Wow. This B sounds really crappy. Harsh, shrill, lacking any overtone spectrum that allows tuning it with character. No elasticity, flexibility, resilience in the hammers. Resulting in a bland piano without colors, dynamics and flexibility in creating sounds, especially with una corda as a completely sound changing element of character.
It is surprising to me that you can be so harsh and self assured in your judgement of tone and character based on a recording of a piano you've never really heard in a studio space you've never seen. The university piano professor who has played this instrument for years was quite pleased with the tone and dynamic range with the new hammers.
