We've owned 2 acoustic pianos and this is our first digital piano. We got the rosewood one and what a beautiful finish. But the sound, so rich and full of the Yamaha Grand. We bought during the Covid-19 shut in so we weren't able to listen to in person. I looked at the Kawai KDP 110, Roland 501, Yamaha 144 and 164 and Casio. Ruled out Casio and Roland due to Roland reviews showing various problems, same with Casio. I liked the mellower sound of the Kawai, 5 more voices, and bluetooth. However, there were too many reviews with noisy key action after 6 months to 1 year. Also closest authorized dealer to service is 2 hours away. I chose the Yamaha 164 due to the upgraded amplifier and speakers with 40 watts. I figured the sound would be better even at low volumes, and it's excellent! I don't care about having 10 voices as our purpose is to play piano and improve our piano skills, so though we've tried out the other voices, we keep it on the concert grand. I'm an android person so I was happy to see the Yamaha smart pianist app is on android too, unlike the Kawai. It's easy to maneuver and select voices, etc. I was disappointed that the music conversion feature so hyped in the utube videos only converts to chords, i.e. a minor, b flat, etc, not musical notation. Also the memory is a little lacking. Neither of these would change my mind. This is a beautiful instrument, great action, wonderful tone, love the key cover, pedals are good, though they seems to scratch easy. Oh, and the headphone jacks are a god send, now I can practice at night without disturbing my wife. First time I used them, even with cheap headphones, I had to take them off because I thought they weren't working the sound was so natural and clear. The page stays on the music stand are a nice touch also. The rep at Sam Ash was super helpful and gave me a great deal. The piano was shipped over 1100 miles in 4 business days. It was packaged very well and took about an hour to assemble and was very simple.
