Denon AVR-X4700 AVR Review (Updated)

Haha, same to you I guess. The 5200 likely has a stronger power amp section but the 4700 has better preamp/dac so if used in preamp mode it should be better in sq based on specs and measurements.
If used as avr, I would bet on the 5200 but would expect the difference to be subtle.

Hi folks
I have had an issue with my Denon AVC-X4700H in the last 4 weeks, speakers suddenly making a loud popping sound and then going into protection mode (flashing red light) with the Audyssey setup screen then appearing on my TV and the units display
I did a full factory reset, unplugged everything and it hasn’t done it again.. checked every speaker cable, every HDMI, etc etc
How can a factory reset fix my protection mode issue? Or will this issue return ?
or if anybody else has this issue, what was causing the issue or fault ?

I then recalibrated everything on my iPad using the Audyssey app
My AV receiver was bought December 2024 from Richer Sounds in Oxford, it was a “trade in” item
They refuse to help fix it
My system is as follows
2 x Front floor standing speakers
1 x centre speaker
2 x upward firing Dolby Atmos speakers
(Sit on top of my floorstanders)
2 x surround speakers
1 x Subwoofer
all Monitor Audio Bronze 6G Speakers but with a BK Electronics Subwoofer
65” LG C4 OLED TV
Since doing a full factory reset and recalibration with Audyssey app on my iPad, my Denon 4700 going into protection mode and making that popping sound has not happened in 3 days and I’ve had the amp running lots in this heatwave in the UK
how can a reset fix the issue?
I was thinking of upgrading to a 4800 model but is that actually worth it? Is it a better sound?
I only have the following stuff in my setup
LIVING ROOM SETUP
65” LG OLED C4 Television
Amazon Fire TV Cube 3rd Generation
Denon AVR-X4700 AV Receiver
Van Damme Hi Fi Speaker Cables
Monitor Audio Bronze 500 Floorstanders
(For Main front speakers)
Monitor Audio Bronze C150 Centre Speaker
Monitor Audio Bronze 100’s on rear brackets
(For rear surrounds)
Monitor Audio Bronze AMS Dolby Atmos Speakers
BK Electronics XXLS400 FF Subwoofer
Panasonic DP-UB820EB Blu Ray Player
Pioneer BDP-180 Blu Ray Player
Marantz CD60 Silver CD Player
Sony PS4 Pro Games Console & Games
First, the AVR should be placed such that it has sufficient ventilation, especially if running at higher room temperatures like 26 or 27C, which would be temperature expected during heatwave with no AC. It gets worse as heatwave lasts for days - in one of my flats without AC temp gets to 30C.
x700H generation runs pretty hot so placing some fan unit on top might also work to avoid overheating.
4800H has 4 sub outputs and Dirac capability which are usually biggest reasons to upgrade. Not sure if you fancy any of that as otherwise there would be no fundamental difference. Dirac ART is considered as most advanced auto EQ system and yes, it sounds excellent compared to Audy.

It’s currently 29C in my living room
The unit has no obstructions around it
Loads of room to breathe
Thanks, well, the made in Japan 5200 seemingly has the same power amp section as the 7200. I don't understand it either, but when I got the 4700, the sweetness of music and film scores just wasn't the same, and I set the 4700 up as identically to the 5200 as I could. I wish I had never gotten rid of it. I don't think the 5200 had an actual pre-amp mode, but I did use the front L/R pre-outs and separate amp, just as I do with the 4700.
The sound of my 4700 is very good. It’s a model before the akm factory fire happend.

When I switched to Front Preout the heat of my 4700 was much lower. At the moment I’m going full preamp mode. Now Heat is mainly coming from the videosection but not comparable with the heat coming from the amps before. This, my AoIP goal and amir’s measurementes convinced me to do the switch to full preout.

Well, 29C is a lot. No other suggestions except the fan or fan unit.
These are considered as very good.

I do have one of them on top of my 6700H as even in pre-amp mode don't like the temperature even in 24-25C room. Never went into protection mode.
You might be one of those who are very sensitive to subtle sound quality differences. The fact is, the 4700's power amp section is a little difference, it is basically same as the midrange Denon and Marantz AVRs but the X5200W was the flagship at launch time so yes it has the same design as the X7200W and the subsequent flagship X8500H and the X6700H, Marantz SR8012 as well.
Also factual, the x4700h preamp/dac has D+M's first (still is) dedicated volume control IC that is used from the 3000 series (not sure about models below that) up the flagship models, and it has the so called velvet sound AK4458 DAC IC (unless you have the models made after the spring of 2021 when D+M switched to the PCM5102A that has inferior specs. It is possible that you may like the SQ better if you use the X4700H as preamp/dac only, or at least use the LCR pre out with a 3 channel power amp of your choice.
The AK4458 DAC has much better SINAD spec than the PCM1690 the X5200W uses.
Thanks. Yes, I have a Parasound A21+ for the front L/R speakers and an Outlaw 2220 for the center speaker. But I drive the surround channels with the 4700.
Thanks, then I don't know why the 5200 would sound better, the only other thing I can think of is the DSP, that are obviously different but that won't affect SQ when DSP are not used.
It's easily possible the old Audyssey curve was asking for a too demanding correction (boost) to a dip in one or more room modes.
Without seeing a graph of the two corrections it's impossible to say for sure.
I highly recommend adding some additional cooling in the way of fans, you can never run them too cool and seeing your indoor temp posted, that's
tuff on the gear. For around $35 you can buy a Noctua 140mm computer fan and set it on top of the AVR, blowing up. I use the supplied speed dropping resistor and
the rubber pads on the corners stop any vibration noise, I can never hear it. Same fan is now on top my Marantz AV20
Here's a photo of mine on top of my Denon 4700
Same one on top of your AV20 - no wonder you don't want to share photos with AV20 in place. That is one highly effective but really ugly fan.
But why would you need fan on AV20 - I would imagine you use AC so don't have 29C temperature in the room? Even with that, I don't think AV20 would really cause any trouble if in well vented spot.
Ah well, beauty is in the eye and all that.
Still I thought the AV20 was surprisingly hot for a pure pre-pro.
My 4700 was about the same and always used in pre-amp only mode.
Fan was on top my 7703 too.
You can never run too cool.
My feelings are crushed.
I suppose you think my room treatment is fugly too ?
Cmmon, can't crush the Chicago Crusher (BTW explaining that title could be a good story).
No comments on the room treatment, they actually look cozy. But still not sure why your AV20 is running hot. I have AV10 in standard rack with not much clearance as it is a bit of a beast, but it really only gets warm at times. In the summer, I do run AC so the gear tends to run at 24 or 25C, not more.

Seriously, "hot" is subjective thing, maybe warm would have been a better adjective.
My room temp is around 80-81f mostly year round.
In any case I still feel you can never keep your gear too cool, all my amps and 85" video have some additional cooling supplied.
JMHO.
Better to be safe than sorry of course. But that Chicago Crusher story remains to be told...My badge is just Oddball which does not need much explanation. Dog is lazy and penguin is really annoyed if not chilled down. A terrible combo.Seriously, "hot" is subjective thing, maybe warm would have been a better adjective.

That handle was laid on me by our first moderator here Thomas Savage. He thought it fit my writing style and attitude best. LOL
That explains it - many thanks. But I find your arguments quite alright nowadays. I guess I am going for the title Zagreb Crusher if they ever are inclined to award it to me.
