Hi,
I am also finding the Mark Levinson sound system dissapointing in regards to the Bass Output, and volume levels, sounds rather "Tinny", even after setting Bass, Mid and Treble set to maximum, the standard sound system in my RX350 (2006) had a fuller sound.
Am also finding that the quality of sound from the DAB compared to AM for the same radio station eg. Magic 1278, is much "thinner" and not as loud for the same volume settings.
Another gripe is that the order of songs being played from a USB, doesn't follow the order in the directory folders, checked the options for random and shuffled play but havn't got it worked out yet, will have to go back to the dealer to query this.
