The Pioneer SX-1980 was rated at 270 wpc...however, in the September 1978 issue of Audio Magazine, Leonard Feldman did a spec test on the SX-1980 and concluded that the rating of 270 watts per channel was too conservative. He 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 460 watts per channel (2.3 dB dynamic headroom) into 8 ohm loads with THD 0.03%...even beating the Technics SA-1000... doesn't this technically makes the Pioneer SX-1980 the most powerful receiver ever manufactured? What do you guys think?
