I may be an outlier, but I don't think the system, after 32.5 anyway, is bad. I think it sounds pretty good in fact. I'm a fairly discerning listener with a system at home that is very good. I'm on the older side, though, so perhaps my hearing isn't up to par. However, the comments on the system not being any good don't appear to be limited to just 'can't hear higher frequencies', which I may be missing even at home.Weird. Did you wait for the 2021.32.5 audio system update before doing this?
I'd try it out with your favorite music on a 44/16 FLAC file on a USB before deciding on changing it out with an aftermarket system.
