Yeah I take it pretty seriously. I actually have a Butler Audio 475 Tube Driver amp that has a couple of 6SL7GT tubes in it. Some high end focal speakers, and an additional sub and amp. Lots of dynamat for vibration control and damping. And of course a good head unit with Bluetooth. CDs still sound the best. A skilled and patient installer is a must. Sounds pretty darn good! Problem is my wife drives the car except when we go on road trips!
