Schiit Audio has replaced both their Magni 2 and Magni 2 Uber headphone amps with their new Magni 3 (a Magni 2 Uber on steroids) and as a result Amazon is blowing out the Magni 2 Uber for $79. Combine it with the $99 Modi 2 DAC and you have a Schiit Stack. The new Magni 3 is $99 direct from Schiit.
