Streinway "Accelerated action".

[Phil Ryan]

I was talking to a very influential piano teacher in the area and she
insisted that the reason V. Horowitz was able to play so rapidly was that
his piano was adjusted to increase the repetition speed.  I responded that
if that was possible to do without sacrificing other control aspects,
Steinway and other piano manufacturers would all do it.  I've read "My Life
with the Great Pianist" and see nothing in there were Horowitz's piano was
"juiced."  Am I correct?  Does anyone have any inside info?
