Is it powerful like the M3 or like the M2 ?   By the way can it drive fullsize headphone .?

Tx for this explanation ; what a odd operation 

anyone could confirm or not that the equalizer is not usable ?

anyone have activate the equalizer ?   With mine it doesnt work 

i dont understand what you mean    I was afraid to put in it with much force but now it is done and it works with my external DAC and AMP

sorry wrong information : it works with optical in

 it works with optical in For the gapless i dont think it works with the new firmware ; but this is not important for me 

The sound is really fair with a lot of details and a really interesting soundstage   The UI is Cowon P1 like    That for the good one    On the other side : equalizers are out of order - when you turn of the Opus is not able to start with the rules you have choose before shutting down- no...

My Shanlng M2 review is here    http://www.tellementnomade.org/preview-shanling-m2-en-toute-transparence/   If you can read the french language that's ok, if you can't Google Translation will be your friend 

I totally agree with that  and also surely interested by your new project M2. I hope so you will not stop the development of the M3 firmware.

   

someone to know what is "Playing Surfaces" in the sound menu of the M3 ?

My review of this amazing DAP is here (i apologize but it 's in french)   http://www.tellementnomade.org/preview-shanling-m3/

i will appreciate the possibility to change the volume   i will like the possibility to have some other option on upsampling (like the AP 100)

and if i use coaxial or spdif at the same time i charge the idsd i hope it will works 

Thanks for this answer

is it possible to charge it and use it with an ordinary AC/DC wall power ?

i just want to know if it is possible to use the HP-A4 with AC/DC wall power  (like my smartphone wall power with the AP-A4 usb Cable)  and connect it to my source with optical in or if it is only possible to use it connect to the usb port of a computer 

  Great that's ok now   

With the new firmware i am not able to add songs to favorites    is there a solution for that ?

you can change bass and treble 

could you give the link ?

I use a the same cable used with the Hiddizs AP100 or Fiio X5 connected to the "coaxial in" of my DAC   what kind of cable will works ?

Connecting by the line out is ok but i cannot use the optical output as i do with my AP100   is there a manipulation to do for that ?
