I have an Asus Xonar Essence ST with Sennheiser IE80s plugged in, and being the audio newbie that I am, I have a couple of questions. :)
Firstly, should I be looking into getting an amp? The sound levels definitely don't need a boost, but I hear that amps are used to improve the quality of the signal? And if so, which ones should I be looking at to compliment my current setup?
And what about a DAC - I hear that some people use them with the Essence, sounds like overkill?
Secondly I have two small issues:
1. There is a slight hiss on the line. This doesn't increase if when I increase the volume. So far I have been using an old in line volume remote to lower the signal post audio card, which eliminates the hiss, but I am pretty sure (untrained ears) that it is colouring the sound.
2. The IE80 cable is too short. Currently using the same in line remote as an extension, but same issue with colouring. Do extensions usually colour the sound?
