the Panasonic sa-xr70 has only one HDMI plug, you would have to use an HDMI splitter. But it's dirt cheap at $300 new so you could put the savings into speakers and sub.
you might want to look at the HK2005, not sure if it has HDMI or not but that's the only other all-digital I can think of.
Oh there are also some new JVC all-digitals that are coming out, I think the 402 and 702 are the higher end models, look them up on the jvc website for their spec/feature list.
