Hi guys,

I've been looking for a lot of Denon and Marantz AVRs from 800-3000 eur and even being in a different class they all use the same DAC AK4458 which I find astonishing!

Should there be any quality grading when we talk about DACs in a different product categories?

Hell, I even went to AK website to see of they make any other DAC but this one and they indeed do, many.

I know that DAC is one part od the story when it comes to music quality, but shouldn't we have better DAC in a Denon X8500H than in X3600H?

How does the more expensive model sound that much better, is it just bigger power or it's more to this?

I am not an electrical engineer, so I hope I don't say anything that will cause someone to rip me a new one.
From what I understand, there are many things besides the actual DAC chip which are responsible for sound quality. Engineers can add on 'features' when they implement the DAC like digital volume control, digital sound processing, upsampling, etc.. The power supply and analogue output stage also has an effect on sound quality.
Here's my feeble analogy:
If the DAC were the engine of a car, would all cars with that engine perform the same? Suspension, drive train, tires, etc. will all have a big impact on the cars performance. Just because two cars share the same engine doesn't mean they will perform the same.
Hope this helps!
The really smart guys will be chiming in soon to give you more accurate info.

I have avrs from several mfrs and none particularly new (Denon 4520 is the newest). The particular chip they employ I don't even know off the top of my head nor did that enter into my decision making. I certainly couldn't rank their ability to handle digital content as anything but generally equal to an extent (aside from general capabilities for codecs/number of channels). DAC chips have been a mature implementation for a while and just not something I worry about.

@PENG keeps track of dac implementation in several avrs, tho. @Beave used to be involved in the implementation of dacs in audio products, maybe he can add his .02 as well....

Audiosciencereview.com has some measurements on avrs and they particularly pay attention to dac performance....

For a good twenty or even thirty years now, even cheap DACs have had excellent performance. DAC chips have been a mature technology for a long time now. Sure, there are small measurable differences from one chip to another, but those differences are almost always below audible thresholds.

By using the same DAC chip in all products, they buy more of the same part, which gives them better high-volume pricing.

In most electronics parts, pricing is very dependent on the number of units purchased.

Example: Gonna buy 100 parts? They're $10 each. Gonna buy 10,000 parts? They're $5 each. Gonna buy 100,000 parts? They're $3 each.

Any time a company brags about the brand or model of DAC chip they use in their product, it's mostly marketing fluff.

The most audible differences, by far, in most receivers, is the room correction software (audyssey, mcacc, etc), followed by the power amp section - but only when pushed close to its limits. Much of the cost is from the power supply section - the transformer and power supply filtering caps. That's where they often cut corners. It generally only becomes a problem with inefficient speakers played at loud levels.

To answer your question, the higher priced models usually have far more features, the ability to power more speakers, a higher version of room correction (eq) software, and larger power supply sections leading to more power output for situations when it's needed.

Thanks guys, I guess I knew few things about the low cost of using the same old DAC model in a million units, power amp inside the unit and so on.

I know that many audiofiles are moaning about the sound quality of the avrs and lousy DACs they have, so one could think that someone like the Denon might give a higher end DACs in a high end avrs. Many guys buy separate DACs because of this and say there are huge differences in the sound quality on their system.

I started to pay attention to the DAC section since I don't have the money for a separates now, and I loooove music and I'm sick in the head about the sound quality. I watch movies too and like the surround sound and all, but if I buy an AVR and it sounds like poop I'd kill myself.

For a start I plan to go with a pair of Monitor Audio Silver 500, and later add other speakers. These are pretty efficient and any avr should be able to drive them over 100dB and make your ears bleed.

@beaver now when you mentioned the power, I remembered the Techno Dads clip where he compared the Denon 6300 avrs output (140w) on the speakers with the output when used external amp. He sad "there's no way in hell this avr outputs a 140w". So these ratings are not that accurate too.

Audiophiles make all sorts of claims about sound quality, but they rarely prove their claims with properly conducted listening tests or with measurements. The DACs in AVRs are usually audibly transparent (ie, they don't distort or alter the sound in any audible way). Audiophiles have very active audio imaginations based on the price tag they see on things or what they read in "reviews" (ie, industry propaganda). Buying a separate DAC is usually a waste of money but is satisfying to an audiophile's imagination (costs more = must sound better, which triggers psychological bias known as expectation bias, which tells their brain that it will and does sound better).

The vast majority of a system's sound quality is determined by the speakers and the room in which they are placed - and that includes their location in that room.

Audiophiles often spend endless amounts of money on things that don't matter - like DACs - while failing to focus on things that do matter - speakers and the room. Moving a pillow on your couch will have a bigger effect than changing a DAC, but it doesn't appeal to the psychological needs of many audiophiles. Moving the entire couch will definitely have a bigger impact on sound.

The Monitor Audio Silver 500s are pretty good. But you'd probably be better off buying the 300s, then using the savings to buy either the center channel or a good subwoofer or two. The only advantage of the 500s over the 300s is in the bass. A decent subwoofer (or, better yet, a pair of decent subwoofers) would beat the bass in the 500s easily.

As for the comparison, I haven't seen it, but I can guess it wasn't done properly.

That AVR will easily output 140W and more, depending on how many channels are driven at the same time. It only struggles to deliver its rated output when powering several speakers at once. And 140W is enough to drive the Monitor Audio speakers to their breaking point.

Take any Youtube video reviews with a grain of salt - there's a ton of misinformation in them, just as there is so much bad information from What Hi-Fi, The Absolute Sound, etc. They're industry shills, not educated reviewers with proper tech backgrounds.

I see what you're saying. Given the facts and circumstances I should be fine with a 105W avr (8 ohm 2 channel driven, as an example I took X3600H) for a stereo music. If I'd want to go for 5 channels it would output 80W per channel, and if I crank the full atmos setup than that power transformer wouldn't be enough to feed all the speakers to a great loudness without distortion (not to mention lack of bass.. and I know I would need external amp for a full atmos with this avr model).
I'd like your opinion on that YT video, just type A/V receiver vs amplifier what has more power, channel is technodad. He showed something that other reviewers didn't. Not pushing you, only if you're curious, of course.

That was in regards to a power. So I guess I shouldn't be worried about the 3$ DACs inside the avrs

Thanks again, you really cleared my doubts with your posts.

I always get some great information on this forum, you guys are amazing, very knowledgeable

PS maybe some of you are girls, no discrimination

Yes, but you might have been misinformed, by forum hearsay. The fact is, the Denon AVR-X8500H and the Marantz AV8805 do have a better DAC, the AK4490 two channel DACs that was the top AKM model a few years ago, about the time when the Denon AVR-X7400W and Marantz AV8802 were launched. Those two also used the AK4490.

Also yes, the more expensive Denon and Marantz model could sound better mainly because of the bigger power supply so you may expect them to sound better if used near the power output limit of the lower/cheaper models, otherwise you may need to be a certified golden ears to hear the difference.

The OP might be interested to know even the older Denon 4520 has a better DAC, one that is comparable to the AK4490 in the X8500H and AV8805, and significant better (numerically/on paper/specs) than the AK4458 in the other D+M models such as the X6500H and SR8012. Just case in point..not that it would make any audible difference in overall SQ and/or even on ASR's test bench.

I didn't realize they do have a better DACs, but they should for that amount of money.
You say two channel DAC, does that mean the AVR is using this DAC on fronts and even cheaper DACs other channels?
I know that a good DAC is more important for the fronts than other channels, I'm just making sure I learn how it works.
I think I read that Yamaha 3080 is using a higher end DAC on all processing channels.
Too bad you have to go over 2.5-3K to get a better DAC in an AVR. And they put the same in X3600 and X6500... I'd like to see a step up in other components, not just No of processing channels and power transformers.
There is a lot of specs misinformation on the internet though.

I think that's not unusual to have a multich dac for the mains being different from that for zones etc. Worrying about which specific chip still doesn't matter a lot, though....kinda like worrying about thd of .01 vs .02 %....just not an audible issue.

So much good and sensible information in this post, imo. I was going to reply with something similar, but not nearly as well worded or educated.

I strongly second going with the 300s and adding a good sub, preferably 2 before even considering a dac or upgrading amplification. The results will be more impactful and subjectively noticeable without having to convince yourself that you might hear an improvement.

I thought about 300s for a long time, but I'm not sure when I'll be able to for a sub(s), it might take a year or so. I'm little afraid I'll be disappointed with the bass of 300s. Specs say they go down to 32 Hz (which I'm not buying) and 500s down to 30Hz. I somehow think there's a greater difference in bass capability between these.
Edit: price difference between the two models is 280€

I guess a difference of 280€ won't be getting you a pair of subs. It'd be tough to find a good single sub for that actually, but it's a good start. I still think you'll have better bass (better, not just more and louder) with even a single well-placed sub than you would get if you step up to the 500s.

I'd say that you could probably get something pretty decent starting in 500-600€ range tho and you would have a 280€ head start buying the 300s. You could tough it out for a bit while you save the rest and end up further ahead in the long run.

Then start saving for a second sub! :p

I guess you convinced me

But there is a waf so a sub need to be the same..I was looking for a MA W12 sub but it's expeeensive.. I'd love to get some 14" but the one's I'm looking at (MA, Dali..) are just too expensive, I'm never going to get neither one apart from wanting a great sound I want a great looks too. I'm just full of flaws..
