Denon's days of grifting a full $1700 retail for the X3800H are numbered.
Wouldn't count on it. Plenty of people will be willing to pay more for a Denon. Downward price pressure is always welcome, though.
 
Wow. That's the killer app right there for anyone not needing 7.2.4. New with full preouts, Dirac, metal faceplate, buckets of 12V triggers for $750? Bested perhaps only by Best Buy selling the VSX-LX505 for $999. Open box (no shipping) cheaper, but will come with full mfr warranty. You get 2 extra processing channels but less triggers. And these Onkyo have a significant benefit in that the pre-outs measured very clean up to at least 2V without shutting off the amps. That's potentially a big deal if you want to use any of the internal amps, which you will, and need to crank it up to get that last 3dB. And the best part with BB is that if you hate it, the return is really simple. I can't believe how cheap these have gotten. Denon's days of grifting a full $1700 retail for the X3800H are numbered.
I have one, and I have difficult to drive 4 ohm speakers (dropping down to a low of 1.6ohm) - the DRX 3.4, works as a superb prepro for the hard to drive front L/C/R via external power amps, meanwhile I save on space and costs by using the internal amps to drive the rears and heights.... my setup is 5.1.4.

Results have been excellent - Dirac also contributed to the end result noticeably.

YES - the DRX 3.4 driving my fronts sounded sub par - the internal amps were NOT up to the task of driving speakers with a 1.6 ohm minimum... but the pre-out's are good... and I have susbtantive amps to handle that task - and the internal amps did handle the rest of the speakers with ease.

Also, the unit runs very very cool - unlike previous generation Onkyo's & Integra's that I have owned - which bodes well for a long service life.
 
Let me make this clear:

For the second review, when I got to the power test, the AVR limited power. No test prior to that pushed the amplifier to the limit that I am aware of. This is not a rigorous statement but that someone needs to test for this with a unit out of the box and prove that it is not getting triggered due to other factors such as heat.

Next time I get such a unit, I will test power immediately to confirm what is going on here.

For now, the major fault is lack of indicator in the front panel. If they fixed this with firmware, then everyone would be able to check and report how prevalent it is. I would push Onkyo/Pioneer on this with the hope that they listen and make this change. If this is related to passing UL testing, I suspect this will never come to pass. Thinking out loud, maybe we should contact UL and see what they have to say!
 
This is a review and detailed measurements of the Onkyo TX-NR7100 8K 9.2 Channel THX certified Audio/Video Receiver (AVR). It is on kind loan from a member and costs US $1,099.

Not much departure from the classic look of AVRs in the last 30 years. The on screen interface has been enhanced to be high resolution and is responsive. While some parts of it are intuitive, others are not. Options are grayed out at times with no indication as to why. For example I wanted to turn on Zone 2 audio but the option was gray. Reading the manual revealed that you have to first enable Multizone option to get access to that. I updated the firmware over the air and that went well. But when finished, it just told me on the AVR that the update was completed but then sat there locked up requiring a power cycle.

Back panel shows the puzzling inclusion of analog composite and component video:

Onkyo TX-NR1700 Measurements
There is no pre-out so I could not test the performance of the main DACs. There is zone 2 so I went ahead and tested that:

View attachment 386237

The high level of distortion is embracingly poor if it is any indication of how the main DACs operate. For the rest of the tests, I went for full end to end performance starting with HDMI input:

View attachment 386238

This lands the unit next to its sister models from both Onkyo and Pioneer:
View attachment 386239
With most of its competitors in the "Green" category, this stagnant performance is not good. Performance is naturally similar with Toslink input (used for later tests):

View attachment 386240

Notice the noise variations to the left of our main tone which is absent when we use analog input:
View attachment 386241

Noise performance is in the same "fair" category, not reaching the target of 16 bits at 5 watts:
View attachment 386242

If you use direct/pure direct, system bandwidth is wide and flat as you expect:
View attachment 386243
If you do not, response truncates down to just 20 kHz (not shown) indicating everything is resampled down for processing.

Multitone has high noise floor and same ho-hum performance.
View attachment 386244

Same with 19 and 20 kHz intermodulation test:
View attachment 386245

Power testing is what got my blood pressure to shoot way up. Ran the sweep and got just 40 watts or so! I remembered the power limiting I had seen in previous units from Onkyo/Pioneer but had forgetting the cause. I updated the firmware and power cycled the unit as mentioned in introduction. I got full power then, remembering that if these units ever clip, they will stay in ECO mode of some sort until you remove the AC cable! I didn't recall the unit clipping however in this case. Here is 4 ohm test:
View attachment 386246

The 1% THD test pushes the amp into clipping often which meant it took a lot of effort to get the right measurement data:
View attachment 386247

Here is 8 ohm:
View attachment 386248

I let the power sweeps vs frequency clip and there, you can see the sudden power limiting as sweeps go from 15 kHz down to 20 Hz:
View attachment 386249

Note that there is no indication whatsoever that this mode is activated! The amp simply stays in this mode producing only 15% of its rated power until you power cycle it (it does NOT reset with power switch).

Conclusions
The TX-NR7100 delivers "OK" performance across my tests. The problem as I have noted in previous reviews of this shared platform between Onkyo/Pioneer is this severe power limiting mode. I have to think it is there to pass UL regulatory tests and hence the reason it doesn't even tell you that it has gone into this "limp" mode. Naturally there is no mention of it and even searching online won't clue you in this problem.

Based on this testing, I suspect many users are experiencing a fraction of the power this AVR is capable of without knowing it. Detecting/proving that it is doing this requires power sweep measurements which is outside of the abilities of almost every user of this AVR.

For above reason, I cannot recommend Onkyo TX-NR7100 AVR or frankly, any AVR from Onkyo/Pioneer until they address this power problem.

I have a Pioneer VSX LX 503. For all that has been said about its platform, is a cheap AV receiver for a room up to around 20 square meters on moderate volume. I use a stereo amplifier for LR channels. Never ever dream to plug a 4 Ohms speaker on it. On this arrange, it is honest for its (old US$ 549.00) price. A 505 model at US$ 1,000.00 does not worth, IMO
 
AVRs aren’t focused on image processing, they don’t do anything to it other than the option of an upscaler. Adding the HDMI 2.1 port doesn’t mean it’s about “image processing”. Also, 2.1 is useful for 4k/120hz gaming, which may be its most used feature. There are some people that buy 8k tvs, but I mostly hear 4k/120hz being the main goal of getting 2.1. That’s why I upgraded my pre/pro with the 2.1 board too.
It is true that AVR is not processing graphics, but support for ultra-high-definition movies and games has become the core selling point of AVR.

When talking about sound quality, it's always on the last page. Now the AVR price is very high, it is true that it has supported all kinds of ultra-high-definition picture quality, but the audio quality is far behind the desktop HIFI device.

Considering the price, quite a few AVRs are not worth buying at all, because the lowest AVR now supports 8K60hz, and a few times the high price is only a little additional features.

And pretty much any other Android/Google TV player capable of running Kodi, VLC or some other similar app? :D
And none of which are HTPCs.
Which is what besides the shield? There is no popular device that people are using to play media on outside the apple Amazom chain. You either are using an htpc, a shield, or some nameless media box. There is one company zipedea..something like that. Oppo is gone. There are only really a couple of decent 4k players on the market. Locked down corporate streaming is the new normal. They will stop producing discs soon because the younger buyers don't use the players. Grandpa is the user of HTPC now. . I remember how awesome getting a graphics card with hdmi was.

Many folks also forget that w/these mid-tier Onkyo/Pioneer/Integra AVRs that come w/Dirac, a license fee has been paid to Dirac for the privilege. However much they paid Dirac is that much less money spent on hardware! Yes, the Denon 3800 and kin are more expensive but they have a dedicated SHARC DSP chip that can go all the way to processing DLBM. Just ask Onkyo 7100/RZ50, Pioneer 305/505 (and presumably Integra DRX 3.4 and 5.4) owners why it takes so long to transfer the Dirac filter and why it's not capable of DLBM/DLBC! Having Dirac Live "included" doesn't mean Onkyo didn't cheapen out somewhere else!

For my LX305 it is about 9 seconds for preparing export and 8 seconds for transfer. It is for 4.1.2, maybe would be more for 7.1.4. IMO it doesn't depend on DSP but internal microcontroller.

Similarly for DLBM/DLBC. All calculations are done on PC and DSP doesn't get much more work than for standard DL. If you can't buy DLBC, then it is probably marketing decision to make you consider RZ70 and spend more. DLBM seems to be a special case for AVR with multipe subs, where it replace DL.

And I'm sure, that Onkyo did a lot of cost savings, regardles of DL :)

I've seen a lot of complaints concerning HDMI w/Onkyo units but not from personal experience as I haven't owned an Onkyo since the TX-SR601!

This is not a rigorous statement but that someone needs to test for this with a unit out of the box and prove that it is not getting triggered due to other factors such as heat.

There are undoubtedly separate thermal and possibly a peak limiter. I suspect for this particular limiter, Onkyo likely just samples the rail voltage with a time function. The receiver may not care if there is current actually flowing. The amp "knows" it cannot supply the hypothetical current being demanded without an eventual thermal event or PSU failure, assumes it will continue since it has already gone on for 35 seconds, and permanently latches to a low rail. More or less, it may be a failsafe to the thermal limiter which will still activate and trigger even if the thermal limiter fails. Since the power amps do not disconnect, something as simple as hitting it with a 2V input signal for 35 seconds with no load connected possibly could force the amplifier onto the lower power rail until a power cycle. I would not be surprised if the AP SINAD dashboard could trip it if left to run, even with a zero current demand. I believe D+M products used to do this as well, but might be wrong on that. Whether this particular limiter is hardware or software, who knows.

I am an AVR meathead (someone else in this thread coined that term). I purchased the Onkyo TX-NR-7100 last May. This is perhaps the best AVR I've had in my man-cave in 20 years. The features are fantastic, DIRAC is a game changer for my room. It's a 9.2 channel AVR, perfect for me. I use the AVR primarily for Movies and for 2-channel music via CD and streaming a distant third. I'm a baby-boomer so I don't turn the volume as high as it go, but I can rock out if the feeling moves me. The sound characteristics of the Onkyo TX-NR7100 are very good with my Klipsch speaker 5.1.4 setup. I have a highly technical job and background and I'm very comfortable with measurement techniques and results as described on this website. I am fan of this website, not so much the comments from others. The quote below is from the Amirm's website on this AVR, I'm not kidding!
One of the typical examples why I won't buy an AVR any time soon.


As a consumer grade customer who has a budget to keep in-line with other priorities I simply adore the sound in my room. I doubt I will ever have a problem with the power output the the Onkyo 7100, who would unless your a person under 30 yrs old trying to impress the neighborhood. I get it this AV receiver doesn't come close the specification of a product 2-5 times the price. Should it? I can simply say, if you are a consumer like me, in my age group, and not audiophile, BUY the Onkyo TX-NR7100. For $800 (on sale). OMG it sounds awesome! I'm not being a audio SNOB. Don't get me wrong, I absolutely LOVE the writeup that Amirm produces on his site.

AVR Meathead
 
I still say there seems to be a huge disconnect with many members here, based on what they expect to get for this price range.

Top Notch performance audio and video, along with 5/7/9 or more channels of amplification, tons of switching, room correction, equalization, and many streaming features and wifi stuff, Remote controls, etc, etc simply can not be had for a lowly $1,000 or so.

I have seen 2 channel amps that cost as much as more as THIS!

VERY UNREALISTIC expectations.............wow.

To do all this with complete separates and have ALL THE FUNCTIONS of this or a similar AVR, would be literally $5,000-7,000

All Avrs based on price alone MUST be a compromise, between tons of features and connections and so on, and less than ideal 4 ohm performance and some power amp limitations.


Not excusing how this one in particular implemented the protection, but I am just wondering what some are "Expecting" for about $1,000??

I try to have the best low cost possible set. For music, an old Sansui AU 317 is fantastic, much better than the Pioneer VSX LX 503 itself. I could use Pioneer’s preout to the Sansui, but an used Mac Mini with Audirvana and TIDAL/Qobuz and a Topping E50 DAC sounds slightly better for me. Talking about US$ 1,500. set, if you buy used some components. Amazing results.

For $1000+, yeah I expect half-decent engineering. There are AVRs in this price category that do.

You can get very high performance 2-channel amps for about $200 nowadays, btw.
 
Which is what besides the shield?
Chromecast with Google TV will be an obvious answer if you need a huge brand name but there are TONS of Android TV devices on the market from, probably, hundreds of different (mostly unknown, but who cares?) brands, even Walmart has its own Google TV streamer (for < $20, https://www.walmart.com/ip/onn-Google-TV-4K-Streaming-Box-New-2023-4K-UHD-Resolution/2835618394). Shield is just one of the most capable (and most expensive), doesn't mean people need it. I own several Chromecast with Google TV devices and they play media from NAS without any issues.

That will do 120 watts at 8 ohms and 150 watts into 4 ohms>??

I really do not know, not challenging you. Have not been in the market for an (new) amp in many years.
