I saw this on Facebook, it’s an article from a 1997 issue of the Piano Technicians Journal. They had two veteran tuners tune two side-by-side pianos, one aurally and one with an ETD, and then had listeners do a blind listening test. I would imagine there are more recent tests like this with more recent technology, but I thought this was a fun read nevertheless. It almost made me wonder if this magazine is still in publication (perhaps online?)
