Hi all! I really need your help guys! Does anyone have experience with this model? It's 13,3 inch, i5-3210m Macbook Pro (2nd generation, mid 2012). I need to know how loud this notebook can drive headphones through it's audio jack? I will be using quite demanding headphones and I like to listen to music loud, would it be suitable? Also, what is audio chip in this model? Cirrus 4206(something)? Thanks!
