I have for a long time used a computer 240mm fan with the rubber mounts sucking the hot air off my AVR.
I have a Marantz and have filed this comment away for future reference...if it's a modern Marantz, I recommend checking ALL of the cables, cause that happened to me this year and I broke down and got a Tonewinner combo similar to THIS ONE , which, I will say , kicks ass; but I plugged all my stuff to it and it shut itself down AGAIN, so I went cable by cable and found out that the culprit was an RCA cable that had gone south!!!!
My Marantz SR7013 at a closeout price of $1600 was a better deal. Same power output, Atmos, Auro 3D, etc. But only 4k switching on the 7013 vs 8k on the 7015, and perhaps one or two less bells and whistles.I own a McIntosh MX122, starts every day, plays everything, hope it lasts forever.
In a open shelf.
My Fanless PC that I use, hooked to my external MCH DAC, that RCA's back to the 7.1 RCA section of the McIntosh, again starts and stops, every day without a problem.
A friend of mine came over very impressed with the whole surround and sonic quality of my home rig. We did some internet shopping and we came up with what I thought would be very good for him and his budget.

I am also a retired electronics engineer / technician & agree with the above that cooling electronic devices is the best way to a long life. Most of my AV receivers have small fans that I have installed to keep them cool & they seem to last forever that way.My Marantz becomes a room space heater when operating even at modest volume levels. Excessive heat will dramatically shorten the life of any electronic component, especially a device as complicated as an AVR.
That said I find that an EXTERNAL cooling unit is almost a requirement for today's multichannel receivers. I burned through several before I wised up.
My Marantz has been running problem free since 2018 with this cooling it.

Anyone who has been in this hobby for more than a year or two has experienced hot components. I started with tube gear, so room heat in the winter wasn’t an issue.My Marantz becomes a room space heater when operating even at modest volume levels.

The AVR that I found that was reasonably priced, with great reviews, and the ability to have up to 7.4.4 Atmos setup with up to 4 separate subs (CRAZY!) is Denon's 9.4 AVR-X3800H, which still boasts 105 watts to 9 channels. Not quite my 140 W/channel to 7 channels of my Yamaha, but pretty close and 15 years newer technology, as well as the ability to play ALL current surround technologies available, at a reasonable price of $1675.00.

The reviewer and the early respondents seem to be disappointed mainly on the basis of the bench specs, which are worse than the 3800H's predecessor. I didn't have the patience to read through more than a few of that thread's 80(!) pages, but I'm wondering how those specs translate into audible differences and (@ArmyOfQuad's main concern) reliability & durability. Any thoughts about that, @nikomen?Here's a pretty comprehensive test/review on the X3800H:

I’d assumed you could simply bitstream 360RA from Tidal to the AVR, same as Atmos.There's been some interest in this AVR elsewhere on QQ because of its support for MPEG-H 3D/Sony 360RA--although as far as I know, there's still no way to actually send a 360RA file to an AVR, unless you have Fraunhofer's MPEG-H Authoring & Playback Suite, which includes a software audio player.
I've tried with my AVC 3800, but I get only stereo.I’d assumed you could simply bitstream 360RA from Tidal to the AVR, same as Atmos.
Maybe? I guess I should do a little more research. Somehow I thought 360RA was still limited to mobile phones, but maybe that was an erroneous inference based on the effective absence of compatible AVRs before now.I’d assumed you could simply bitstream 360RA from Tidal to the AVR, same as Atmos.
That is correct. They are less expensive! $1200 at accessories4lessMy Marantz SR7013 at a closeout price of $1600 was a better deal. Same power output, Atmos, Auro 3D, etc. But only 4k switching on the 7013 vs 8k on the 7015, and perhaps one or two less bells and whistles.
I'm very happy with my SR7013. However, I don't think any SR7013 units remain for sale at that low price.
It’s Marantz Factory Refurbished. For $1200, I would not let that stop me if I wanted an AVR. Also, it has 7.1 analog inputs, albeit the only thing that functions on this input is the volume control…No Audyssey, no Auro3D, no tone controls.That is correct.

also - I am guessing that the OP's issue is a stray speaker strand making contact with another.
I have bought from them before without issues. Are there any AVRs that Audyssey, etc. accepts analog inputs?It’s Marantz Factory Refurbished.

In line with boondocks' comment, I've got a couple of these on my receiver and they keep it WAY cooler: Quiet USB fansI have for a long time used a computer 240mm fan with the rubber mounts sucking the hot air off my AVR.
I got mine for $3K less than NZ retail too. Great price. Not sure I'd have sprung for it at full price but very glad I got it as it allowed me to experience Audyssey for the first time which works wonders in my room.My Marantz SR7013 at a closeout price of $1600 was a better deal.
