Fraza44 - thanks for the info
I just received the Onkyo HA300 - impressed by first few listens, and love how the volume can get a further boost by gain. But compared to the Pioneer I'm not sure if the Onkyo is worth keeping. The sound is good on both, but the Pioneer has longer battery life, room for 2 memory cards, and can play ALAC when used as a DAP.
