Just got the hd 6xx headphones for $200. I am told an amp/dac will be needed for these headphones but it seems people recommend products that are $200+ personally I can not yet justify spending that much on an amp and dac. Someone recommend the JDS atom amp which seems like a good amp. Could I get buy with just that and no DAC? I have also just thought about buying the Fiio e10k or the q1 mark 2 even though it will be “underpowered” my thinking is that it will be better than just going directly into the PC.
