Hiby R6 Pro II (2023 Edition) - Launch, Hype, Thoughts & More

[Etx1]

Because it’s a function offered by the DAC chip manufacturer and people buying the device want access to it.

Distinguishable or not should be up to the buyer to determine. I was not aware that it was supposedly fixed, hence I have not put in the time to test it. Now that I see it was supposedly fixed, I will give it a proper test and see for myself, as I should, whether or not I can or cannot distinguish between them.

But yes, technically, the differences would only be evident at extremely high frequencies, so A) the listener needs to still have sufficient ultra-high frequency hearing sensitivity as well as ability to interpret the audio information they are hearing and B) the equipment (IEM or cans) being used to reproduce the signal also needs to be able to even reach those frequencies accurately to translate any difference that there may even be.

That is me out of the equation for sure if one needs " ultra-high frequency hearing sensitivity "

That makes 2 of "us".

At the age of 42, my high frequency sensitivity isn’t what it was during my younger years, but in reality this has worked out in my favor, as when I was young, I found 90% of sound reproduction equipment to be too bright, both lower end and even some ultra-high-end gear (I used to attend CES with a press pass in my 20s). Nowadays, I find that to be the case primarily with some lower-end gear and only the rare occasional higher-end gear, maybe 25-35% of what I get to listen to, so either my high frequency hearing has dropped quite a bit and/or the overall quality of speakers, earphones, and headphones as dramatically improved—most likely a combination of both.

Regardless, to know for sure, I will try to get some listening tests in soon for the different filter settings, hopefully tonight, and preferably with some particularly bright sounding recordings.

Thinking All-Star Percussion Ensemble performing Carmen Fantasy would be a good start! The Glass Hall by Andreas Vollenweider should be a great test as well.

Hi thanks for the reply:

1. I have Artist, Album, Title. For example I have a Barbara Streisand album called Partners and in Artists & Albums each track is shown as a seperate album because there is a different artist collaborating with BS.
2. Yes there is track 1 showing twice and then track 2 showing twice etc etc.

Thanks

Do you mind saving a small subset of your library exhibiting these problems and sharing them with us via a dropbox link I'll send you?

Side note about @Nick24JJ referencing the 5K and BTR7: they both use ES9219C DAC/Amps. The datasheet says that the digital filter and system mute are set through the same register. Speculating a little, it is possible that, on these particular chips, you can’t change the filter settings without causing a (short) system mute. That wouldn’t be a feature then but more an idiosyncrasy…

Well to be fair, am testing it now and honestly hear no difference between settings, even on bright, sparkly tracks, with my Thieaudio Hype 4 IEMs. So you’re essentially right in that this feature is fairly pointless.

Aren’t we talking about audio here?
No player has momentary sound pauses when you change volume… Why changing the filters should be any different?
Either you can hear a difference and don’t need an additional indicator, or you can’t hear any difference… then why do you care?

Breathe. Fanboyism can cause asphyxiation...

Ok I've had it. Why don't you just sell your unit and move on?

That will be the official advice from me.

And I will NOT be editing this post.

These are the waveforms I captured from my R6proII first on firmware 1.30, then on 1.40, going through the list of AA filter settings from top to bottom, from left to right, while playing a Dirac impulse on loop.

As described in the original bug description, because I had gone through the list more than once by the time I was recording, on FW1.30 it was stuck on the last setting, same as the last setting on FW1.40. By the same token you can see that on FW1.40 you are getting all the different filter shapes as requested.

I tried to capture myself doing this on video, but my video skills fail me, as evidenced by the fact that I have no youtube, etc. presence to this day.

Thanks, Joe! Now there can definitely be no doubt!

Can someone test and see if a DSD track is played and see if switching between PCM, DOP or Native you can notice a difference in sound ? Not tried it for a while however there was a huge difference a while back on my player and now they all sound the same, not sure but I think this has happened since the last update unless I have done something on my settings somewhere.

should be because you turned off your plugins and sound effects. As said before, the sound difference you heard was the result of these being actionable on PCM but not DSD, and usually not an effect of the difference in decoding process per se.

@Etx1 precisely this—unfortunately none of the plugins, MSEB, global PEQ, will function with DSD-encoded music. It all only works with PCM.

This is why recently I have switched from getting DSD music and instead getting DXD. I also replaced what DSD files I have that I could with DXD version instead. All the software functions work with DXD, which is PCM.

Note also that these waveforms are captured when the player was playing a 48kHz test file (and recorded on the computer at 192kHz). Changing the filter will have no effect when the input sample rate is any higher than that. Not a bug, simply a fact of the matter that these filters are for changing what happens around the Nyquist frequency, and, the Nyquist frequency is already ultrasonic at 48kHz sample rate (24kHz) but absolutely, indisputably inaudible even to audible only to bats at 96kHz and beyond (48kHz and up).
