I'm wondering if someone who owns one of these and/or Paul can answer a question for me. I'm interested in the DX160 mainly for its sound quality and the 4.4mm balanced output. But I need to know if it is built rugged enough to actually withstand daily use as a portable unit while doing physical labor. I drive heavy machinery and run a sawmill. The DAP will be either in my shirt zippered pocket or a fanny pack. And I'm asking because I tried a DX50 and it's 3.5mm output was defective out of the box. Sounded pretty good if I held the jack in just perfectly and plays 24/192 but sadly is going back for refund. Too bad because it also has a hold/lockout switch that is an important feature for me. Sure looks like the output jacks on the DX50 are really low quality plastic and just can't withstand any stress at all. Has iBasso addressed this with the DX160? If not can you recommend any DAP's that are rugged, with a balanced headphone option, that can play at least 24/192? I don't need Bluetooth, wi-fi, or a fancy gui or os, just basic functionality and great sound (which seems to describe the DX160 more or less) Thanks!
