Thanks for referencing the AS review. I’ll check it out and have thought about giving Qobuz a try with their free trial as you stated to see if I can even notice the difference in SQ. Not sure if my ears are that refined.
With that said I have never really thought the quality on Amazon was lacking and have a number of times compared its sound to CD’s and LP’s. Also, when I have the time to sit down for a serious listening session I usually prefer to listen to LP’s that I do find to sound superior.
