I love my new iPad mini and don't consider last year's A5 chip or lack of retina to be a deal-breaker for me. However, the sound quality from the headphone out is thinner and not as rich as its full-size brethren (I have the iPad 3). I'm a real audiophile nut and use really good headphones (Ultrasone Edition 8) so this matters to me. I'm not saying the sound quality from the headphone out is not good on the mini, it's just not as great as it is on the iPad 3. My conclusion as to the cause is that the much smaller battery (15w as opposed to 45w in the iPad 3) is not pushing as much power through the amp/dac system, causing the thinner sound. I'm sharing this to see if there are others out there who have also noticed this? I'm disappointed because I really love the mini in every other way but may return it and keep my iPad 3, just for this reason.
