I was looking through the manual for my Panasonic SA-HE200 today and I noticed something odd. In the specifications section, under the power heading, it said power consumption: 350 watts. Whah!? This receiver rates itself as 130W x 6 (Granted this is at 6ohms, but still). What exactly is the 350 measuring? I had my friend look up the same number on his Sony STR-DA3ES and it only had 420 Watts. What is going on here?
