if it's for pure stereo, with no virtual surround then the Schiit Modi 2 and Schiit Magni 3 duo sound very good.
if virtual surround is needed then the Asus STX and STX II are able to drive the HD650s with ease.
My understanding was that you could use optical from sound card to the Modi and keep the surround?
So would my SoundBlaster SBX suffice as that has the Outputs,
So it will be a red/white cable from this to the inputs of the Magni 3?
Does that make sense? I suspect maybe I need a better DAC.
I thought that but the Modi Multibit changed my mind, there are no "night and day" differences in the world of DACs but with well recorded music it just sounds better than my Modi 2 - better separation and imaging, more realistic bass, subtle changes but there nonetheless.
I've just received my Magni 3, I must be stupid but there's no USB in so how do I connect it to my pc?
The Modi 2 is a very good DAC and is as good as most people need
I disagree. I find it rather shrill and clinical sounding. Not a very impressive DAC. I had the Modi 2 Uber, hated it, and ended up selling it recently. Arcam's cheaper DACs such as the rPAC are slightly costlier but sound more natural IMO. The cheapest Schiit DAC that's worth the money is the Modi Multibit IMO.
