How does M0 sound like connecting with Hugo2 DAC?

 

[oldschool]

My unit behaves erratically sometimes - spontaneous decreases of volume to zero or very low level, jumps to the beginning/middle/end of tracks, skipping or rewind to the start of tracks, spontaneous additions of tracks to favourites (even if I tried to do this myself it can be challenging pressing the heart icon due to the tiny screen), etc.

Wonder what could be causing this, it can be quite annoying at times. My double-tap of the volume wheel is set to "pause", I don't think I am touching any controls when the above issues happen, and the screen is also turned off. Could it be because of the integrated remote control on the earphones I use, or interference with my iPhone (although bluetooth is off)? Or could interface buttons be somehow pressed on the screen when it is turned off?

Just 30 min ago, while sitting in my pocket, the player skipped a track, added the next one as a Favourite and changed the play mode from List All to Shuffle. I went back to the original track and this time it played fine, so the problem is not in the file. .. What???

... added the next one as a Favourite and changed the play mode from List All to Shuffle. ...

Aha! I thought I was seeing things. I have had my play mode changed to shuffle several times too but thought it was me being clumsy and perhaps touching something without noticing.

My m0 arrived this morning - it's a nice looking unit and easy to use!
I have noticed however that when using it as a usb transport into my Chord Mojo is doesn't sound quite as good as when i use UAPP in bit perfect mode from my android phone. There is a definite lack of spaciousness/clarity noticeable, particularly on hires albums when using the m0. It is really obvious when listening to the intro of Halo on my 48-24 copy of Depeche Mode - Violator.

Why would this be? It Is there a bit perfect mode i am missing causing the m0 to do some additional processing?

EDIT: I've just noticed that the EQ settings still take effect when using the usb output. This would imply that the data is being processed somehow and that it is not a bitperfect output...

According to our engineers, M0's output is bitperfect and there is no processing.

Of course when you enable EQ, it's something else and of course it changes sound, as would any software on your phone or computer.

Please contact your seller and ask him for replacement unit. This might be the "ghosting" issue we had on few early units.

hi @Shanling , I reset my speaker and removed all the previous pairings but still no luck. My m0 doesn't show which codec it uses when connected (apart from the traditional bluetooth icon).

Can you try with any other BT device?

I have noticed it once in awhile and assumed I hit the shuffle mode icon inadvertently while swiping. I really think Shanling needs to swap and put the progress bar and track count on the main playback screen and put the shuffle mode, favorites and Playback options icons on the secondary screen. That to me is more logical and more in line with what I am use to from my Sony A17. This should greatly reduce the inadvertent hits on the icons currently on the main playback screen.

Hi. Thanks for replying.
Please could you double check this statement, and maybe get your engineers to compare the output with android UAPP.
I really don't think the output is bit perfect as it sounds noticeably worse than when using UAPP in bit perfect mode. It's also worth noting that UAPP sounds slightly worse when not in bit perfect mode and a DAC connected to an Android phone sounds worse still if you use a different media player other than UAPP entirely.

In bit perfect mode UAPP bypasses the EQ entirely. This is similar to the 'Source Direct' or 'Bypass' switch you might find on an amplifier. These switches result in a sound quality improvement because the EQ circuitry is removed from the signal path.
When using the m0 the EQ settings are still active, implying that the data is going through EQ software. - whether or not you set it to OFF or not does not change this.

This is what the author of UAPP said about bit perfect mode:

'Without the bit-perfect option enabled, all audio that is read from the file is converted to 32-bit floating point and then converted to the appropriate 16/24/32 bit integer format when sending to the DAC (after optional processing that you chose like EQ, balance,upsampling). This leads to an error for about 20 or so out of 16.7 million values that are 1 bit 'off'.'

It would great if you could get the best sound quality possible out of the m0 as I'm sure many potential owners would be connecting it to external DACs.

Thanks.

I only have my Apple Airpods, I tried with them and the m0 showed AAC on the top bar. That's so weird. So, do you think this is something Sony should be aware of? Are there any people using Sony's bluetooth speakers with LDAC? Can you guys see the LDAC logo on the top bar when you connected? Also what is the difference between LDAC-Connect(Auto) and LDAC-HQ? I want to get the best audio quality possible!

I have two Sony LDAC speakers and no I don't see the LDAC logo on the M0 screen. But when comparing sound quality via LDAC with my Sony A17 I can't hear a difference. As for auto-connect this is the lowest quality LDAC setting and optimizes the connection over sound quality. As for LDAC-HQ it has the highest transfer quality but the connection is the least stable and frankly overkill. I use LDAC standard which is 600 Kbps transfer speed vs 990 for HQ (906 actually is the highest I can get). I can't hear a difference between the two even streaming to my Sony receiver and Standard gives a more stable connection and better range.

When using my A17 via LDAC to my Sony receiver I can control the A17 with my receiver's remote control. I can't get this feature to work with the M0. So who knows maybe the licensed version of LDAC Sony offers to third party vendors is slightly different than what they use in house for their own products. Just speculation but maybe Sony doesn't share the whole LDAC secret sauce with other manufacturers just a stripped down version.

Im using wh-1000xm2 and it always shows LDAC at the top right corner when paired. Here's the speed of most bt codecs LDAC HQ - 990kbps. LDAC normal - 660kbps AptX HD - 576kbps AptX - 352kbps. LDAC Connection - 330kbps.

Can you charge M0 while also using it as Bluetooth dac?

No, charging only in usb mode (already wrote in this thread).

 

[Czoken]

Can't that be fixed with software update? I mean do i ask for much with this simple thing lol

Even full price it’s a great deal, I’ve been using it as my ‘main’ serious listening dap even though I have access to more expensive daps. For instance I paid 700 dollars for my ak70 but I prefer the sound sig of M0.
