Eighty-eight keys, and what they weigh · review
A console piano rather than a portable one: 88 Graded Hammer Standard keys, three pedals and a cabinet that stays where you put it. Yamaha also fits a volume limiter, which sets a ceiling on output.
What it amounts to The right answer when the piano has a permanent home — and the wrong one if it ever has to be carried.
The ARIUS YDP-105 is the console option in this group, and that single fact drives everything else. The stand is the instrument, the three pedals are part of the cabinet, and nothing shifts under the hands during a loud passage.
The action is Yamaha’s Graded Hammer Standard: heavier in the bass, lighter in the treble, the way an acoustic piano behaves because of the physical size of its hammers. Yamaha also lists damper resonance modeling, which is what makes the sustain pedal do something more interesting than simply holding notes.
The volume limiter is worth naming because it is unusual on an instrument at this level. Yamaha describes it as a ceiling for output through the speakers or headphones. That is the manufacturer’s description, and this site reports it as such and stops there.
Two practical notes from the price data. There was no US offer when this page was written, and the Spanish price stood well above the German one — enough that it is worth checking your own store before ordering.

Yamaha describes it as a way to define a maximum volume through the speakers or headphones. We report the feature as the manufacturer states it and give no advice about listening levels.
No. The P series is portable and takes a separate stand and pedal; the ARIUS YDP line is a console instrument with the stand and three pedals built in.

88 touch-sensitive keys · 480 sounds · full accessory bundle

Best for: A first instrument for someone who is not yet sure they will keep playing.
≈ $190
88 weighted keys · 10 sounds · pedal and stand included
A slim 88-key board with Casio’s Scaled Hammer Action II and, unusually at this price, the SP-3 pedal, music rest and power adapter already in the box. Ten sounds rather than hundreds — the money went into the keys.
Best for: A first weighted piano where the pedal and adapter should not be a second order.
≈ $820
88 keys with touch response · 13 hours on batteries · 23.1 lb · stand and bench in the bundle
A bundle rather than an instrument alone: the CDP-S160 with a stand, a bench, a pedal, a music stand, an adapter and headphones — and the only piano here to publish a battery life and a weight.
Best for: A first piano that has to arrive complete, stand and bench included, and be carried occasionally.
