Thanks. A lag in the onset of sound could be many things. I'll take a stab at it by guessing it's your internet. By that I mean the connection between your Phantoms and your software player ( Apple Music ). Are you using a Mac computer to play music? It's not possible to use wifi ? The current software version of the Devialet app is designed to be used over wifi. I'll assume you have upgraded the app. I believe the current version is 1.16.1 although that's for my iPhone. You might try another software player. For example VLC. It's free and would help clarify that issue. Also, what is your internet speed? Keep us posted and hang in there annoying as that is.
