With either Apple Music or Amazon Music Unlimited I do not get perfect gapless playback. I say not perfect because there is not an actual gap instead there is something I would define as a “bump in the road”. Although this happens at every track change it is most apparent when the track change is during a loud passage.
Looks like I can’t attach a video to demonstrate the issue. So if someone with the system Arc-Sub-ERA 300s could try the above example and report back I would love to hear what you hear.
Try this link though.
