First, I've had the car only for a month. And, I'm in that small minority that listens mostly to classical music or Coltrane era jazz and pre-80s jazz singers. But, also love a variety of music from Bluegrass to Soul music. I have learned that the quality of sound I get out of the system depends on the quality of the recording being played. The Levinson system does do a good job of resampling and improves the quality of everything. But with a quality hi-fidelity recording it sounds like I'm in the best seats of a concert hall. I have seen the difference even in different songs coming through Google Music or the radio. Some recordings are more equal than others. And garbage in, garbage out.
