We're not impressed at all. Our 2007 Edge SEL with the audiophile 9 speaker system sounded great, but this 12 speaker Sony system just doesn't cut it.I think I'm going to go to the dealer and compare it to other 2015 Edges with the Sony stereo. Currently I have the treble gain all the way up and the mid and bass adjusted all the way down. Will play with it some more we've only had it for a couple of days. It has a very monotone sound.
