Casio AP420 Reviews
Pro: Build and mat finish
Cost to benefit ratio
Classic styling with out too fussy digital interface
Still has MIDI support (through USB)
Comes with metal 3 pedals (half step supported).. (didn’t realize that most of the time you use only one but looks nicer)
Con: Sampling is not as good as a Yamaha, as it resamples based on a smaller sample set, the rest are interpolated. Higher end Yamaha’s sample every key
Hitting of keys hard make an audible sound (headphones or increased volume eilmliate this)
When on full volume playing a single key you can hear when the note actually ‘ends’ which is a little staticy (this is not how you play a piano)
A few too little voices, but fine as a ‘piano’

Yamaha YDP141 and Casio AP420 are OK for beginners.
They both have a nice piano sound and an even touch.
There’s two main advantages the Casio AP420 has
over the Yamaha YDP141:
1) The Casio AP420 has an ‘ivory feel’ touch. This
feels a little more silky under the fingers. It’s
quite a nice feeling actually.
2) The AP420 has more powerful speakers (2 x 20 watts
versus Yamaha’s 2 x 6 watts). The bigger speakers
give you more power. But it’s not only the volume
level that improves; the bigger speaker wattage
adds richness and depth to the piano’s tone.
And there’s two main advantages the Yamaha YDP141
has over the Casio AP420:
1) The Yamaha YDP141 has a higher build quality.
It’s also more reliable (understandably), thus
less likely to break down.
2) The Yamaha YDP141 has a higher resale value than
the Casio AP420 (about £50 – £100 difference).
… Yamaha pianos command a higher price on the
second hand market than any other brand.
Now the choice…
It’s a close call between the two, but the slightly
smoother feel to the keys, and the richer, fuller
sound give the Casio AP420 the edge over the
Thank you for the wonderful piano guide. It has helped me weigh in what is possible to buy taking in to consideration my desire to continue to grow and play demanding works on the piano, and the limits of my budget.
Because of your guide, I have narrowed it down to the Yamaha Arius YDP 141 and the Casio AP 420. I understand that the casio is a little better, keyboard and sound-wise while the 141 has a better resale value.
I would like to know, what aspect of the Casio AP 420’s keyboard is better than the YDP 141? I know the 141 is medium weighted, and graded hammer standard. The casio is graded hammer standard but is it also medium-weighted? I would like to pursue challenging pieces from listzt and rachmaninoff so i need the best possible for the price range.
Thank you very much,

If you intend playing such challenging pieces
I think you will struggle on these basic pianos.
But I understand you have a limited budget.
Both the Casio AP420 and Yamaha YDP141
score exactly the same on the Howard Score
digital piano rating system. But if I were
pressed to choose between them, I would go
for the Casio because it has slightly more
resistance on the key touch.
Another piano I would like to recommend
for you is the Broadway B1.
The Broadway has a nicer, more authentic
key touch. The weighting is better, and it has
more resistance on the down stroke. You can
feel and control the keys much better when
playing more demanding pieces.
Overall it is a better piano then the Casio AP420
and Yamaha YDP141.
