I have a few questions on the Apple Universal Dock. Right now I have my Touch connected to my stereo via a 3.5mm to RCA cable plugged into the headphone jack, and the AUX jacks on the receiver. 1) Does the line out on the dock sound appreciably better than using the headphone jack? 2) Is the volume on the line out 'louder' than the headphone jack? I have to turn the volume on the Touch to near max to get usable signal to the receiver. (Kind of a pain, sometimes literally, to remember to adjust the volume down before deafening myself with headphones.) 3) Does the volume on the line out vary with the volume control on the Touch? Or is it a true, fixed volume, line out? (I'm guessing since the remote has a volume control, not.) 4) Is there another dock out there besides the Apple dock? $50 seems pricey, especially since you still have to add a power block and cable to it if you want to charge. I don't need the remote either. Mainly, I'm wondering if there are better alternatives to getting quality sound into my stereo. Thanks.
