I'm looking at the CDT Braxial Eurosport components, the CDT ES-630Z to be exact, with an upstage System 500 to put in the A-pillars. Do you have experience with this line and does it sound really good? Doe s the upstage system really lift the soundstage a lot? I've heard the CDT classics in a friends car and loved them, haven't heard the Eurosport Braxials and would like to know since there isn't a dealer I can hear them at anywhere close.
