This graph shows that the TX-RZ1100’s left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1% distortion at 124.8 watts and 1% distortion at 184.2 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 133.5 watts and 1% distortion at 255.6 watts.

There was no multichannel input to measure. THD+N from the CD input to the speaker output was less than 0.006% at 1 kHz when driving 2.83 volts into an 8-ohm load. Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –88.15 dB left to right and –85.33 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –104.77 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures –0.01 dB at 20 Hz and +0.76 dB at 20 kHz. The center channel measures –0.01 dB at 20 Hz and +0.89 dB at 20 kHz, and the left surround channel measures –0.01 dB at 20 Hz and +0.87 dB at 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is –0.00 dB at 20 Hz when referenced to the level at 40 Hz and reaches the upper 3-dB down point at 110 Hz and the upper 6-dB down point at 118 Hz.—MJP

at over 43 lbs this supposed 140wattx2 (125watts in reality ) weighs 10 lbs heavier then an sc95 and puts out less power is there a brick hidden inside and you'ld think if they were going to use the d3 amps maybe they should have used the EQ as well it would have made more sense then developing something that took everybody else years to do before they got it right

Good review. I recently got the TX RZ810 and whole heartedly agree with your review. The sonic signature you describe is exactly what I hear with the 810. I've had a whole slew of amps and receivers and this one is unique. Detailed, powerful, and clear. Yes clear. For some reason this amp just sounds clear. The measurements for the 1100 show a 1 db high frequency boost which I seem to hear in the 810 as well I wouldn't describe this amp as bright, but it does lean to that side ever so slightly. Great amp the 810 and probably gonna buy the 1100 for my other place. Sounds awesome. Running the 810 on Klipsch RP 260, RP 250 and RP 440C btw. Good movie set up and reasonably priced.

Sadly the A/V receiver will soon become a specialty niche product, just as separate components are now (pre-amp/processor and Amplifiers).
That is to say only dedicated videophiles will be on the market for them.
A decent desktop in the near future will be able to do all the processing that a good A/V does now. It is the Amplifier that will continue to live in some new iteration as part of any A/V system.
A/V receivers are simply highly over priced considering that good speakers and source players are affordable in comparison.

I recently purchased the Integra DRC-R1 Pre/Pro which is also an Onkyo product.
Am very happy with the sound but It has the same very poor online manual. I have contacted Integra to find out if there is a more complete manual available. They say that there isn't one.
The remote is also very basic for this level of product and is not backlit.
Very frustrating!

This review belongs in the "Electronics/AV Receivers" section, not in the "Displays/4K Ultra HD TV" section of the reviews. I actually had to find this review on Google because it isn't listed in the proper section.
