The Pioneer SX-1980[1][2][3] is an AM/FM radio receiver that Pioneer Corporation introduced in 1978, to be matched with the HPM series of speakers. It was rated at 270 watts RMS per channel into 8 ohms, both channels driven. However, in the September 1978 issue of the magazine Audio,[4] Leonard Feldman performed a specification test on the SX-1980 and stated in his report:

Though the new [IHF mandated] "Dynamic Headroom" measurement is specified in dB, it should be mentioned that based upon the short-term signal used to measure the 2.3 dB headroom of this amplifier, it was producing nearly 460 watts of short-term power under these test conditions!
At an official rating of 270 watts RMS per channel into 8 ohms[1] with a measured 2.3 dB dynamic headroom,[4] this makes the SX-1980 Pioneer's most powerful receiver, as well as being one of the most powerful receivers ever manufactured in the world, to date. It was also tested in the December 1978 issue of Stereo Review.[

All i want to know is why would they make such a powerful amplifier back in those days when they almost didnt have speakers to handle that sort of power? Good on them to create such a fine machine!
