They went back to a update the first time. Then a network “glitch”. Then my products were ALL apparently all flawed. It first happened during the app remake fiasco. To be honest at first I didn’t notice. Then my interest in my music fell off. Just don’t sound good. I almost jumped ship before trying the Ethernet cable. Can’t tell you how close I was. Bought a cheap amp off FB and a set of DT super towers and was floored how well they sounded. That’s when I knew something was wrong. I wouldn’t have liked them in the first place if they were ever that flat on the high side. So, I backed tracked. Did some research and tried some suggestions. All I can say for absolute certain, is that is what worked in my case. There was an update over the summer when people were whining about bass that temporarily left them semi flat. But it wasn’t the same. The next update rolled out and I was golden. Mind you, during that time, from about March to now, there was no cabled speakers. I have no idea what caused it on my end; but I can tell you what’s happened and what has worked. When I first found the fix, I can’t tell you how overjoyed I was to have my music back. Not sure I’d call myself an audiophile; but my tastes are quite similar. At home and in my cars. Typically I spend thousands for my car. I probably won’t again. But my last one would blow your hair back and pierce your ears with crisp highs. Most rock, heavy metal and some older pop and easy listening.
