I've asked Kingwa if he will use a VIA chipset for the new DI and he confirmed that he will indeed use a VIA chip ( most likely the same as used in the current USB32 implementation ). He also told me that the new DI will have a new firmware, much better power supply and better / shorter output...

2014v7 was just released. Perhaps it fixed the 32bit support.

They just released a new FW ( for DAC only ), FW2014v5. V5 improves DSD playback, so it should help only the ES91018 based DACs.

To me it seems that the sound is pretty much the same between v2 and v3. From what Kingwa said, the change between v2 and v3 should be DSD support

On SqueezeboxTouch + SA-2 via USB 24v192 works perfectly on 2014v2 and 2014v3.

The latest USB32 update ( 2014v3 ) added DSD support, so I think that just updating the FW should do it.

I had the DAC19DF ( the one without the DSP like yours ) and I've upgraded to the AudioGD SA-2 and I'm quite happy with the result. While I do consider the SA-2 a clear improvement, it's price / performance ratio is worse than the DAC19DF had.

Yoiu have 3 doc(s) in the rar archive. You should read them in the specified order ( they are named 1_Read me at first.doc, 2_Firmware update  guide.doc. 3_Driver2014 install guide.doc ). If you want to update the FW, 2_Firmware update  guide.doc explains how to do it.

FW #11 is for DIV3 as far as I know. The #9 and #9-3 are the latest ones ( except for 2014 ) for the Master 7 ( or any other DAC integrating the USB32 )

The #11, #10 and #10-3 are for DI-V3. For your NFB-11.32 you should use #9 ( SBT support ) or #9-3 ( SBT support & USB 3.0 improved stability )

I'm using a SA-2 ( internal USB32, FW #9-3 ) connected to my SBT and it playes 24/192 without problems ( I've used it via WiFi as well as via wired LAN ).

I also like the Hifimediy Sabre. Both my wife and I own one and we use it when listening to music at work. I think it has a great price / performance ratio.

All Squeezboxes have ARM CPUs, but as far as I know only the Squeezebox Touch has both an ARM CPU and Linux.

I just flashed FW #8 ( #7 version, tweaked for SBT + EDO ) and I can confirm that it's working in ASYNC mode with the SBT without any problems so far.   PS: I've also tested by switching back and forth between 16 / 44.1, 24 / 96 and 24 / 192 material and I didn't encounter any problems.
