The 550 watt system is probably the best stock audio I have heard in anything I have tested. I am somewhat of an audiophile. For me , this would be the only reason to step up to the touring trim. Sport and xle systems are ok but there is a difference.
If you test it, take your time to play with the audio settings to get it to your liking.
I listened to some Earth Wind and Fire while testing. Sounded excellent!
I also did not find it very difficult to learn the infotainment system.

I agree, also being somewhat of an audiophile a good sound system is important to me, and I don't want to go aftermarket to get one. The Passport Touring system sounds great. Plenty of bass with the subwoofer.
I also had a 2017 Ridgeline RTL-E and the Passport audio system is definitely better.
