I used the ALO Rx MkII, RSA Tomahawk, and CMOY amp on my modded T-50RP, and I have to say the only one that really drives the cans well is the RX MKII. Tomahawk is more of an IEM amp, and CMOY struggles in the sense that it feeds too much extra noise to it.
I don't have a desktop amp, but I would love to see if anyone tried the Matrix M-stage on these babies. I always wanted to get the M-stage, and was wondering if they work with my cans.
BTW guys, if I am putting a direct cable, does the position of the drilled holes for the cables make a difference? Is there an ideal spot for the cables?
