Hello,
The original Ravenscroft grand piano was developed to quite particular specifications and requirements, allegedly from one jazz pianist especially.
I don't know if the string tension on the Ravenscroft is actually higher than usual, but its sound certainly does make it feel that way. Higher tension, and/or the niche string material (metal alloys) that was used naturally/physically come with shorter sustains. Of course the build of the bridge(s), sound board material and design, all contribute to an instrument's ability to sustain a sound.
An easy example outside the piano realm: a proper double bass plays the same notes as my 34" scale acoustic bass guitar. The string tension is much higher on the upright bass than on my "small" acoustic bass guitar. This (and other factors) makes for a huge difference in sustain. I actually damped/shortened the sustain on my acoustic bass guitar to make it more double bass-like.
Likewise, the Ravenscroft and the Steinway are rather different instruments in their intended use, design, build, and materials used.
Hope this gives you some context,
Cheers!
