Here's what the manual says:
Rated Output Power
All channels: (North American)
135 watts minimum continuous power
per channel, 8 ohm loads, 2 channels
driven from 20 Hz to 20 kHz, with a
maximum total harmonic distortion of
0.08% (FTC)
160 watts minimum continuous power
per channel, 6 ohm loads, 2 channels
driven at 1 kHz, with a maximum total
harmonic distortion of 0.1% (FTC)
145 watts minimum continuous power
per channel, 8 ohm loads, 2 channels
driven at 1 kHz, with a maximum total
harmonic distortion of 0.7% (FTC)
(Others)
7 ch × 180 W at 6 ohms, 1 kHz, 1 ch driven
of 1 % (IEC)
Maximum Effective Output Power
(Asian)
7 ch × 230 W at 6 ohms, 1 kHz, 1 ch driven
(JEITA)
Dynamic Power*
* IEC60268-Short-term maximum output power
300 W (3 Ω, Front)
250 W (4 Ω, Front)
150 W (8 Ω, Front)
THD+N (Total Harmonic Distortion+Noise)
0.08% (20 Hz - 20 kHz, half power)
Damping Factor 60 (Front, 1 kHz, 8 Ω)
Input Sensitivity and Impedance (Unbalance)
200 mV/47 kΩ (LINE)
2.5 mV/47 kΩ (PHONO MM)
Rated RCA Output Level and Impedance
200 mV/470 Ω (PRE OUT)
Maximum RCA Output Level and Impedance
4.6 V/470 Ω (PRE OUT)
Phono Overload 70 mV (MM 1 kHz 0.5%)
Frequency Response 5 Hz - 100 kHz/+1 dB, -3 dB (Direct mode)
Tone Control Characteristics
±10 dB, 50 Hz (BASS)
±10 dB, 20 kHz (TREBLE)
Signal to Noise Ratio 110 dB (LINE, IHF-A)
80 dB (PHONO MM, IHF-A)
Speaker Impedance 4 or 6 Ω - 16 Ω
As a 2 channel amp on a test bench pumping sine waves into an 8 ohm resistive load, calling it a 135 wpc amp would appear to be both legal and technically sound.
If you called it "Yet another 100 wpc AVR" you'd be good.
The extra 35 watts and $2 will get you a cup of coffee in most US Starbucks. They mean that the AVR can play about 2 dB louder than an actual 100 wpc AVR, which is a discernible but not all that noticeable amount of additional loudness.
I'm more interested in this: "Audyssey MultEQ® XT* "
