Hi everyone, I'm looking for some help choosing some new cans. I already have an HD580, SR125 and some decent amps (TTVJ portable, total bithead, cmoy). What I'd like is something with some bass slam that isn't as laid back as the senns and not as "unfinished" as the grados. I'm willing to spend...

I've been looking to get a portable dac/amp combo to power my HD580s. Has anyone tried them with the RSA Predator? Maybe another dac/amp? I've got a millett hybrid portable, but I need the dac for laptop listening, and I like how the RSA stuff looks.
