Ashman,
What kind of high end amplifiers are you thinking about when you talk about lots of clean power? I recently called Harman International about the supposedly High-end system they put in those Lexi and couldn't get much information. I don't really want the car audio to sound like my audio at home, but there are certainly some characteristics that I like, specifically tube power and ribbon tweeters!
Perhaps this should be a different thread!
