First time power amp buyer... now which receiver??

@KEW - I think it depends on if you are using ECO mode. I was running ECO mode as my 4500 and 4700 were running hot after a short session. ECO reduced heat but also cut amp power by 50%. I can hear the difference between using the Denon in ECO mode vs using the Monolith 7X external amp at moderate listening levels (70db+).

I purchased the AC Infinity AIRCOM T10 to fight the heat issue but I could hear it's fans even at the lowest setting so I returned it. I'm going to try the AC Infinity MULTIFAN S7 and see if it offers less noise.

Until Denon provides better cooling across its receiver line I see why an external amp might be a viable option for reducing heat. If you don't care about how hot the receiver gets then turn ECO OFF and use the internal amps. OR maybe you can find a fan setup that doesn't distract from the music/movie?
Finding quiet fans may depend on how low your noise floor is to begin with. I use a pair of fans with a speed controller from coolerguys on low speed that I don't hear in my living room setup; in my workshop I use one higher speed one that's noisier but out there it simply doesn't matter....fans are more due to the somewhat tight spaces the avrs are in...they don't run hot particularly in those locations...but with the fans they don't ever go beyond "cool". I don't have the Eco feature on either avr (older Denons). The newer one if I use all external amps, which I don't, I could turn off the amps in the avr, tho.

Is this possibly something akin to the DSP Delay in many subwoofers? A redundant approach to setting Distance/Delay where the subwoofer is "twice the distance" away?
Hard to believe normal delay management wouldn't suffice....especially if it only affects the LFE signal....

I decided to buy the Denon 4700 instead of the 4500. Figured that would be the newest technology and offer 125watts per channel. We will see how it turns out!

I don't know much you paid for the 4700. However, just based on retail pricing, why spend the extra 500 dollars for the Denon 4700 over 4500? For example, what kind of TV do you have, do you have an 8K TV to take advantage of that capability? Even if you had an 8K TV, where's the content to take advantage of it? I just understand spending extra for features you don't even need or use. I think by the time 8K might be practical Denon will introduce new receivers (ie 4900) with useless, superfluous features.

If you are talking the normal Delay/distance determined during the setup, this would not detect or correct for a delay inherent to the actual recording!

From Denon:
Bass Sync
For contents recorded in multi-channel such as Blu-ray discs, the recorded low frequency effects (LFE) may be out of synch and delayed. This function corrects such a delay of low frequency effects (LFE).

LOL before first cup of coffee....was more riffing off Ryan's post rather than remembering the stated use in the 4500 manual....

I’ve had a couple people say that but the majority of them say the paradigm 100s need more power than just the receiver.

I was able to buy my Denon 4700 for 10% off and free shipping. That took it down to $1529 total. If you want a deal you have to ask. After my refurb experience with Accessories for Less I would never buy a refurb again. I shipped my 4500 back to Denon authorized service 33 days ago and it's still not fixed. I called two weeks ago and they said they were out of parts. NOT going that route again.

You can find the Denon 4500 on sale for $1199 as they are trying to get rid of the old models. But, personally I would rather have the 4700 for $300 more.

I got it for $1400 while the 4500 was $1200. Figured $200 more was worth it in my book.

I am also in a situation where I am considering the 4500 vs 4700 (although I haven't completely settled on a Denon yet) and contemplating whether it is worth the additional $$ as well as whether there is enough of a difference to warrant going to the 4xxx series from the 3600 or 3700.

I don't anticipate using an external amp. As I only have a 5.1 system, I am however interested in seeing if the Atmos Height Virtualization is something I would like -- I have seen both positive reviews as well as some who believe it is just an unnecessary gimmick. In any event, that alone should probably not be the deciding factor.

I'm interested in hearing your experience with the receiver, the heat (which is the one thing really concerning me about Denon/Marantz) and where you wind up on the internal vs. external amp issue.

For sure man, I’ll try to remember to post my update once I get it in.


I ultimately was planning on the power amp but I liked the idea some said. Get the receiver and if I’m happy save myself $1,000. I honestly didn’t do much research on receivers. I’ve just heard Denon, marantz, Yamaha were all good. The Denon offers the most channels, watts, for the price.

To me the Auro-3D setting sounds better than any other mode besides stereo. If the 3700 had that feature I would have purchased it instead of the 4700. The 4700 also has more settings for Auro-3D than the 4500. If you're using the Height channels you'll want to checkout Auro-3D. It's awesome.

Yes. But the majority of all this Audio Video stuff is more want then need
Yes, but you still shouldn't blow money on nothing. Many of those consumer electronics companies are doing just fine. They don't need free money from us.

Actually a lot of audio companies, particularly the high end stuff, rely on such dollars :)

If my top priority was saving money I would simply buy a pair of headphones and never read this forum again. :D

And I was just spitballin... :p
However, I wouldn't put it past some wierd snafu in the machinery to c0ck up the LFE output compared to the standard bass management. I have a more difficult time believing that the production of the recording is to blame. That isn't a new process. But perhaps Denon saw something happening in their own gear as BM and LFE are processed in the AVR... that a different delay was happening between the two?

I'm not suggesting that you save money, just trying to discourage consumers from giving it away. Companies like Denon are international and profitable, they need monetary gifts and donations from consumers.
