You know it doesn’t matter what any of us say or show, we’re witnessing history repeating it’s self.
Most of us are just watching and don’t really wanna chime in cause we know the end result.

be that as it may, the point is that i can clearly hear the difference in your video even through the rather crappy pc speakers. and that despite the youtube audio quality. that’s what matters in the end. the simple fact that this thread has been created proves that others hear it, too.
i’m also not as pessimistic as Wyley1. although it has taken them years, denon did improve the sound twice before so i didn’t write them off yet.
In real life, on a real PA, with real people on the dance floor, that person talking to his friends next to you has more influence on sound reproductivity than the Denon player.
Plus, most PA setup will add a layer of EQ through a processor which will reduce the 16k+ range because in those frequency in the 100db range are really harsh and not pleasing to hear anyway.

Agree but when I want to use the SC6000 with high end monitor (genelec neumann focal ATC &) and acoustics treatment it’s frustrating to not have the best sound quality with a 1500 euros players.
Today you find some soundcard and dac with real high end specs and sound really transparent for 100 euros
For me this high end roll off not really fixed is not acceptable for a reputable brand like Denon DJ

doesn’t matter, scroll up to see the 128kbps mp3 test.
Rather than make people dig through other linked posts, just post the video here.
linked posts? video? 
none of that, just another post of this very thread.
I could not locate a 128kbps mp3 test in this thread.
that’s the one i meant. very simple and very effective:
So I went ahead and did that comparison real quick. The top is the sound from the digital out on the SC5000. The bottom is the source audio rendered to 128kbps MP3. As you can see, 128kbps is a direct cut at 16kHz while the SC5000 is a gentle roll off (0db to -3.5db) starting just below 16kHz.

maybe it’s the track. others as well as myself got different results as you can see in the linked threads.
also when you try to compensate the roll off with a high shelf, you gotta set that shelf to 12khz to match the original.
anyway it’s really tiresome to fight the seemingly never ending number of people who try to negate this for whatever strange reason. those who don’t hear it or don’t care about it, great, you’re lucky. i simply don’t know what else to say. it has been proven so many times by different people and is clearly audible. if that’s still not enough i can’t help it.
in most cases something like this is a no-brainer. it’s not as it should be and has to be fixed. no questions there at all. that simple.

I’ll have a chance to test the 3000 this coming weekend. I’ll post those results so we can compare.

oh yes please do. that would be very interesting. and please use tracks from different genres which cover the full range.
I agree this getting a bit tiresome & I started the dam thing, haha. I say better luck to you if you can’t hear the difference, you have nothing worry about, but I am going to go one more time here, so I can work out what I am going to do with this thing.
I know we have already discussed this & we have had some opinions which is great, I would like to invite anyone else to share & let me know if they have experienced an audible difference between using digital & analog outputs on the SC6000 & which they found to be better?
I know a few of you have said it has nothing to do with this & it is the internal sound processing or sampling done in the Engine OS that is messing with the audio signal before it is sent out & I think you are probably correct, but I need to consider all options & decide if I should buy an external DAC that receives digital output & then send that to my Xone 96 to see if that makes any difference, before I decide whether to keep this thing or not.
I love the Xone 96 & know it is an Analog mixer, but seriously wish it had catered for receiving digital signal as well & digital inputs, its kills the idea of bypassing a media players DAC.
At the moment, what I am experiencing is a lack of crispness in the hi frequency range on the Denon as opposed to using the Xone 96 through USB with Traktor software, I play quite a few different genres, Deep House, Progressive House, Organic House/Downtempo & little liquid Drum n’ Bass.
A Drum n’ Bass track provides a good example, if I play the same track side by side, you can clearly hear the hi-hats skimming away on the Xone 96 with Traktor where as the Denon I really have to strain myself to hear them in the mix, they are barely audible, the Denon doesn’t have bad sound, but is is hard to except the downgrade.
Does anyone believe Denon will get this right at some stage via software update, if it isn’t a DAC issue?
Am looking forward to seeing the results of the 3000 though…
Good analyse mate and thank you for the comparaison with Fabfiler Q3
With the SC6000 I can make the same test with the analog output and see if we have a difference with the SC5000, I have Fabfiler Q3 too so I can post the result later

It’s good that you posted this. Do you think you can cut all sources to 16khz and then test the sound quality of all in order to settle this
From the pics that you posted also verifies this
total waste of money.
that’s correct because the desktop software “engine prime” has the same problems. so it’s device independent and therefore also makes no difference which outputs you use.
it doesn’t matter where it starts exactly. as long as it’s as audible as it is now it has to be fixed. that simple.
That’s the purpose of the test. You cited a 128mp3 at 16khz as your championed source so therefore one must cap everything to 16khz to hear, and you’re right the difference in this test will be audible 
You’ll notice that most of us agree with you. Actually most of us already proved that the sound needs to be improved but you’re arguing with them.
Feel free to carry on your campaign though.

I thought the sound quality was not as good as Traktor when I got my 6000 M decks but put it down to something going on with Traktor to make it sound better in the same way some blue tooth speakers with DSP make everything sound great. Harmon Kardon for example. I noticed it especially with the summing of two tracks. I think I have just gotten used to it now. Any improvements would be great though. Still love Traktor but also still love the 6000 M.

even better and see below …
that’s not exactly the impression i got so far, but if that’s the case, well, great. the more support these issues get the better
