I have my isp line on custom shielded Dc cables all LPS and respectable after market power cords as well as fiber optic after the router to further isolate noise from Sonore Deluxe Ethernet to optical and yes a minimum of16 megs of ram and a intel 7-9 processor ,and 1 T of SS drive dedicated just for the DSP for HQ player is necessary to have Optimum performance and several weeks to truly learn
allHQ players abilities with Roon , I am just starting to dedicate any quality time
I have seen m6 brothers results and it is fantastic and sounds great ,Thst being said it will expose any weak link in the chain I estimate at least $10-$15 k for a quality digital setup from start to finish ,which then it’s truly digital at its best
the latest T&A 200 dac ,is excellent and has HQ player with a bunch of filters and dither built into the dac , preamp and very nice looking as well as superb digital playback , at around $7k I feel a bargain and will meet or compete anything up to 2x its cost , depending on your taste but it has many filters and a dedicated 1bit DSD section.
