@iFi audio , If not using any mqa Is there an advantage to the older firmware for dsd when only playing dsd64 and 128? Is the older firmware better in responsiveness with those files or does it sound better since I don't intend to use mqa or dsd above 128 for that matter? Heck, does the latest firmware also affect pcm? EDIT: I also noticed that the manual for firmware 5.20 talks about 5.2A and 5.2B but the actual files in the archive are 5.20 and 5.2A. Is 5.20 version B? and for use with an ipad 2018, would I use that over 5.2A? EDIT again: I tested 5.2A and so far as the behavior is concerned, I did notice that it sleeps. Is that for safety of the LiPo batt? Other than that, I do like it on all the time and wished it had a mode where it didn't charge when I don't want it to so that it won't be trickle charging all the time without having to go to battery power mode where it also makes it discharge and need more charging ending up in battery wear and tear.
