Dunnersfella: The Pioneer is pushing an awful THD figure... 1%!
The Kenwood was 0.06% (lower is better).
At the time, that was Pioneer's very lowest receiver, and it won't have improved with age...
i cant find the spec on the web but this listing seems to have it at 0.7% at 100w
Stereo Mode Power: 110 Watt @ 8 ohm, 20 Hz - 20 kHz, THD: 0.7%
