I don't k ow if the jack issue was necessarily (or at least unquestionable) fixed with a "second batch". My brother had a supposed "second batch" and his 2.5mm jack was off center and eventually developed a little bit of play. It did co time to work til the day he sold it a few days later. I had one if the I ritual runs from a reseller in Japan. My jack was off center but never become loose. I did sell it however a little while ago. I baby my equipment and he's a little rough with his, don't know if that played a part.
And the distortion with streaming apps was consistent with both of our players.
Onkyo would have to tow back a long way from all these problems to get me on board.
