Just got this in the mail today from last month's MassDrop and finally got to hook it up. I've been waiting for this unit for quite some time. I have a pair of AKG Q701, K271MKII, K44, Beyerdynamic DT770 pro and Harman HARKAR-BT.
I've been wanting to get the most of the 271MKII...so I'm firing up my Thriller flac files right now......... so far on the Q701's they're able to amplify them to deafening levels and I'm hearing things I've never ever heard in the 30 years of "Thriller".
