Perfect, but should I set the volume to 100 on this case ?

Set it to line-out mode.

Anyone else hearing tonal differences between the outputs? To me SE sounds warmer than BAL. Not a big deal because technical performance is the same (which is surprisingly uncommon on the market), but I just want to confirm I'm not mental

Not surprising. My UP4 sounds different when switching between low gain, high gain, and boost mode from the same port, using the same IEM (P8).

Headphones in my collection that this DAP sounds amazing with:
1. Klipsch HP3

Consider trying them out if you love this DAP

Is there an advanced manual for M1S available? Or only for M0?

 

[carpman]

Agree - an advanced manual for M1s would be very helpful.

The gain issue on Line Out is a little more complex than simply more is better. When feeding an amp with a non-logarithmic volume control you can end up in the very early stages of the volume control range and my understanding is that some amps have less accurate channel balancing until the volume control is pushed higher.

Would be good to have more in depth information on the DAC, USB Audio and Line Out stuff.

Also, I notice when charging the M1S, it turns on as though expecting data from a PC, then I have to power off for it to show the charging screen. I agree with other posters that having an approximate display of how much the battery is charged would be useful. It doesn't have to be accurate down to the % point. But for me, so far the battery status is the one main weakness of the M1s' UI.

If you have amplifier that has issue with channel balance, just run M1s at like 50% volume out and it should be better.

What details would you be interested in in regards to DAC, USB Audio out and Line out?

We do not plan any adjustments to charging screen or battery level.

Line Out is fixed at 100% - at least that what I thought.

Oh, and while I'm here. If I want to create a playlist and import it.

The structure on exported playlists (m3u) =

A:\Folder\track.flac

So I create the playlists I want on my PC and place it in the M1S playlist export folder.

The M1S imports the playlists no problem and can read the tracks and play them. But it fails to properly scan / read all the meta data (even though those files appear in the library and all their data is present., Any idea why the M1s is not properly picking up the meta data on imported playlists when it can find the tracks from its library (where the data is all present) ?

If your amplifier has any issue with voltage in Line-out mode, just turn off the line-out mode and set volume at lower level.

Our system is unable to read tags correctly when running from imported playlists. Issue on software team side.

 

[carpman]

Thanks for the update on imported playlists and meta-data - hopefully that can get fixed for a future firmware update.

As for the amplifier "issue" -- my amp is fine - but something a manual might address are such issues as Gain vs Volume (there's plenty on the internet about channel accuracy at very low volumes on amplifiers).

Re. Low Gain (DAP) + Higher Volume (Amplifier) vs High Gain (DAP) + Low Volume (Amplifier) :
https://audiosciencereview.com/foru...o-use-low-gain-or-high-gain.22156/post-735175

The general (consensus) advice (from researching this) is that if you're using Line Out and don't need the extra gain, keep gain on Low and let the amp do more of the heavy lifting via its volume control. That's what I've done (after researching this) -- but again this kind of advice might find its way into a manual. As well as a better description of what USB Audio does / is for and how it bypasses the internal DAC. Also you could state that the L/O bypasses channel balancing. This is the kind of thing a more technical "advanced" manual would go into.

I bought the player mainly as a mini music player for a small room. So M1s > Amplifier (Class D) > Passive Speakers --- it's doing a great job and in the main I'm very happy with it. I realise that most people will use this as a DAP > Headphones. But having a proper L/O option is really useful and is one of the main reasons I purchased the M1s.

I just feel there are a few minor issues that if addressed would nudge the M1s closer to being perfect.

Cheers,
C.

Just in case anyone is interested in the Vol vs Gain and Amplifier Volumes / Channel imbalances at low volumes (this thread on ASR covers it):

At low volumes, the signal input voltage is dropped over virtually the entire length of the resistance tracks. Making two tracks (L/R) identical, especially when they are attempting to create a semi-logarithmic relationship in the material (resistance vs rotation) is difficult. It's amazing they work as well as they do.

Source: https://www.audiosciencereview.com/...-imbalances-at-low-volumes.14276/#post-438004

The reason for the imbalance at low volumes on dual logarithmic audio pots (volume controls) is that at low volume settings, one degree of shaft rotation causes very little change in resistance. At higher volume settings, that same one degree of shaft rotation causes a much larger change in resistance. It is difficult to accurately screen on the resistor ink uniformly through the entire range of rotation, and tiny errors on the low end of the pot cause much larger volume variation than the same amount of error would at a higher resistance portion of the track would, because the same error represents a larger percent change at the low end than it would at a higher setting of the shaft.

Source: https://www.audiosciencereview.com/...-imbalances-at-low-volumes.14276/#post-438711

Thus, if the player chain is : DAP > Amplifier > Passive Speakers, sometimes it's better to do L/O with Low Gain (as it states in the manual ... oh wait, it doesn't).

Buttons on the front panel? I wonder how easy will they be to use, especially with DAP inside the pocket.
I would prefer a bigger screen with buttons on the side.

Just got it.
Buttons on the front is perfect. Pause, forward to next, or back to beginning of song or earlier.
Great for when I have turned off the screen all else, yet the buttons still respond. No need to try to see which button i am touching.

As for the interface, my fingers quickly got used to sliding as needed.

And sound is great.

Ah, another Porta Pro lover! I run with these dorky things! But, they are the best throw away headphones on the market PERIOD. I have the M0. I was thinking of getting the M0 Pro, but now the M1S is calling my name. I would like the bigger (screen) size, but is it too big.?. I'll have to glue a clip to the back of it, though - but big deal!

On its own, the M1S is thick yet small. It's certainly light enough for a clip-on type of setup. However, I found it too bulky for a DAP-->DAC setup with my Chord Mojo 2.

@Shanling any updates on TIDAL support ?
What about the playback of DSD + .cue files, it's already fixed ? (the player can recognize the .cue file and split the DSD file on to tracks ?)
