I currently own the HD-A1 player and have it hooked up to my Harman Kardon receiver through the Digital Coax output. Video goes straight to the projector through HDMI and it works great. Now with the lack of the digital coax output on the HD-A2, what's the best way to hook up the audio? I guess my only choice is optical since my receiver has no HDMI inputs?? The new Harman Kardon receivers have HDMI inputs but the manual suggests that a separate digital coax connection is still required for audio. Why did Toshiba get rid of the digital coax outputs??
