The binaural recording, regarless of its other qualities, has a significant additional clarity compared to the 'stereo' recording. I am enjoying it more because of this than the 'stereo' recording on the same cd. To my ears/mind, it is closer to what I imagine it should be (IMHO, IMHO, IMHO) 'in the case of Gould'.
His 82 recording is so different from the 55 (or the 59th Salzbourg live), that we cannot really assume that the recording/piano sound that he achieved in 82 was the one to look for in a reperformance of 55. Still, he has been consistant his whole life regarding his Piano, how it should feel (key weight and course length) and sound.
Actually, this is interesting for everybody to see the impact of the recording. We rarely have have this opportunity. We have remasters, but rarely an other recording of the same performance. This is helped here by the fact that his 55 performance was pretty fast conpared to the 82 one (so the 2 recordings fits one cd).
The booklet notes indicates that the 'stero' and the binaural recordings, have been performed at the same time, on the same 'reperformance'.
Interesting indeed is the mix of enjoyment and frustration.
For example, if I listen to the complete goldbergs (and not only picking a single variations), I feel more that something is missing.
