Up to 24/48
I hope they don't charge more for albums that are already "Mastered for iTunes," in which Apple already has the high-resolution files in their database.

btw, i have a O2 that I may use as the the Amp but would love a very portable amp-dac solution.
It really depends on how the DAC chip is implemented, just like op-amps. You can have the best DAC out there, but if it's poorly implemented, that "best" DAC is pretty limited.

As a general rule for bass control:
Headphone Impedance / Output Impedance >= 8
With a 5 Ω output impedance, that typically works well with headphones of 40 Ω or more. Anything less and the bass response will probably affected in a negative way (looser, woolier, etc.) and is especially bad with multi-driver earphones, where the phase linearity and output impedance values can change a lot based on the frequency.
