Just purchased a second-hand R5S from a fellow Head-Fier a few weeks ago. Really loving this device. I owned the R3 Pro, but found the sound signature not to my taste. I definitely prefer the R5S over it.

I was perusing this thread for any info on screen protectors, but don't see much on here. I'm assuming there still isn't any viable tempered glass protector for a different device that works on these. Is there any good place to get factory replacements? I don't see them on Hiby's official site. I'm really just seeing a few aftermarket options on Amazon.


I was also curious if I missed a setting to swap the next/previous buttons. I remember that being a setting with one of my older DAPs. Not sure if that is an option on these devices or not.

The screen protectors included and pre-installed and very thin. Mine were so difficult to see I thought they weren't on there. I have a couple extras if you need one. Look at the edge under a bright light and see if they're already there.

I have a technical question for you if you don't mind. Is there a good reason why you can't find a DAP with system-wide PEQ (preferably 10 band). I generally like to add a bit of EQ for many of my IEM/headphones and want it on all of the time for every app/source (and preserve bitperfect/MQA). MSEB seems to do this, but I would rather have more control (and be able to load presets like AutoEQ). The convolution plugin sort of did this but only at a single sample rate (and it no longer works on R5 - immediate crash of the settings app).

It sounds simple, but maybe it's not. I would think there are quite a few people that would find this useful.

I understand what you desire but once PEQ is introduced bit-perfect is no longer possible. Can't have both.

Hi there,

I can't answer for other manufacturers so I'll just try to solve the problem with this one...

There appears to have been a regression in the code to the convolver in recent updates. Here's what definitely works for me:
1. a 32-bit integer file (not floating point)
2. that is 4 channels (not 1 or 2)
3. that contains identical copies of the impulse on channels 1 and 4 (no signal on channels 2 or 3, for regular EQ. Those are used for crossfeed / BRIR simulation)
4. and is silent in the first 100 samples or so.

If it still doesn't work, try sending me the wave file you have for me to edit. If the app is crashing directly, try removing the wave file you had it pointed to, or failing that a factory reset.

I am trying to get the team to fix the convolver itself but until they come back from Chinese New Year's and actually do this (across the range, too), I'd have to advise on how to work around it like this for now...

Best regards,
Joe

I understand what you desire but once PEQ is introduced bit-perfect is no longer possible. Can't have both.

I suppose that depends on how strict you want to be with the definition of bit-perfect. Obviously the desire is to have maximum quality throughout the playback chain (sample rate, MQA decoding, etc) but to be able to apply correction to address transducer specific dips and peaks. Clearly, if this is done in the digital domain, the bits will no longer match the source with respect to gain/frequency. I guess I want the best of both worlds...

Roon, for example, will let you apply DSP (PEQ, etc) and yet still preserve high-resolution and MQA encoding. I would just like to see this ability in a DAP for portable use.

Thanks Joe, you have already fixed a couple of convolver files for me back when the clicking sounds were an issue. But with the R5, I can no longer get any files to work without crashing the settings app. I suppose I could try a factory reset. It would, of course, be nice to see the convolver fixed so I don't have to ask you for help with every file.

Asking my main question again - is there any technical reason that Hiby DAPs can't add global 10 band PEQ similar to MSEB? If it can be done, consider this a feature suggestion...

Can you point me to where we last corresponded about the file fixing? That may have been before the recent regression so there's a chance we can still fix it for the current version.

No, I don't think there's a technical reason why it can't be done. Although, we were hoping to make a really good graphic interface for a multiband parametric equalizer. We ran into limits on the programming team, I tried to think up something that they could implement more easily while offering innovations / advances to the end user, and the MageSound Eight-Ball was born

Here is one you fixed for me a while back:

That was way before the recent regression. I don't know what they did to the plugin but it now only accepts only one format as far as I know. Like this:

Let me know if this still doesn't work.

Joe, any news on the R5 shutting off when one presses play?

as a car's line in is as far from an esoteric low-Z load as you can get, I believe there's nothing for it but for you to take yours in for repair

K. It appears the are multiple cases of this type of failure. This is actually my 2nd unit. Apos Audio replaced the 1st after the battery swelled and popped the back plate off.

Sorry to hear that

This one worked fine, thank you. Now if we can get it fixed on the DAPs...

I have quite a few IEMs that I would take the time to setup but I'm sure you don't want to do these fixes as a second job.

I do have a question: How technically significant is the sample rate matching when using convolution for EQ? AutoEQ has both 44.1 and 48 kHz filters (and apparently you can generate other rates with the tool - with some effort). Obviously if I'm listening to mixed rate playlists, I don't want to change the filter manually for every track.

Edit: It skips if the sample rate doesn't match, so never mind... not an option. I guess I'm back to wanting system-wide PEQ.

You mean if you uncheck "other sample rate bypass"?

Yes, correct. I thought maybe it would work like Roon where the convolution file is resampled to match the playback rate. Maybe that's too much processing for Android.
