Though what I'm searching for is hard to find (ask for one, get less of the other, etc.), I don't feel that it is too contradictory of a request.
Though the majority of DAPs that fall in one category (eg. SQ) lack in the other (eg. battery life), there are some out there that fall in the respectable middle ground, of having above average SQ (though probably not the best, but at least better than Apple products), and decent battery life (around 50+ hours).
Some Cowon products fall near this category (of course, SQ is a personal opinion), but I'd still like to rake in other peoples opinions on DAPs they have used that they believe sound good to them, and have a decent battery life that fits their lifestyle.
* Just want to add that though I would be using over-ear headphones (MHP-839), a tablet of such size is not what I am looking for, and even if it fit both SQ and battery life requirements, the size factor would be the reason I would pass by it.
