I have the standard HK. It is basically the same I have had in my previous vehicles (logic 7) and love it. I am somewhat of an audiophile so know the difference. $3500 is not worth it IMHO even with the lights and pop up. More to break. Besides the way I drive it, I am not critically listening to Mozart on it. Maybe Rachmaninoff. Most often AC/DC. I would not make it a deal breaker.
