Looking for a DAC/AMP combo to BD DT 990 Pro cans (250 ohm version) and condenser mic for my son. Needs are 1) Phantom Power (for mic) and amp with enough power to properly run the DT 990 Pro's at 250 ohm's. Now I was going to order a Schiit Fulla 3 or Hel but realized they don't support phantom power. I was looking also at the Focusrite Scarlet Solo and 2i2 (great mic pre with phantom power) but I can't find any information about its headphone amp quality, if it can adequately power the DT 990's. I few stated that the headphone amp might not be up to par. Any other suggestions out there please?
