“Ruben’s playing is not only professionally accomplished, but always intelligent and interesting... Brought up in the traditions of the Russian Piano School, he combines the unique features in the field of subtle interpretation and beauty of sound... In his performances I always hear something new to me, and not only new, but consistently interesting.”

- Lazar Berman

“Ruben is endowed with all the qualities necessary for the pianist of today: an imaginative command of the sonorities of his instrument, the ability to craft his playing to the whole range of styles within the repertoire and a brilliant technique. However, it is his total commitment to the works he performs that endears him to audiences.”
- Yuri Paterson-Olenich, England

“…The level of Dalibaltayan’s mastery puts us in mind of some forgotten traditions of Russian pianism. Ruben Dalibaltayan, a pupil of Valery Kastelsky, inherited the great achievements of Neuhaus’s school. In his own work, Dalibaltayan achieves a revival of the richness and splendor typical of the representatives of the great teacher's tradition…
…Ruben Dalibaltayan’s proficiency has many characteristics unique to the Russian piano school, such as a culture of a stylistic approach, technical finesse and an austerity in his artistic taste.”
-  Svetlana Sarkisian, Professor of State Yerevan Conservatory
