Sorry I know there are a lot of threads about amps suitable for the iPhone 4, but all the amps that have caught my eye have either been discontinued a long time ago or I can't find them regardless.
The only amp that seems to have stood the test of time seems to be the Fiio E11.
Everything about the Fiio E11 is fantastic, but I just cannot get over the fact that
the E11 is extremely finicky with charging, considering half the time I would like to use the amp for my laptop.
tldr; is there an amp like the Fiio E11 with similar low profile form factor and reputation that works great for iPhone 4 AND a computer that is also available right now?
