Where does ZK get power supply spec? Seems they're using the power consumption spec in the first mention of bigger power supply....then later on just uses same numbers for power consumption (and then for power supply spec just says 120V 60hz). Pretty good comparison chart otherwise....
@dmattern no the difference in power of 5 wpc is negligible (even a doubling of power only nets you 3dB spl and it wouldn't surprise me they basically share the same amp section from the specs). Biggest difference to me would be the Audyssey MultEQ vs XT, if that matters to you. Might check out connectivity, I see the 960 doesn't have zone 2 preouts if that matters, and neither unit has a full set of pre-outs (which is a nice thing to have, but you have to go up to the X3xxx and above series, but that would also get you Audyssey XT32).
ps Meant to add the Audioholics article on power consumption spec (not watt you think
)
