Hi @maxmp - thanks for all your efforts on this. Seems like there are multiple requests from FiiO M11/X5iii owners. The M11 is soon (likely next week) to be released in the US and Europe, which is going to lead to high demand for hi-res music software. I’m going to be writing a full review on the M11 and using Poweramp as an example, and I’ve already heard from numerous users waiting to buy Poweramp as soon as it supports hi-res headphone output on the device. I imagine adding support for the M11 and X5iii should be very similar so hopefully not too much extra work for you! Thanks again in advance and look forward to the revised build.
