^ Oh look, they thought adding FLAC support may be useful to people this time round. 
 
Good thinking Aune! Not like their WAV only M1.

I would like to buy it, but must ditch some other stuff first...

The thing with the M1 is, that it has an Cortex M3 processor. It can only do WAV, not more not less. Also anything more than 16bit is a problem...

I love that, but 99% of other people wont consider it. To me its like a PCD player, with more CDs possible...

If I understand you correctly. There are two official DAC boards?


not officially,
chinese diyer sell his dac+amp board usibg the cs4398 chip, and i see on erji.net thet use wm8741 singe and double abd change the original opamp for lpf and headout.

Very interesting. I read somewhere on the internet, that the M2 is reaching his fifth edition of the prototype PCB, or something along the lines. I believe that it is not far away.

m

the battery accidentally stop to work so i replace with the same voltage but higher capacity, the size can't fit the space in aune m1 casing so i put the battery replacement out off the casing.
i replace the battey space with several capacitor to coupling the tda1387 pin 7 to ground since the dac need alot capacitance to get a good bass quantity,i took off all opamp related with lpf and amp, and the power supply for +-9v.
the pararel tda1387 x 4 can drive the 150ohm earbud to about more than equal to 50% volume.
