I was so glad to see all of these comments regarding the radio. I have spent most of the day today trying to find a replacement for the standard "Premium Sound System" in my new GS300. For the past 14 years I have driven BMWs and this was my first Lexus. I didn't even think to try a CD in the radio before I bought it. I just assumed that the stereo system would be as good as the car. My last BMW, a 1998 528i, had the most incredible audio system, so I was spoiled. I agree with Torrent that no amount of tinkering will make the sound decent. I also agree with his later comment about how "it really lets down an otherwise damn near perfect car." I think the car is perfect, except for the audio system. I am going to try replacing the front door speakers and tweeters. Let me know is anyone else has tried Stevie's idea. Thanks for the comments.
