kawai's seven extra sounds matter little to a household that mostly practises piano. Anyone who wants many electric piano or organ variations will find both limited.

Speakers: the same output, handled differently

Both put 20 W × 2 through two 12 cm speakers. Neither will sound obviously louder in a living room.

What differs is around that output. Yamaha fitted diffuser grilles in front of the YDP-166's speakers, which it says spread the upper range more evenly through the room; that changes dispersion, not level. For quiet playing, Kawai offers Low Volume Balance and Yamaha offers Intelligent Acoustic Control, both of which adjust the tone when the volume is turned down. The speakers are not the tie-breaker in this pair.

Headphones and Bluetooth

Both have two headphone jacks and headphone processing (Spatial Headphone Sound with a headphone type setting on the Kawai, Stereophonic Optimizer on the Yamaha), so two people can practise quietly on either.

The practical difference is the sockets. The YDP-166 has two 6.3 mm jacks; the CX202 has one 6.3 mm and one 3.5 mm. Headphones with a 6.3 mm plug go into either. If the second listener uses earbuds or small headphones with a 3.5 mm plug, the Kawai takes them without an adapter.

Both support Bluetooth audio, so a phone or tablet can play backing tracks or lesson videos through the piano's speakers, and Bluetooth MIDI for apps: PianoRemote on the Kawai, Smart Pianist on the Yamaha. One caution applies to the Yamaha only. Its US specification marks Bluetooth as varying by area, so confirm with the dealer that the unit sold in your country has it. Yamaha's Japanese specification lists Bluetooth without that note.

Neither has a line output. The YDP-166 can work as a USB audio interface over USB TO HOST, which is the route to a computer or a recording setup.

Both have a lesson function with a song library: 296 built-in songs are listed for the CX202, and 303 lesson songs plus 50 piano classics for the YDP-166.

Size, weight and what comes in the box

The footprints are close. The CX202 measures 1,365 × 405 × 855 mm and the YDP-166 1,357 × 422 × 849 mm. The Kawai is 17 mm shallower, and width and height differ by less than a centimetre. Weight separates them more: 37 kg against 42 kg. Neither is furniture you move often, but five kilograms is noticeable on stairs or when one person repositions the piano.

Included accessories depend on the market, and this is where listings are easy to misread. In Japan the CX202 comes with a fixed bench and SH-2N headphones, and the YDP-166 with a height-adjustable bench and headphones; an adjustable bench helps when a child and an adult share the piano. Outside Japan, Kawai's global page lists a WB-10 bench and no headphones, while Yamaha's US page marks the bench as area-dependent. Check the dealer's listing before comparing offers.

Which one fits

Choose the Kawai CX202 if a cabinet that is five kilograms lighter and slightly shallower, a 3.5 mm jack for earbuds and seven more sounds matter to you, or if the character of the SK-EX appeals.

Choose the Yamaha YDP-166 if you want escapement and ebony and ivory keytops written into the specification, prefer the CFX sound, or want two full-size headphone jacks. Confirm Bluetooth on the regional version before buying.

With Bluetooth, polyphony and speaker output now level, this pair is closer than the previous one. The deciding points are the key action and the character of the sound, and both are best judged with your own hands. If that is not possible, the practical details (weight, headphone sockets, the bench in the box) are enough to decide on.

If you want a higher-grade action, a line output or many more sounds, the better comparison is Kawai's CA series or Yamaha's Clavinova range rather than a choice between these two. For remaining stock of the older Yamaha, see our Kawai CN-201 vs Yamaha YDP-165 comparison.
