Never had that issue with that type of rip before, how odd
I had an interesting problem on a plane over Thanksgiving weekend. I have a new file that is 192/24 that is one long double album (bin master rip of Physical Graffiti 1:20). As soon as the player's screen went to sleep, the file started breaking up. If I touched the power button to wake up the screen it played fine. Sort of a bummer. Was fine on shorter tracks and lower resolutions.
They are more geared towards money than their customers IMO. At least when compared to Fiio that is. Wouldn't hold my breath lol.
Anyone try this cable (Silver Dragon Toslink) ?

Is there any expert programmer out there that knows how to make a new version of the AK120 firmware so it can play native DSD on the RWAK120S/B?
It is a hardware limitation, not a software limitation.
The S-mod chips used (Wolfsons flagship) are not hardware limited to that. It is software limited in this case. The original chips that came with the stock AK120 is limited though as it doesn't have that feature to do native DSD playback implemented into the chip.
Putting the firmware aside (as I do agree the firmware has to support DSD) but I'm not certain about not needing supporting DSD h/w around the DSD DAC.
I could be wrong but I thought it's not as simple as plonking in a DSD capable DAC into a product that's designed for PCM even thought the DACs may be pin-out compatible. Wouldn't there be surrounding h/w component to enable/support DSD like the 64fs clock + various gates to enable/disable between modes?
If I look at the WM8741 datasheet, just looking at a few pins 1-4 they double up for PCM/DSD purposes but in different order. For example, picking up Pin 1 only, if it's PCM then Pin 1 is the L/R clock. But if DSD then Pin 1 is for DSD L input. I'd expect some kinda h/w gate external which would decide/switch for Pin 1's use for PCM or DSD.
Or are you saying that the AK120 already has the supporting DSD capable architecture around DAC?
