Ultimately on a truly portable dack+amp or dongle I'm not going to slag them over lack of balanced.
Is balanced better? Yeah sure, in theory, in practice this is conflicted. With IEMs or basic ear buds single ended is fine almost all the time. (I'm avoiding 18 drivers per IEM type monsters on here, which at that point just get a fucking DAP). What really wants balanced is large over ear sets. Single ended is good enough for non demanding things over short cable runs. Balanced also guzzles power like an alcoholic in a brewery.
I get that it's a selling point, and that's all fine and good. But this sort of "it can run my open backed planar magnetic cans just fine and it's the size of a AA battery, but cuts my battery life in half is sort of silly. As is slapping an upgrade cable that's 50-150 bucks that has balanced onto a 50-200 buck DAC/AMP dongle and then routing it to a 150 buck set of IEMs.
It's fine and nice and all to have but it's not a deal breaker or even needed for most people. It's not idiotic like BT or MQA.
