Also.... have you had issues with the headphone jack in Dave failing? That final push to lock In place sees to require more force than usual.
I had a headphone that worked fine out of either 1/4 jack on the TT2, but it would not work out of my Dave, lots of distortion. My other headphone worked out of TT2 and Dave fine. I replaced the formers original cable with a third party cable, and all was fine. I have one caveat though in as much that I cannot physically insert the jack into Dave, so rely on others to do it for me. I’ve had this distortion happen just a couple of times recently, and in each case taking the jack out and pushing firmly back in has resolved the issue. The original cable that wouldn’t work out of Dave though was definitely pushed home firmly, several times, so am convinced it was a problem with Dave, with that particular jack, even though it never gave a problem with TT2.
