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.
