Hey everyone, I am a little confused about some ratings on my audio equipment I was hoping you all could help me out. I have the following:
HK citation 19 2ch amp- weighs about 45lbs
100wpc manufacturer rating with a 660w power supply (330wpc rating)
Marantz mm500 4ch amp -weighs about 25lbs
80wpc manufacturer rating with a 210w power supply (52wpc rating)
Integra DTR 40.1 11ch receiver -weighs about 30lbs
100wpc manufacturer rating with a 744 power supply (67wpc rating)
Now, I understand that there is nowhere near a 100% efficiency rating for these power supplies. And all of these items are what I would consider upper mid grade quality. (Maybe the HK was top notch in the 80's) but even at 100% efficiency, these guys, save the HK, are not even approaching their started power rating.
Is the HK under rated? Are newer power supplies significantly more efficient, or are integra and marantz full of crap(rated at 1ch only for a fraction of a second)?
