1 degree phase error at 14 kHz corresponds to 0.067 mm at the speed of sound. Are your pinnae that stable ? Since the UHJ coding / decoding is not particularly ill-conditioned, which means errors are not amplified by any significant amount, I'd say that considering this kind of precision is really over the top.
