Thanks. A fun read.

I can't comment on any of the others, but we've had two cars with Bose audio systems, and your comment about "Want to reduce volume . . ." really comes home.

Both systems are grating at mid-volumes. I'm always finding myself toggling between loud enough to hear what's going on, and quiet enough to not hurt.

Both have super harsh mid-ranges, and worse trebles.

It strikes me that the factory stereo in my cheap Toyota pickup is easier to listen to than the Bose systems in our Acura and Porsche. There's something screwy with that.
