    The flagship that's supposed to rival the old Denons of yore..

    The official website:
    AVC-X8500H

    A video explaining the major bits:
    First preview of the DENON AVC X8500H Amplifier


    Start watching around 10:00 for the AVC 8500 information.
    27kg!
    Thick panels !
    Copper plates around the power section.
    Griffin Lite 32 bit DSP chips!
    32 bit up-conversion:
    ADSP-SC58x and ADSP-2158x Series | Analog Devices
    Around the 25:00, the video says it can consume 2800W to power all 13 channels ... [​IMG]

    Some important info from audioholics:
    Denon AVR-X8500H World's First 13.2CH AV Receiver Preview

    What does the AVR-X8500H Offer Over the AVR-X6400H?
    • 13 amp channels vs. 11, and 13.1ch processing vs 11.1ch max on the X6400H.
    • Higher power rating (150W vs 140W into 8ohms, 2CH driven).
    • Physically larger (about an inch taller, two inches deeper, and quite a bit heavier). The user manual states it weighs a whopping 51.4lbs despite the website error showing 39lbs. we confirmed with Denon at CES the correct weight is stated in the user manual.
    • 15.2ch RCA pre-outs vs. only 11.2 on the X6400H.
    • 15 pairs of speaker binding posts vs only 11 on the X6400H.
    • The above facilitates the ability to run BOTH a 13ch Auro3D setup and a 13ch (9.1.4 / 7.1.6) Atmos setup without having to ruin positioning for one or the other. Because there are FOUR pairs of height speaker outputs (pre-out and speaker posts), with flexible assignment (including being able to assign Height4 to Front Wide output) you can do a complete Auro3D setup with five heights + VOG and still have another pair of height outputs for Top Middle or Front Wide use with Atmos.
    • The X6400H, of course, can only do 7.1.4 (no wides) and is limited to 10.1ch Auro3D (5.1 + 4 heights + VOG). And the only way to practically mix Auro + Atmos is to use a Front Height + Rear Height layout. Plus the X6400H requires you to sacrifice the Sub2 output for VOG if you want to do 10.1ch Auro3D, whereas the X8500H has dedicated outputs for Center Height and Top Surround (VOG).
    • X8500H also has a "Custom" amp assign setting which allows you to map virtually any speaker binding post to any channel of output. For example, if you're using a 5ch amp to power LCR+Surrounds in the main zone, you can repurpose the unused FL/FR and SL/SR amps in the AVR to power Zone 2/3 speakers (the X6400H only has predefined templates for amp assign).
    • The X8500H also has a "pre-amp mode" which disconnects the amp section.
    • 7.1ch multi-ch analog audio inputs, extra (3 vs. 2) component video inputs.
    • Future HDMI 2.1 hardware upgrade to increase lifespan by supporting 8K resolution and more (the same way they offered the "A" upgrade to the 7200/8802 for HDMI 2.0 in the last generation).
    • The X8500H has different DAC's specified, it lists the AKM AK4490EQ for the X8500H and the AKM AK4458VN for the X6400H. A quick check shows 5dB increase in SNR for the DAC in the X8500H
    • The X8500H can do a vertical stretch for use with anamorphic lenses.
    • X8500H has a rear USB input in addition to the front USB, the rear port is rated to power devices so more practical for a streaming stick or cooling fan etc.
    • The X8500H has a nicer remote with "learning" capabilities to copy IR commands, macro capabilities, and also a "Remote ID" setting so you can prevent conflicts with other Denon device remotes accidentally changing it.

    Sweet! What speakers' setups are you planning to try/test?

    It should be available in Germany in ~10 days and I'll get it right away.
    Can't decide yet if I'll go for the front wides or 6 upfiring channels though...

    Looking forward to your review!

    Damn that looks good. Totally, totally over the top for the rest of my kit, especially now as my fronts are driven by a Rega Elicit-R, but I so want one.

    You can see my current setup in my signature.. I use the Dynaudio Confidence series. These are 4 ohm designs which should give them a real workout :)

    More on the goodness inside:

    "Denon AVC-X8500H Amazon Alexa
    The manufacturer also introduces a new design for the X-Series with the Denon AVC-X8500H. The amp case features a solid aluminum front panel, a reinforced topcover, two separate side panels, and a two-line display that comes from Denon's NE stereo series. The interior is dominated by a centrally arranged, voluminous transformer in addition to the 13 output stages, which are arranged in monobloc construction right and left of the toroidal transformer.

    Denon will also release the eARC (Enhanced Audio Return Channel) via a future free firmware update. This allows HD and object-based audio (Dolby True HD / Atmos / DTS-HD / DTS: X) to be transmitted via an HDMI connection to the compatible TV or TV apps.

    Another update (expected from early summer 2018 in Germany / Austria) should also unlock the voice control Amazon Alexa."

    Denon AVC-X8500H connectors
    Vinyl enthusiasts can look forward to a phono input, while digital players will find their way to eight HDMI inputs with full HDCP 2.2 support.

    Three HDMI outputs allow the parallel use of a TV and projector in the main room and the additional use of another HDMI output for a second zone.

    The digital feature set is made possible by a fully redesigned DDSC HD-32 digital section, which features two brand new 32-bit dual-core processors from Analog Devices. A total of eight 32-bit stereo converters are responsible for converting the digital signals.

    Hmm
    I can't find absolute proof yet but it seems that the 8500 only has 44000uf of capacitance.. that's the same as the 7200 and 8012 ...

    Surprising, if that's the case. The older 10Ch AVC-A1XV(A) had 132000uf.

    To be fair there is only so much they can cram into a single box no matter how heavy it is.

    I wonder whether manufacturers would be better off making a sort of hybrid receiver/processor with a separate power amp option: Maybe put some lower powered amps in the same case to cover height channels and have an extra box for the main channels. Make it configurable so that it could be used for basic 5.1 use on it's own while you save up for the power amp.

    Every slide I have seen shows two 22000 caps. Unless it's just an illustration, it's a bit disappointing. It can be an industrial decision since you use off the shelf parts that are shared amongst a few models.
    The same caps are used in the marantz pm11s3. And that toroidal could be the same one used in the 8012.
    Three of them makes it uneven but to have four giving 88000uf is a tad hopeful...

    I made a little table of the differences between the 8012 and the 8500:
    There are probably more, but I hope this helps those who are consider the two models ..

    There's been some good hands-on discussion on the 'other' forum regarding actually working speaker and decoder combos. It is shiny but I'm thinking maybe waiting for the A version rather then the pain for sending back for the upgrade.
