So…. classically trained musician from a young age here, played at Carnegie Hall a few times, nowadays just have a crappy taste for pop / dance-pop / hip hop music in the car….. But I still serve on a few expert audio panels for user testing codecs and sound products, and have proven myself a few times in qualifying for these positions that I have an ear for discerning audio quality differences….
At any rate, I don't like waving credentials around, but I do agree that it's better, but not OMG THIS IS AMAZING better. I would expect most people to be able to notice a difference, and some people probably want to crank down the bass a bit compared to before, but it's not like a night and day difference like you put a soundbar on your flat-screen TV or replaced your stock iPhone earbuds with a $500 pair of studio monitors….
I'm pleased to see them making improvements though. As of 2.32.19, surround mode is still a little on the tinny side (A bit excessive treble to the point of being harsh), but it now has a noticeable and sometimes positive impact on stereo separation compared to before, when it just reduced fidelity.
