So I recently ordered an HD 800S which I'm still waiting in mail. So I decided to look around for the best AMP/DAC combo around Head-Fi but I still couldn't find the right one for specific "Sennheiser HD 800S" under $1000 USD. I can go over a little bit up to $1,200 but nothing more. I heard good things about Schiit Jotunheim however, I've heard that it's a bit too bright for HD800S Currently I have SMSL M6 and a Sennheiser HD598 but I don't think SMSL M6 Is powerful enough for it.. I'm thinking of Gustard A20H and I've heard good things about it, any recommendations that would help me choose an AMP/DAC for HD800 S? I would prefer to have complete solid state because I don't really want a maintenance. Thanks!
