The Porta-Corda drives the HD580/600 fine. The Corda HA-1 doesn't work on batteries but sounds quite a bit better than the Porta-Corda. The HD600 sounds a little better than the HD580, but the difference is quite small IMO. As far as the math goes, PC+600 < HA1+580. Unfortunately this goes for the price as well as the sound.
