As the current owner of a Lexus LS sedan with a Mark Levinson radio and a Volt Premier with a Bose radio, I can say the Lexus system is the without any doubt the clear winner. The Levinson makes the Bose sound like mud. The clarity is instantly recognizable. It's almost like putting on headphones versus listening to speakers... you hear things you didn't know were in the song. It would be hard to find a better sounding radio in a car than an LS with a Levinson. It takes more than volume and base in my world. I love driving my Volt, but lust for a much better sound system, especially since the car was born quiet. I'd put quieter tires on it if it had an outstanding radio. The two cars I'm comparing here are apples and oranges price wise so this should not be shocking to anyone. The Lexus doesn't have Apple Car Play... shame on them.
