Tech Tuesday: Achieving Bit-Perfect Playback on Your WiiM Devices

[onlyoneme]

As far as AM is concerned, I don't think it does downsampling either. If limit of the playback device is 24/48, AM will play a 24/48 file .

That should be easy to verify. If you are right then both WHA and the DAC will show 48 kHz. If I am right then WHA will show the original sample rate.
In tidal we have the second scenario.

This means you get to experience your music exactly as the artist intended

The acoustics of your own room will immediately ruin this. But bit-perfect sounds of course desirable at first.

A properly used EQ is much more beneficial for the sound than bit-perfect.

Yes, both WHA and DAC indicate 48.

I've never used Tidal, but I recall that on Qobuz all tracks were played at 16/44.1.

"Bit perfect" has turned into one of the many hifi dogmas. Maybe it's the word "perfect" that made it so.
That said It's a nice option to have, turning all processing off. Let's hope the digital filter will not default to NOS.

you have to keep "control over the choice of digital filter"...

Hi Mr Ee,

Currently, enabling bit-perfect playback mode is a bit complex. Next month, we will add a simple option in the WiiM Home app to allow you to easily enable bit-perfect playback.

Saved configs/profiles could have accomplished this too and made smart presets more flexible. Just saying

Yes. The @WiiM Team must get a more generic approach to the design.

All these small features all over makes it difficult to use and maintain. Think big!

What are your thoughts about it?
Do you disable the options such as volume control,EQ to listen to the music without this?

Maybe with good recordings bitperfect listening? Not so good recordings choose EQ?
If there is too much clarity in a recording ( for instance if you prefer more bass) isn't it fatiguing to listen?
What are your thoughts about this?

For instance if I listen on my smartphone with the Shanling UP5 and my Moon drop Kato IEM i never did use EQ..
Haven't an EQ on the Shanling and never installed and app for EQ.
But sometimes I would think I want more bass..but a Kato has more bass then for instance another cheaper IEM from Moon drop.

So i would think using EQ could be important..or do you disagree?

How to Set Up Bit-Perfect Playback on WiiM Devices​

Setting up bit-perfect playback on your WiiM devices is a straightforward process. Our detailed guide will walk you through each step to ensure you achieve the best possible audio quality.

You can find the full step-by-step instructions here.

Hi,

In the guide is stated:

1. Make the following settings:

• Enable Fixed Volume Output.
• Keep Volume Limit to its default setting (100%).

And also disabling per source volume control and input pre-gain.

In what measure does volume control impact "audio quality" via non-bit-perfect condition?

I will never disable Auto-EQ since I've manage to get awesome results with it.

In comparing to EQ what is the relative impact of volume control on sound quality?

Does setting volume control limit set to other than 100% as the same impact as volume control?

Of course the answers may be relative one.

Thank you.

Probably no noticeable effect on audio quality but obviously not bit-perfect.

Thanks and it's what I assume (including ear listening).

I was just wondering if digital volume control would be to introsive in "audio quality".

Anyway I can not have bit perfect since EQ is of the most importance for me. My room has around a peak of +15dB around 49Hz which, if not compensated, mask my entire bass and is anoying.

I now have correction from 35-500Hz and have a pristine (detailed and deep - for my B&W 805S) bass and mid-bass.
