both the SA-9500 and SA-9500II manuals quote 4 ohm specs

SA-9500: 80 wpc into 8 ohms @ 0.1% THD; 100 wpc into 4 ohms @ 0.1% THD
SA-9500II: 80 wpc into 8 ohms @ 0.05% THD; 100 wpc into 4 ohms @ 0.1% THD

The relatively small output increase into half the impedance (and the better HD 'spec' for the "II" into 8 ohm relative to 4) suggests that - by modern standards, at least - these aren't really "high current" amplifiers... but I wouldn't necessarily hold that against either version! ;-)

all the best,

Not a huge Pioneer fan m'self, but the SA-9500 is a NICE amplifier - mhardy6647 14:20:40 02/25/14 (3)
