As the reviewed gear measures different isn't it quite expectable that there are also hearable differences?
No. If two pieces of equipment measure differently, but the differences are well below any reasonable audible threshold, there's no reason that they can sound different. For example, if DAC A has 0.004% distortion and DAC B has 0.0004% distortion, then
ceteris paribus they will not sound different even though the measurements differ by a factor of ten.
We can measure FAR more precisely than our ears can distinguish.
