I've had my 2021 M550 for a little over a month, which replaced a 2018 540. Both with the Harmon Kardon stereo.

Something about the sound in the 2021 seems a little off, and I have observed that sometimes the bass/low end will just drop out for a second.

I seem to recall a post where someone else reported the same, but for the life of me can't find it.

Anyone else observing this? I'm wondering if something is loose or if there is an issue with the amp.

Looks like I'll be bringing it in to be checked, but just curious whether others have had any similar experience.

Thanks.
