I find that by using a USB to Audio interface not only is the sound better (more bandwidth - lower lows and higher highs) but the reliability is better than by using the headphone or speaker jack.

If both are set for 16/44.1 and the source mp3 file is also going to be that, there is no wider bandwidth available, regardless of the soundcard's capability.

Most modern laptops are fine for playing mp3/wav files.



This is correct.

Just be sure to turn the software playback faders ALL THE WAY UP when driving a Line, inclusive of any Master Fader that may be there. Adjust Volume using the physical controls on the amplification system and not the software volumes.
