I have the loxjie D40 but I still used it very little, but I also have the Loxjie D30 which has a similar system and which I have been using from the wheel for all functions for over a year and has not the slightest sign of failureYes it's pressed on, not screwed (plastic on plastic) and even that it looks like there could be solutions to it its rather frustrating to pay 500 for a dac and not have an adequate building quality...for gentle use.
