Making the Qutest more accessible to mobile-only users with a powerbank friendly power connection then heralding that using any other PSU's void the warranty could be seen as a double standard... so can the (lack of) power switch encouraging people to leave it on 24/7 so we can upgrade again after it croaks.
Oh well look at the bright side, when the Qutest wears out from being left on all year at least we can upgrade to the next succession, and knowing Chord it should honestly be something amazing. At least we can get reliable sonic improvements with aftermarket PSU's on the Qutest even with its' internal step-up switcher - and for that, the Qutest is still a keeper for me.
