Worse is later when you realize you never watched the video you went to YouTube for.

You are creating a Front R & Front L channel array. It will give you more coverage. Commercial theatres use speaker arrays to cover more rows of seats.

I believe that boutique processors will allow you to create speaker arrays.

Personally I am beginning to enjoy more and more how Neural X spreads the music in sound tracks across the front to the Fwides and of course with native ATMOS tracks the FWs are used to create objects.

You should compare the 2 setups then decide what is best for you.

Hi all,

I just got the x8500h (replacing pioneer elite SC-LX901 .. which replaced the AVR-X7200WA.. which replaced sc-99...)

Have others bumped into issues where non-HDR video is dimming? I'm not sure when it is kicks in.. everything seems fine.. then.. wait? when did everything get so dark? This wasn't a problem with pioneer nor an issue when the TiVo, xbox x, pc, etc is directly connected to the TV.

I don't want the AVR to do anything to the video. If an upconvert is needed the TV can do it. (it is my understanding the alpha 9 in the LG OLEDs will do better than the chip in this AVR. Is that correct? That said, almost everything is feeding the AVR @ 4k.)
I did shut off the i/p scaler on the AVR and picture mode is off. Video mode is auto (because i don't want game or movie.. both are bad options. I want it to do nothing! ) video conversion is off. HDMI video output is (auto)dual. 4k Signal Format is Enhanced.

Suggestions? It is very odd. The picture seems to slowly dim. So much so that i don't notice it till i look away and then look back. "what? when did it get so dark"

I spend a TON of time on calibration the TV. So in general i don't want the AVR to help, and not helping it dim. It isn't a problem with the TV (unless the AVR is telling the TV something new.) The TV is a LG c8 77" which I've had for like 6 months.

Suggestions? (the wife is yelling at me!)


Thanks
(was the $4k worth it for this AVR? is this any better than any of the AVRs I've had? I can't tell the diff other than it gets real hot.)

If you want 9.2.4 or 7.2.6 Atmos then it’s a solution for you. It was for me.
Cost/price is relative to your money value system.
Real hot, relative to what as you baseline reference temp?

I’ve not seen the non HDR dimming, mines in basement HT with a RS400 projector.

This generally means the unit is poorly ventilated with insufficient open space around it (ie. needs at least 3-4" above with open front/back).

Heat "problem" solved...……...

Not better then any other +9 channel receiver, just has more options and the first that can do without outside amp help for any 7.x.6 setup, and it will do Auro 3D with Surround Back if that's of interest.
I did a trade in with a SR7013 so got it far below retail price but would do a hard think if i needit to pay full price.

Something sure doesn't sound right. I also replaced an X7200 with my X8500. I see no dimming on non HDR content, and I've watched a few movies since I got mine. Also, if it's getting hot, you either need to get some thermostat activated cooling fans ( available on Ebay and many other places ), or something is wrong with that unit. I have cranked quite a few movies to 80 and even a bit more with 13 Martin Logan 4 ohm Motion Series speakers and mine seems to be putting out less heat than my previous X7200.

Check your setup to make sure that video processing is off. Although slowly dimming sounds odd.

Don't stress on the hotness. Coming from a Pioneer AVR (which are class D) … everything is hotter vs that.

the darker picture is the problem

I figure if the case isn't too hot to hold my hand on top of it, it's not too hot (my 7012 has about 3.5 inches above and loads of space on the sides/back/front) in an open style rack. My CPU on my Mac Mini idles at 116 degrees F. It's dumping at 4K disc right now while I surf and it's at 132F. Maxed out with fans on high it's close to 200 degrees. That's HOT, but well within specs. It's been running almost 24/7 for the past 6.5 years with zero issues. In other words, electronics aren't humans. They're designed to run hotter than we'd like to touch (i.e. my 1st Gen AppleTVs were VERY hot to the touch, almost too hot at max and too hot to keep your hand there for long and they still work ten years later (retired now in favor of other boxes).

I have never heard of buffers on the volume control outputs as being a benefit for using external amplifiers. Can you explain? I use a Kondo amp for the main L/R channels.
I selected the Denon8500H not because I needed 13 channels - I actually only run 6 channels! I chose it because of the quality of the DACs and the power supply — these have a big influence on sound quality.

Output buffers are common on higher end consumer equipment and pro equipment. Buffers are rarely mentioned in advertisements or specifications, they are a boring technical detail and not easy to explain. Marantz HDAM's are a notable exception and are well publicized. The buffers serve two purposes: providing an appropriately low output impedance (often 50 ohms RCA, 100 ohms XLR, in pro equipment, higher in consumer equipment for a variety of reasons), and the ability to drive lower impedance loads, that is the buffers have more current capacity, which makes them better voltage sources. IC opamps are the most common.

Yamaha uses output buffers in the preamp outputs in their CX-5X00 series AVP's and RX-AX0X0 series AVR's. These buffers are implemented with IC opamps vs. the discrete HDAM buffers. HDAM's are effectively used to implement opamps with current feedback instead of the more typical voltage feedback.

That said, you are using a tube external power amplifier that has a very high input impedance. The specifications for the Kondo amplifiers list input impedances of 70k to 100k ohms. It is very easy for about any RCA output to drive this high impedance, so you are good to go. For an example of much lower RCA input impedances see below.


While this doesn't relate your installation, there is another side to the high impedances generally encountered with tube equipment. Again looking at Konda equipment, the Konda preamplifiers are rated to drive loads, that is the RCA inputs of power amplifiers, where the power amplifier has an input impedance of 20k ohms or more.

Looking at these measurements of an Emotiva XPA Gen3 power amplifier from Stereophile:

https://www.stereophile.com/content/...r-measurements

The RCA input impendence was measured at between 14.5k ohms and 9.5k ohms depending on frequency. This means a Konda preamplifier, that wants to "see" a minimum of 20k ohms, driving the Emotiva power amplifier is not a good combination. Clearly the Konda preamplifier is designed to drive the 75k to 100k ohm input impedance of a Konda power amplifier.

An IC opamp output buffer (committing the sin of using transistors) could be added to the Konda preamplifier and the output impedance lowered to say 50 ohms. Somehow it seems unlikely that will happen. Alternatively Emotiva could increase the RCA input impedance of the XPA Gen3 to a more typical 30k to 50k ohms.

Very interesting, thank you @bigguyca !

Would be good to know how the DACs compare between the top end Marantz and the Denon 8500.

There's this extremely liquid yet slightly sweet soundstage with the Marantz compared to the sticky toffee sounding Denon 8500.....

(I don't believe any modern properly designed DAC imparts a noticeable sound difference due to the tiny differences involved compared to things like speakers or the room. YMMV)

The "flagship" models (ie. Denon AVR X8500H and Marantz AV8805) use the same DAC: AK4490EQ, while all of the other 2017 and 2018 Denon and Marantz models use the AK4458VN.

The differences are not small. I can readily hear differences between firmware updates on my PS Audio Directstream DAC. But that costs about 50% more than the 8500H...

I think the 7200WA also uses the 4490? I guess technically a 2016 model.

You should consider picking up an AC Infinity unit, that cools my 8500H so that it isn't even warm to the touch.

I'm having issues getting my tv apps to play through my avr. I want to play pandora and spotify from my tv apps. For some reason it's not sending any audio signal back to avr. I can get the cable/sat box to work through avr, but not tv audio.
I have my cable/sat box connected to cable/sat hdmi out. Tv connected to 4k out hdmi. Pc monitor to zone2 hdmi. Is there a setup or button I'm missing?

Technically a 2015 model, but yes, same DAC also on the predecessor "flagship" models as well.

Did you hide the input source for tv audio? I spent a couple of hours figuring this out thinking my 8500 was broken..

No, it's still on the tv (q9fn) I'm just not getting any sound through avr. Should it be on Tv/audio on avr. If so nothing comes out.

Yes, to get sound from the TV into the receiver you must select the "TV/Audio" input in the receiver, but that's just one of several settings which must be configured correctly.

ARC can be problematic. Many people use a digital optical connection instead.

Some things to verify:

Make sure that the receiver's HDMI connector Monitor1/ARC is cabled to the TV's HDMI connector which is labelled "ARC". This usually is not the TV's HDMI1 connector. (See page 83 in the AVR-X8500H's owner's manual.)

Make sure that HDMI cable is "Certified Premium". Some cables labeled "High Speed" might work, but many are unreliable for 4K video and audio. "Certified Premium" cables cost no more than High Speed cables.

Make sure both CEC and ARC are enabled in the TV. Samsung calls CEC "Anynet+".

Make sure ARC is enabled in the receiver. CEC and "TV Audio Switching" are not necessary in the receiver, but might be appropriate depending on how you use your system. (See pages 198 and 199.)

All of this is already set this way. I am not sure if the ARC is setup in the receiver though. I will double check.

I don’t like to change gear often. I kept my last receiver for 11 years, and plan to keep the 8500 for at least the same amount of time.
DAC technology changes quickly, however. And despite what some think, you can hear differences among DACs. Much like buying a PC that you intend to keep for 3+ years, I wanted to buy the best and latest DAC tech. That’s why I was asking.

My interest is in the DACs and how they are configured, for example the 8805 I believe uses 8 of them in stereo mode. There's another flagship in the same price range (the Emotiva rmc-1) using the 4490s in differential mode, i.e. one 4490 per channel.
