Yamaha YUS5SH vs YUS5SH2 vs YUS5SH3

Hi there
I’m building this page to store info about Yamaha’s YUS5SH line of pianos

So far, I think the following list is broadly accurate but please tell me if I’m wrong:

• YUS5SH – mid-2000s introduction (Silent SH system)

• YUS5SH2 – 2018 update with SH2 silent system

• YUS5SH3 – around 2021–2022 with SH3 system (Bluetooth, new sensors)
