Hello, I recently ordered the Sennheiser HD600 headphones for casual music listening. I was just wondering if my 2015 Macbook Pro would be powerful enough to push these headphones for the time being while I wait to order a Schiit Audio Fulla 2 AMP/DAC? I did previously have a pair of Sennheiser HD8 DJs but there was a fault with them so I exchanged them for the HD600s. The HD8 DJs would get super loud (at half way) on my Macbook from the motherboard audio. So I was just wondering if I would be okay with the HD600s on my Macbook until I order an AMP?
