This graph shows that the AVR-X3400H’s left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1% distortion at 123.0 watts and 1% distortion at 147.6 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 145.4 watts and 1% distortion at 176.6 watts.

There was no multichannel input to measure. THD+N from the CD input to the speaker output was less than 0.004% 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 –82.08 dB left to right and –80.79 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –109.98 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures –0.00 dB at 20 Hz and –0.19 dB at 20 kHz. The center channel measures –0.00 dB at 20 Hz and –0.20 dB at 20 kHz, and the left surround channel measures +0.00 dB at 20 Hz and –0.10 dB at 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is +0.12 dB at 20 Hz when referenced to the level at 40 Hz and reaches the upper 3-dB down point at 96 Hz and the upper 6-dB down point at 116 Hz.—MJP

Thanks for the review. Makes me feel confident I made a decent purchase for my first setup. Unfortunately I live quite far north and the selection is quite slim, and while I could order products over the internet and hope they were decent, I was happy to find this at a retail outlet that I had access to.

One small correction for your article. You mentioned that streaming of internet audio required you to cast the audio from your phone and this is not accurate. (To your credit you did mention that you hadn't actually tried these features and from the outset it certainly seems like this is how it's going to work.)

You do require your IOS/Android/Kindle device to setup the services and channels you would like to stream but at that point you can save them to your favourits list. Once they are setup on the favorites list they can be accessed directly from the receiver and streamed from it. You do not require your cell phone at that point to listen. I have not found a pc app or website that will allow you to log in and setup this same functionality.

Nice review...one small error. I helped a friend buy this receiver a few months and I set it up for him. You can ask Audyssey to only do 3 speakers or 6 speakers instead of testing for all 8 positions, at least if you used the Audyssey app. The app allows you to interrupt the process at 3 or 6 testing positions so there isn't a choice when you first start out.

You state “Denon has in my view abandoned front panel knobs...so don’t lose your remote.” This is truly a bizarre statement. I can only gues that your wife is wearing the pants in your house.
