If you guys have some free time go over to the Lexus dealership and listen to the Mark Levinson Sound System in the GS430... FANTASTIC!!!! Use the settings Trebble 5 Bass 5 and Mid 0 ..... That seems to sound the best... There seems to be less trebble and bass than the Nakamichi sound system so it sounds perfect while turned to Max levels on the Mark Levinson. As I said in an earlier post, the Mark Levinson system alone is enough to sell the car... Has anyone else listened to it?
