A few Hertz either way in the CW pitch not only doesn't make a lot of psychoacoustical difference, but is hardly perceptible unless you have near-perfect pitch, and even then isn't necessarily a problem. Changing the pitch probably has more to do with the self-resonant frequencies of your speaker enclosures or headphones, and room. Choose a Spot pitch that you like and be done with it. When I was a kid 750 Hz was the most popular sidetone frequency. I have noticed a steady decrease in the consensus spot frequency over these 40 years. I don't know why. Maybe it has to do with hearing loss. Too many 'The Who' concerts. The letter published in QST about this was bordering on junk science. To single out "432 Hz" as some magical sidetone frequency is very like the New Age videos on YouTube claiming that listening to certain magical frequencies can heal your mind and give you holistic peace. It's simply nonsense.
