As far as the performance of the Mark Levinson in my 2023 ES300H, I find that the tone has been improved. In past ESs I have had to make large adjustments to the treble, mid, and bass adjustments to get satisfactory sound. Very odd to me that when set to flat, the tone was terrible with WAY TOO MUCH TREBLE.
Also, using a flash drive plugged into the USB in older ESs, the volume had to be set very high (sometimes at the max of 60). I thought it might be because it was recorded too low, but the same flash drive had no such problem when played on other devices. The my new Lexus no longer has this problem.
For the first time, I am totally satisfied with the sound of the Mark Levinson.
