I am certainly not the expert in closed cans, but a couple questions that may help get you closer... 1) Are they primarily for home or portable use? 2) Are you planning on using an amp? If so, which one? 3) Have you considered Beats By Dre Studios? JK on question 3
I don't think your question ever got answered, but if I missed it, my bad! Yes you can run 3 amps simultaniously off the Gungir ( XLR, 2 RCA). I have mine hoked up to Mujlnir, and i2 other amps. I run multiple at the same time quite often.
Here is the current work station:
Aune T1 w/ amperex 7308 gold pin
Beyer Dt-250 250 ohm
Loving this combo and a bit surprised the DT 250 gets so little love. I've only had it for 2 days but I am finding it detailed and balanced. It isolates well and there is NO bleed. A great work solution!
Here they are out in the wild:
I agree with the general consensus on this thread... they are an unappreciated headphone. I can't believe they fly so far under the radar. I don't think I have ever seen them recommended in the under $200 price class, but I think they punch way above that level. Great isolation and almost no bleed makes them the perfect work solution!
