On test, with both channels driven into 8-ohm, non-inductive test loads, Newport Test Labs measured the power output of the Roksan Attessa as being 82 watts (19.1dBWw) per channel at 20Hz, 86 watts (19.3dBW) per channel at 1kHz, and 80 watts (19.0dBW) per channel at 20kHz, so it exceeded Roksan’s specification at the two lower test frequencies, and was spot-on spec at the highest. Tested with just a single channel driven, the Attessa’s output was measured at 97 watts (19.7dBW) right across the audio spectrum.
When both channels were driven into four-ohm, non-inductive test loads, Newport Test Labs measured the power output of the Roksan Attessa as being 130 watts (21.1dBWw) per channel at 20Hz, 132 watts (21.2dBW) per channel at 1kHz and 130 watts (21.1dBW) per channel at 20kHz, so into this lower resistance the Attessa exceeded Roksan’s specification only at 1kHz, while matching it exactly at both 20Hz and 20kHz.
