I'm thinking of ditching my Windows laptop and going for a MBP 15. I'm happy with everything I've found out about the Mac and am almost throwing my money down, but I can't find any information on the Audio within the MBPs. My Windows laptop (HP Envy) has a Beats whatever system in it and the sound is quite good. I've been using a MBP 13 for a few weeks to get used to it and the sound out of it is quite tinny, there's no bottom end. So I'm wondering if anyone here can tell me what the sound is like on the MBP 15s???? I'm in Australia and I'll be buying new if that makes any difference to anything. Thanks for any help.
