The TC-K770ES was already in the top class at that time and leaves several top decks that are only a few years older, at least sonically clearly behind. However, over the years, a few design weaknesses have emerged, such as the failure of the control for the drive buttons, which caused some K770 to be sent to the e-scrap despite its mint appearance.
