Thanks, I will definitely check the ARC Mk2 out.
So just to clarify, are you saying that:
1. regardless of whether it is a built-in motherboard DAC or extenal DAC, there won't be any noticeable difference in case of my AV40 monitors? In this case is there anyway to improve their current audio performance (clarity / sound qualify) by any other means other than DAC?
2. You would only recommend a set of DAC + AMP in case of using decent headphones? In this case 2 follow up questions, would you be able to recommend a decent set of headphones to utilise the maximum potential of the Amp/DAC you have suggested and secondly if I do end up plugging my AV40s into the suggested AMP/DAC combo, could there be any issues with there being and internal and external amp's used at once or would they supplement one another?
Cheers
