Good observes (p. 201):  "the tone, especially in the bass, is open, has relatively strong higher partials than a Steinway would have, and gives a somewhat distinct, though not hard, sound."
The passage from Good (page 201) discusses the unique tonal qualities of an instrument, specifically highlighting its open tone in the bass range and the presence of stronger higher overtones compared to a Steinway piano. This results in a distinctive yet not harsh sound.
