The Yamaha YUS is often praised for delivering a surprisingly rich and dynamic tone for a 121 cm piano. Yamaha advertised that it “offers Yamaha’s outstanding musical performance and quality, for those who demand the very best sound.” Indeed, the YUS’s tone is characterized by a strong, resonant bass (enhanced by the floating soundboard and X-back frame) and a singing treble with excellent sustain. The mid-range is warm and tonal balance is impeccable; one can play a wide repertoire without feeling the “size limitations” typically associated with 48″ uprights. In essence, the YUS’s sound approaches that of a larger piano. The touch is equally superb – responsive and sensitive, allowing advanced players to execute delicate phrasing and rapid passages with confidence. The action benefits from Yamaha’s premium regulation and possibly slightly longer keys than the standard U1, yielding more leverage. Overall, the YUS feels and sounds like a finely tuned instrument a step above the ordinary studio upright.The Yamaha YUS is often praised for delivering a surprisingly rich and dynamic tone for a 121 cm piano.
