iPod dock with amplified line out and charging? I have an Aux connector in my car that I'm plugging my iPod into via the headphone outputs. It's almost OK, but the sound quality isn't what it could be - the levels are too low, and cranking up the volume in the car exposes some low-level noise. There's also something not quite right about it that I can't put my finger on.

There are tons of adapters that plug into the docking port and expose a line out connection, which should be better than the headphone output. There are a couple of problems with these:


Most don't allow you to charge the iPod while the adapter is plugged in.
None have a built in line level amplifier. Some might have a headphone amp, but that just puts me back at square one. I'm not looking for more power, just a higher amplitude.


I have found a couple that allow charging such as the FiiO L11 and the PocketDock Line Out USB. Unfortunately they don't appear to have any amplification.

I hope there's something out there I've missed.
actually you do not need amplification. Simply use an adapter like the FiiO L11 (or another cheap 30-Pin > Line-Out + USB-Power-In) an you´ll be amazed: The sound will be way louder and way, way better than the one from the headphone-out. Trust me, I made an A/B-comparison with A=adapter and B=Headphone-Out, both connected to the Line-Ins of an DJ-Mixer and hardly could believe, how much better the sound was!
