SONY Sonahawk ZS-66 vs. ZS-70 - Some different features, a little bit different sound

A short comparison between SONY’s ZS-66, Made in Japan (1992/93), and its successor ZS-70, Made in Korea (1993/94). Main feature difference is a motorized stand on ZS-66 that can be remote controlled, as seen in video. Beside this there are different illuminations of operation buttons, an LED on ZS-66 showing remote signal receiving and an additional optical digital out on ZS-70. ZS-70 seems to have a stronger bass, maybe because speaker edges were allready replaced. Both are completely repaired and fully working.
