On The Bench (AV8003 Only)
At 1 kHz and 0.5 volts output, THD+N was less than 0.003.
Using a combination of 19 kHz and 20 kHz sine waves, the B-A distortion product at 1 kHz was 92 dB below the fundamemtals.
IMD, using 60 Hz and 7 kHz sine waves was a low 0.0015%. This is exemplified by the lack of peaks surrounding the 7 kHz fundamental peak.
The frequency response was flat to 20 kHz, where there was a steep rolloff. The test signal passed through the Marantz' DSP circuitry, rather than "Direct", and an induced rolloff above the audible band in receivers these days is very common.
