MQA is fine as a niche thing if people want it. Had it become dominant it could have negatively affected the industry - end to end systems always have issues (HDCP!) - but so what if it exists at the fringes.
I think if there is going to be another streaming service it's going to need to be different. Having the same catalog alone doesn't make sense.
A streaming service that had the whole catalog and then exclusive content like white glove high quality remixes you cannot get elsewhere...that would be cool.
