Maybe top tier for your average consumer-grade stereo equipment, but there are many brands beyond what is listed here.

Most expensive I’ve heard was Focal Sopra 2’s, Naim Solstice turntable, and a stack of Naim pre and power amps.

I had a 2016 Audi Q3 with a Bose system that I was actually somewhat impressed by considering Bose’s typical sound.

After that I had Fender in my 2019 Golf R and found it to be bright and a bit harsh. Always had the treble and mids EQ’d down.

Now I have Harmon Kardon in a 2023 Kia Sportage and it’s adequate. It doesn’t blow my mind, but I also never notice it sounding bad.
