Mark Levinson 21-speaker audio sounds terrible on the GX 550 Luxury +

Hi, would you message me and let me know the problems you have with your ML system? I use the same dealer and would be helpful to know how to relate these issues to them for the parts replacement. Thanks!

The sound is not great compared to our LX and earlier model GX with the ML systems we have. The GX550's version is far below the quality sound. but the main issue is anytime volume went north of 30 the bass cuts out and sound gets distorted. Almost as if the amp shuts down completely. I can open the hatchback and listen to the sub for a few minutes and then it cuts out completely as if it doesn't exist.

I noticed the ML in my GX550 is tame compared to the previous GX460. The ML in the wife’s RX500h sounds really good - no real distortion at high volumes and gets really loud. The ML in my previous GSF wasn’t bad either. Do you think the amp is bad on all the new GX or only selective ones? Changing out the head unit sounds like a big task. Not sure I want them tearing apart a new vehicle. Thanks for your reply.
