I recently got the ASG-1 headphones and completely fell in love with the warm bassy sound. However there is an imbalance (yes ive confirmed it, more bass on right side than left) and am going to send it back to Aurisonics. I'm considering having them upgrade it to the ASG-2 in the process. Is it worth it? Is it still pretty warm? With the bass port fully opened does it have more sub bass than the ASG-1?
