Your experience with DACs is similar to mine. I originally purchased a Cambridge Audio DAC Magic and then upgraded to the Auralic Vega. HUGE improvement in sound quality! I then started reading about the Chord DACs and was able to demo a Chord Hugo TT2. WOW!!! The difference in sound quality to me was STUNNING! I would recommend you demo a Chord Hugo TT2 and skip the Chord 2QUTE. It may cost a little more, but the difference is amazing!
I use an AudioQuest Carbon USB cable between my PC and DAC and the sound is incredible!
