The question behind the search

If you are weighing the Kawai CA-401 against the Yamaha CLP-845, you have already narrowed the field to serious furniture consoles — full-size cabinets with a fixed stand and a three-pedal unit, meant to sit in one room for years. Neither is an entry instrument. The useful question is not which brand is better in the abstract, but which of two different design choices matches the way you will actually play.

There is a price gap here, and it is not small: the CLP-845 is the pricier of the two. What that step-up money buys — and whether your playing needs it — is the whole comparison.

A note on method: this is a spec-based comparison. We have not sat down and played these two consoles back to back, so instead of claiming a winner on feel, we line up what each maker actually built and match it to who benefits.

Key action: two families, both weighted

The touch is where these pianos diverge first. The CA-401 uses Kawai's Grand Feel Compact action, a weighted hammer mechanism with a counterweight in every key and an ivory-feel key surface. The CLP-845 uses Yamaha's GrandTouch action, also weighted, also with an ivory-feel surface. Both are graded — heavier in the bass, lighter in the treble — and both are a clear step above the plastic actions in cheaper consoles.

What they are not, on either side, is wood-keyed. Both use synthetic ivory-feel surfaces; genuine wooden key tops arrive only one tier up, in the CA-701 and CLP-875. If a wooden-key action is a hard requirement for you, neither of these is the model — that is a reason to price the next step up rather than choose between these two.

Grand Feel Compact and GrandTouch feel different because they are engineered around different acoustic references, and "better" here is a matter of which touch you prefer. The honest framing for a shopper is: try both if you can, because this is the one difference a spec sheet cannot settle for you.

Sound engine: one concert grand vs two

The CA-401 is built on Kawai's SK-EX Rendering, modeled on the Shigeru Kawai SK-EX concert grand, and it carries 19 voices. The CLP-845 runs Yamaha's dual-flagship sound — CFX and Bösendorfer Imperial — with VRM string-resonance modeling, and 38 voices in total.

For a pianist, the number 19 versus 38 matters less than the character. The CA-401 gives you one deeply modeled Kawai concert grand and a focused set of supporting tones. The CLP-845 gives you two distinct concert-grand personalities — the bright, projecting CFX and the darker, deeper Bösendorfer — plus a wider bench of electric pianos, organs, and strings. If you like switching between two grand-piano voices for different repertoire, that flexibility is real. If you play one piano sound almost exclusively, the CA-401 gives up very little.

The room: speakers and cabinet

This is where the price gap becomes audible. The CA-401 drives a 100-watt, 4-speaker system; the CLP-845 steps up to 142 watts across 6 speakers. Played out loud in a living room, the six-speaker Yamaha has more headroom and a wider spread, which matters most in a larger space or when you want the instrument to fill the room.

The cabinets scale with the sound. The CA-401 weighs 56 kg; the CLP-845 is a substantially larger 72 kg and taller. Both are furniture you place once and leave, but the Kawai is the easier one to fit into a compact room and the lighter one to position. For classical practice under headphones, where the speaker system barely comes into play, this whole section matters far less — which points squarely at who each piano is for.

Where they draw even

Much of the spec sheet is shared. Both offer 256-note polyphony, enough for dense pedaled passages in Romantic repertoire. Both include Bluetooth Audio and Bluetooth MIDI, USB MIDI, and app connectivity. Both have two headphone jacks with headphone optimization for quiet practice, and both ship with the stand and a damper pedal included. Neither has a line out, which is worth knowing if you plan to record to external gear. The CLP-845 does carry more built-in practice songs (303 vs 176), a modest edge for lesson-style learning.

Who should buy which

Buy the Kawai CA-401 if you want the most piano-focused instrument for the money, practice largely under headphones or in a smaller room, prefer a lighter and more compact cabinet, and are happy with one well-modeled Kawai concert-grand voice. It is the value pick in this pair without feeling like a compromise on touch.

Buy the Yamaha CLP-845 if you play out loud in a larger room and want the bigger 6-speaker sound, value having two contrasting concert-grand voices and a broader tone set, and don't mind paying and housing more for it. It is the step-up console, and the extra money goes into sound projection and voice variety rather than into the key surface — which stays ivory-feel on both.

The deciding question is simple: are you buying for the headphones or for the room? Answer that, and the CA-401-vs-CLP-845 choice mostly answers itself.
