Sorry Gustavo, i own A4 since one month and S&H was already there…i kind of remember a video(?) that was displaying TUN and i could hear the hi-freqs attenuation moving that knob…but maybe it was just my imagination when i was reading manual prior to decide to buy the A4 
Anyway,i am for having this digidigidigidiggital-sounding S&H parameter but, at least, the TUN too
Thanks for the reply…i was actually looking for
…they change it’s name silently to S&H
