When we look at the 5'3" (160cm) grand piano market, the Ritmüller GH160R and the Kawai GL-20 offer a fascinating contrast between high-tech innovation and old-world craftsmanship. While Kawai is renowned for its Millennium III carbon-fiber action and clean, modern precision, the Ritmüller GH160R designed by German master Lothar Thomma—focuses on a "boutique" European soul.
