other than the OP appears to be an exhibitionist or a braggart, if the management is telling you the neighbor is out of line, then ignore them, or invite them in.
While a person is entitled to reasonably quiet enjoyment, reasonable is not intended to mean you must remain totally silent just because the neighbor has a problem with some noise. Noises from a neighbors apartment is just something one must learn to live with.
Since you seem to enjoy publicizing your activities here, record your sessions and present them to the management as evidence you are not being abusively noisy.
