it’s fine, i believe you.
oh you did the test with 1.6?
well that would be fantastic. not your troubles of course but your results 
Denon DJ product leaks happens all the time, we need a firmware leak 
Truth. 1.6 is probably the second most anticipated firmware update so far. :-p
With such inconsistent results and the most recent findings, which appear to have been carried out with utmost care and consideration, it seems much less of an issue than one or two people seem to perceive it to be. As someone else said above, I think that a negative wash of placebo effect had infected a couple of people.
I think the primes sound great and no punters have run up to me during or emailed me afterwards to query the sound.

As you get older you lose your Hearing Dynamic Range… especially High Frequencies.
There will hardly be anybody that can hear to 20khz

not at all. the differences are caused by doing the test with a not yet publicly released firmware. all previous tests were based on the regular versions.
in addition there might also be differences between the sc5000 and sc6000 although as far as i know they should be the same in that regard.
Perhaps you can post your results then and perhaps others should post theirs also.
I still don’t see a feature request posted about this. On the other hand one first needs to know what’s going on first place to make a proper one.
all done months ago. just check my “crippled highs” thread and the others i linked above.
I did check them and I took part in them also.
You really don’t know why you get the illusion of better highs with 128mp3.
Oh well

illusion? i did an a/b comparison and it was clear.
He replied with this since 128kbps mp3 applies a brickwall/96db per octave shelf at 16kHz. It’s part of how the codec works prior to applying compression. So, to say a 128kbps MP3 has better highs is a good laugh, as they are not there to begin with.

i know and that’s actually my point because:
on the contrary, the good laugh is that the mp3 did sound better as far as the highs are concerned. which also confirms that engine os starts degrading before 16khz. in doubt try it yourself.
all of that is old news because i pointed that out in the crippled highs thread months ago.
If there are two same threads about the same thing, by the same author, can’t they be merged? They should be. I did read the older story but from the title alone and then by content it’s just coming across as desperate scaremongering. It’s better to have all the repeated commentary in one story.
Tempting, but “crippled highs” should have been merged with “high-end roll off” as well.
I think I’ll pass…

You’re right. The placebo effect here is one person trying to convince thousands.
Reading the posts from the majority, not from the one, it’s clear that the already improved roll off at top frequencies isn’t there accidentally. It seems it’s deliberately there because extreme highs don’t sound good through the excellent pitch/key lock for mixing.
Roll off isn’t a bad thing - if it was, there’d be thousands of owners of a certain yellow-coned bedroom speakers who’d be on their own crusade as their roll off starts at 14khz, not the dizzy highs of 16khz that the SC Primes offer.
Or will one lad attempt to start the Rokkit Riots ?

I can’t recall if I’ve ever commented on one of these “OMG the world is ending because there’s a roll off” threads, but here goes my two pence worth:
It’s an imperfect world. Our ears don’t have a ruler flat frequency response (especially adults that have been exposed to PA systems regularly). The rooms we listen in don’t have a ruler frequency response. Speakers certainly don’t have a ruler flat frequency response. Same for amps, same for mixers - and so on.
There’s not a whole lot of content that high up on a typical track anyway. Most of the energy is at the other end.
So, we are adults (presumably) and have lost HF hearing. There isn’t a whole lot of content that high up. The equipment we listen on is imperfect. The acoustics of the environment we listen in is imperfect.
Particularly considering these units are designed for DJs, who will typically use them in an entertainment venue, played through PA speakers, that use compression drivers, which have a reputation for sounding harsh and metallic - IMO it’s a distinct advantage to have a HF rolloff.
I’m no spring chicken, and I know my HF hearing has gone. Despite this, I can still hear music. It doesn’t sound muffled. I can DJ. I can mix. Nothing is muddy or confused.
I use my Denon kit to stream online. The audio bit rate for streaming is set to 128. Does anyone complain that it’s muffled, or missing highs? Nope. Not a single listener.

That there is a whole new thread on its own! Hearing so many different DJs online now, how they use the mic and what it sounds like, it’s quite surprising how some (inc very famous DJs) don’t seem to know or care.
And it is a good laugh.
Say I have a bongo with the best skin on it and I decided to change the skin with a slightly thinner skin. What would one expect to happen to the sound?
To make a 128 mp3 some of the underlying material has to be removed. It is this removal of the underlying material from the compressing that reduces resolution.
Our friend is confusing the effect of better sounding highs with thinned out sounds becoming more pronounced (not better sounding) at the capped frequency, and using it as a winning lottery ticket😆

After DJing for 26yrs, regularly on loud PA Systems, I know my HF hearing has degraded.
I did a sweep test…the best I got to was about 13khz
And as you quite rightly mention, nobody can hear to 20khz and above
