Really. With the Lyris I get the same lack of control in the bass, recessed and slightly smeared mid-range, and rolled off treble as I get with my PC's headphone out. Yes the lyris gets plenty loud, but I don't think any 9v battery powered amp will do much for the 580s because the 580s need more voltage to shine. The Lyris may provide some improvements in SQ but they are overshadowed by what the lyris can't do. I'm not saying it's a bad amp its just not designed to handle 300 ohm cans.
