No audio over HDMI on the 1609.
The 588 doesn't have HDMI at all.
They basically have the same power as the 1612 or 1613 so you might as well get one of them. Still dont think those entry level Denon's are good at 4 ohm loads.
i want hdmi i didnt notice... ugh... that denon is absolutely perfect aside from the hdmi!!! >_< why is this so hard?
Honestly, because you're being cheap.
