I don't understand why some of you can't answer the simple question of the OP without sarcasm; I can't find any of the suggested metaphysical implications in his question. You can just say you did it and liked it or did it and didn't liked it, and maybe explain why that was so for you.
I join the part of answers saying that it sounds well on some instruments and not so well on others. My main problem with changing the pitch slightly is that my tonal orientation gets a bit confused or disoriented, so I rather prefer to stick to 440 even if I actually preferred 432 or whatever other pitch it might be.
As player of transposing instruments too I then rather sometimes like to go to 415 HZ pitch which is equivalent to tuning down a semi-tone (well actually it would be 415.3 for A). Some guitars get really a quite different character and also the mood is different (whatever people might put into it philosophically).
Music is a big continent with different landscapes and corners. Some of them I do visit frequently, some from time to time and some I know from hearsay only ...
