So you're using different hardware (some of which is an Echo/Alexa device and the other the Wiim?) For playing the two streams? What is the exact setup?I’m aware about that in fact I even turn the volume on amazon. It made it louder but not sound better. There were some textures on music that quoboz has that amazon was missing these were repeated played many times over. Could it be on the mastering or the software within Alexa that impacted the sound? Ifi stream on exclusive mode meaning turning off unnecessary services on that you don’t use made difference on their device like all in one vs tidal connect only. Bottom line, I’m not the only one who claim this so does reviewers from internet like what hifi? and other forum all over internet.
