@Evshrug. Thank you for your response. So in your opinion it's not worth adding an amp because the audio quality increase is just a fraction better? I was already checking into op-amps & that sounds like a good possibility. Would the power adapter upgrade be worthwhile?

Been using this guide since 2013 & recently joined because I need expert advice as I have a lack of knowledge when it applies to audio.. I used to have the mixamp pro with a schiit amp connected to my PS4. I have gotten rid of both because I had quit gaming for some time due to circumstances...
