#teraHD , Incase you are looking for an amplifier to use with an iPod you are better off with a Fiio E6 or Fiio E7 depending on the budget .
If you are looking for a sound card (DAC) for the PC + portable amplifier , get the Fiio E7. You will get superior sound when using it with PC( usb) and also a better output when used as amplifier with iPod.
