I do currently own Sennheiser HD558, ATH M50, Grado SR80i and out of them, i can say i do enjoy the sound of M50 relatively more. I run them off my iPhone 4 + Fiio E6 and they sound fine.
As an upgrade, i ordered Schiit Magni and Modi DAC+Amp combo(for desk use only of course) and they should soon arrive. I also wanted to get a pair of DT770 250 ohm.
1) While DT770 250 ohm sound good with Schiit stack? or should i go with 80 ohm model? Plz consider that i currently like sound sig of ATH M50.
2) Any alternates to DT770 that make the upgrade to Schiit stack worth?
Budget is around 200 $. But i am willing to stretch a bit if necessary
