Seth is correct. There are some major differences in specs
between the 805 and the 7.7 that just can't be ignored.
The obvious.
7.7 is THX Select 2, vs THX Ultra 2 for the 805
HDMI 1.2 for the 7.7 vs HDMI 1.3 for the 805.
The not so obvious:
The 7.7 weighs in at about 30lbs.
The 805, if Onkyo's published specs are correct, comes
in at 50lbs !! I would assume that most of the extra weight
went into SERIOUSLY beefing up the power supply to attain
an Ultra 2 power rating.
7.5A draw for the 7.7 and 9.5A for the 805.
I'm sure Integra will be updating their line very soon, but as
it stands now, the 805, at lease power wise, will probably smoke
the 7.7.
