Those are just the subjective differences. There are many others that
are objective and less tangible, but very important nontheless.
Designers of tuner circutry usually don't give a hoot about audio quality
because the signal being recieved is prettly low fidelity anyway, so why
pass it through an expensive high quality audio stage? Things like
dynamics, timbral acuracy, midrange bloom, treble purity, bass punch,
etc. Measurements are one thing, but objective performance, untouchable
by measurments, are what we actually hear.
