Got some new HD 600s and, when connected to the HM 801, they could use some help. The HM really does not seem up to the task of powering the Senns. So, I've been considering the purchase of a headphone amp but, I'm also tempted to buy a small inegrated amp from NAD C 316BEE instead. It seems like the NAD would be a more versatile solution.
Am I missing anything?
