Denon AVR or Anthem AVM70

I have heard a lot of YouTube reviews stating that AV processors have better components and channel separation. Hence was considering costlier AV processors. Any thoughts?
Just because someone talks on a youtube video doesn't necessarily mean much as to what they say.... Look at the measurements as has been suggested, it just doesn't bear out for most....

It's too bad no one ever implemented Audyssey's ability to manage four subs independently....that could have been interesting. For two subs Audyssey XT32/SubEQ works very well (and a lot easier than using a minidsp :) ).
I can ask AskAudyssey to find out what they would recommend. May be there is a trick that can be applied, with the App.

Thanks A lot for your feedback. Also wanted to know if there is any benefit in having a better DAC chipset. Denon uses AK4458VN in their AVRs and Anthem AVM70 uses AK4490. Does this have any impact on sound?
I highly doubt you can hear a difference between -107 dB and -112 dB THD+N, unless everything in your audio chain is top notch including your loudspeakers, room, placement and your room has close to "0" dB ambient noise that is practically impossible.

For example, if the loudest spl you listen to is 70 dB average, 90 dB peak, -107 dB THD+N would mean all the noise and harmonics would be at -17 dB below 0 dB, worst case scenario. 0 dB is what experts consider inaudible to most people.

If you listen to ref level, that is 85 dB average, 105 dB peak, say even 115 dB peak, then -107 dB THD+N means the harmonics and noise that don't belong to the original music signal would be at 8 dB, so while that would theoretically be audible, it is still unlikely because your room noise would likely be at least 10 dB over the audio band so in addition to masking by the music itself, it also gets masked by your room noise.

All these assume you have super hearing.

Still, given the choice I would pay extra for the AK4490, it shouldn't be much more, may be $20, if that, and that's why I despite integrated amps because for AVRs I can understand because of the lower profit margin on per unit basis, but for integrated amps, there is no excuse for the likes of Hegel, Anthem, Yamaha, Parasound, NAD etc., to put second tier DAC ICs in their amps.

Keep in mind the DAC IC is just one part in the audio chain there are also other ICs such as the preamp volume control, switches (also ICs in most cases), and at least 1 or more opamp buffers. Each has its own THD and noise, so you do want each part to have the highest possible spec as distortions and noise of the parts all add up.

The DAC IC is not always the bottleneck, in the past, more often than not, the volume control is, because most AVRs and AVPs (including Anthem, NAD etc.) used LSI chips (large scale integrated) that to perform multiple functions and their THD+N specs would typically be worst than the medium scale ones that specialize in fewer functions. D+M upgraded that chip by using multiple MSI ones so if you buy their products from say 2016, the volume control chip should no longer be the bottleneck. They also upgraded the DAC IC tot he AK4458, the specs of it sort of matches the volume IC. Unfortunately they use the same IC in the AVR-X8500H and AV8805 and I think that's the reason why the X8500H did not measure that much better than the X3600H, or even the X3500H (at lower output). On the M side, it gets worse, I suspect (other engineer hobbyists too, I think..)HDAM is the one responsible for the added THD+N, but that's just my educated guess.

Those gents in that video you watch would not have said what they if they have viewed the bench measurements, read the information in the service manuals and have the knowledge to understand what they read. I bet they did not do any of such things, but simply read the marketing material and listened to the dealer reps.

I think I could guess which one he viewed and that one was as I said, done by two gentlemen and it was a hilarious one, though I bet they were serious.

Gene's one didn't help much either if someone only view part of it and pay attention to the part they like to hear such as the theoretical benefits of the HDAMs, and "separates" in general. If you view the whole thing and listen to everything in detail then it would fine, expectedly as Gene is a good engineer in this field.

Hi,
I am currently running a 5.1(2 subs).2 home theatre setup in my living room. The Speakers are Monitor Audio Silver 6 front left and right, Monitor Audio Silver Center, Monitor Audio Bronze FX for side surrounds, two SVS Prime Elevation for Atmos and two SVS SB4000 subwoofers. The AVR is a Marantz SR5010 which operates as a processor. I am using Emotiva XPA5 to power all ear level speakers and Emotive Basx 8 powering two atmos channel. I wanted to change my AVR so I can add more channels and to improve the performance.
Need feedback on whether I should buy cheaper Denon AVC-X3700H / X4700H and use Pre outs or go for Anthem AVM70 which is double the price and has more channels. I would be immediately adding two more atmos speakers and by upgrading would be able to have two separate subwoofer channels. The long term objective is to have a dedicated home theatre room with more speakers and not having to change the processor frequently. Also would there be an improved performance with regards to audio by buying Anthem AV70? I have read interesting reviews about Anthem products. But Denon is a larger brand and I feel has better support. Please help with your valuable feedback.
Today is a strange time. New devices have not been tested yet, Denon / Marantz with HDMI 2.1 has no advantage because it does not work properly. In your place, I would decide between SR8015 and AVC8500 and I would lean more towards 8015 because it doesn't matter if preamp mode is turned on and it is cheaper. But if I already had some power amplifiers and I knew that in half a year I would have a dedicated room, I would risk the Anthem AVM70. It would be my decision and my money. No device is perfect and I would just risk it. It's your money.

That would be really cool if the avr could offload the processing power to the app....
