The AVR: Denon X3400H

The choice of AVRs used to be a difficult one to make when support for different HD audio formats was not widespread. Now, the requirements boil down to the AVR being able to support the latest HD audio formats (Dolby Atmos and DTS-X), while matching the capabilities of the display in the chain. The additional features may help sway the purchase decision for consumers.

Budget considerations dictate the number of channels and display zones. We had to migrate from the 7.1 channel Pioneer Elite VSX-32 to a newer receiver capable of handling multiple HDMI 2.0 / HDCP 2.2 inputs with passthrough capabilities for various HDR formats. Based on my budget, I narrowed down the options to one of the models from Denon, Onkyo, Pioneer, and Yamaha. They are all in the same ball park in terms of pricing for a given feature set. We deferred to our friends at Wirecutter, who recommended the Denon AVR S730H.

I had been in touch with Denon regarding HEOS (their whole home audio solution) when the decision to go with a Denon AVR for our HTPC testing setup was taken. Upon discussing our project with them, Denon graciously agreed to sponsor the more advanced AVR X3400H for use in our testing.

The AVR X3400H targets the custom integrator channel. It has a number of additional features such as support for high end DSD audio, 4Kp60 upconversion for analog sources, multi-zone video outputs, higher power output, and support for eARC (Enhanced Audio Return Channel) to justify its higher price over the S730H. The presence of eARC makes it a bit more future-proof, as it allows for HD audio (including the new ones like Dolby Atmos and DTS-X) from the display sink to be returned to the AVR for decode and playback.

In the course of our testing, we found that the AVR received frequent firmware updates to add new features such as HLG passthrough. These point to a well-supported product. Even though the web control feature present in the previous generation Denon AVRs was missed, the Denon AVR Android app made up for it to some extent. None of the issues encountered in the course of the evaluation presented in this piece could be attributed to the Denon AVR X3400H.

If we had to give some suggestions to Denon for the improvement of the AVR X3400H, it would be to bring back the web control feature and shorten the time taken for firmware updates (though there is a facility to enable auto-updates that tries to install the new firmware when the AVR is not being used).

Speakers

Most readers upgrading their HTPC can opt to retain their existing speakers. In fact, I had the Boston Acoustics Horizon Series MCS100MDNT 5.1-channel speaker system from a 2008 purchase, along with a Jamo A306 HCS 5.1 speaker system from my 2011 home theater components upgrade. However, due to the remodel, I had to go in for in-ceiling speakers. I opted for a couple of the Polk Audio RC80i in-ceiling pairs for the rear and surround channel speakers. I bundled them along with ceiling speaker protective covers. The choice of speakers depends on the home theater size and other requirements. Currently, I am using the Jamo A306 speakers for the front, center, and subwoofer, with the Polk Audio RC80i for the other channels.

    I would really much like to listen to your setup, sincerely. I know I would be in awe, never said what you put up on the internet is pure crap, all I wanted to hear from you is that there's stuff out there even if it's overpriced, includes DRM, seems like pure mockery that can still be liked by someone even if it seems impossible to you.

    But you are such a supreme being with no space around it for tolerance of imperfections in the current world

    "Sennheiser HD-800 and Hifiman HE-560 running into a burson conductor SL1793 and I know how a recording should sound. My stereo setup consist of Rega Elex-R and ATC SCM 19 v2."

    You poor guy
    You've never actually heard a great set of speakers
    Even your headphones begin combing over 10Khz with a sine sweep

    My Speakers have zero combing or image shifting at any usable frequency

    Image is stable at ALL usable frequencies! and the sweet spot covers the entire room unlike your ATC SCM 19 v2

    Phase coherent hybrid crossovers and full omni-directional imaging would probably scare the crap out of your after being stuck with your Low End setup for so long

    You have my sympathy

    Well happy to you if you got the most neutral stereo system in the world, never said mine was perfect but it's still good enough to know how a record should sound even if it still has coloration. I was already informed about the bump in frequency on my headphones, the frequency graphs came with the headphones.

    Who do you freaking think you are, I just said I've seen people liking lower end system than higher end ones. What you want in the end, it is not nature with it's imperfection, you want the perfection humans have created, you wanna hear mathematics perfectly aligned, let's kill all those unbalanced beings and create a planet where everything is robotized, controlled, calculated.

    I like imperfections and you seem to believe no one should, I never said you can'T like what you do. I'm trying to have you understand someone else might very much like what you find disgusting. You have yet to understand that.

    ''You've never actually heard a great set of speakers''

    How condescending you can be, I went to many audio shows including Montreal audio fest, again I guess every set of speakers there was really bad, everything is to you yet you recommend stuff like JBL powered speakers which by the way must sound uber crappy. I'm not trying to win a contest here, you already won the internet sir. You own the very best the planet has to offer and yet you can'T accept people can like stuff even if there's better out there.

    My crap low end system, let's then not consider 99.9% of speakers ever produced amplifiers and so on because they're all crappy colored and unworthy.

    Those JBL speakers you recommended are crap btw you just said it. No one can like them. That behringer 2496 can't be loved either, it's crap by your standards because you own better, everything below what you own is crap and then should not even be discussed on the internet.

    I never tried to show you I own better than you, I just wanted you to aknowledge someone might like what you dislike, audio is not science, it goes through someone's ear and then is interpreted by their ears. A neutral sound set of speakers will make some recordings unlistenable. If those records are 90% of what they listen to, they will hate your super neutral sound system.

    Forgive them for they know not what they do.

    I'm sorry, I forgive you, let's hope you will be able to do so with me.

    "My Speakers have zero combing or image shifting at any usable frequency"

    You are talking about the JBL LSR305? Even if that were true (which I doubt), there are many many other significant aspects of loudspeaker design. Some simply cannot be properly addressed at the price point of the LSR305. For example, it can be assumed that the drivers of the ATC SCM 19 v2 will have significantly better distortion / linearity specifications that the cheap drivers in the JBLs. And although powered speaker can be very good, I wonder to what extent JBL addressed vibrational effects on the internal amps and crosover considering the available budget (All amps and even crossovers are microphonic to an extent). So much more could be said.
    I have heard neither the JBLs nor the ATCs, but logic dictates that if the JBLs are even remotely comparable to the ATC in sound quality, then JBL truly pulled off a miracle!

    Oh HELL NO!
    I am definitely NOT talking about the "BUDGET" JBL LSR305 Home Theater setup

    I was referring to the 3-channel "Reference Standard" speakers I created over 30 years ago

    Additive/Subtractive frequency interference is easy enough to eliminate with a 3-channel system when done right, but cannot be eliminated in a 2 channel stereo system regardless of cost

    You will get ALWAYS get combing whenever you send the same signal to 2 or more speakers simultaneously

    Even the most expensive dynamic headphones exhibit image shifting at higher frequencies

    It is much less noticeable with planar magnetics, but still there

    You can easily test this combing effect by runnin a mono sine sweep into your headphones at a low level to protect your hearing

    The sweep (Starting at the bass end) will remain dead center of your headphones until it reaches a certain frequency which could be 6-8 Khz on pure crap headphones / 8-12Khz on most midrange headphones and above 12Khz on the best available headphones

    Ideally, you do not want the stereo image to shift left or right as frequency changes as the stereo image wanders and muddies up the acoustical image you are trying to create

    Hahahaha! Someone skipped a dose?

    @ddriver, this is very low end for me, so I have no issue with it being called budget. The Jamo sub is utter crap probably not even worth $100 if sold alone. If this build had say a SVS PB-1000 as the sub I might be onboard on the sound side. The in ceiling speakers are at least middle of the road. The other tips were nice but as far as the speakers go it couldn't be any more low end. I ahve the Denon AVR x3300 the prior year version of the one here and it is a lovely receiver mostly because of the Audyssey xt32.
