@tdockweiler -- Thanks for your impressions. I look forward to an update after you've had a chance to listen for a few weeks.
My secret hope had been to find that the Magni and Modi performed so closely to the Mjolnir and Gungnir, that I could sell off the more expensive equipment, and reclaim some real estate on my desk. Unfortunately, that wasn't the case. My own experience is that amps and DACs can have a very strong effect on how headphones sound. The differences go way beyond a simple change in the EQ profile, but certainly include that too.
Well, aside from how expensive they are, Mjolnir and Gungnir are probably the best looking DAC/Amp combo being made right now.
