Does anybody have experience with this product?: http://www.sendstation.com/us/products/pocketdock/lineout-miniusb.html if so does it noticeably improve the sound quality of your iPod/headphones? I know it would be better to get an amp for an iPod but this is temporary until I figure out which headphone amp I want.
Depends. If you use a noticeably better DAC than what is in your ipod, then yes. It really depends on your setup and how much money you are willing to spend on a new DAC. I have never heard the actual product, just generalizing.
