hi guys, new to this and looking to upgrade my current setup of Sennheiser pc360, Logitech z506 and xonar dx to a reasonable setup.I have set myself a budget of around £1000 for headphones, speakers and any amp/dac required to power them - however im flexible if need beAfter some research I have been looking at the hifiman he-400 and the schiit M+M stack combo, my only issue is how i would add a set of speakers to this (2.0)Initially i was wanting to purchase a set of passive speakers such as the q acoustics 2020i for instance but then came across the audioengine a5+ which would remove the need for an amp to power them and i could also incorporate into the schiit asguard 2 as reccomended and use it as a preamp.The only thing that worries be about the self powered monitors route is no upgrade path.Could you please advise on passive speakers + amp vs the audioengines and also the best soloution for both passive and headphone on pc if that is the way to go.Thanks
