Many reports here say "FW v1.61 NFB" is more stable. Therefore, I spend some time to repeat the test procedure I did for the other FW versions in the past:
(HDMI/IIS)-> AudioGD R7 (IIS input):

(BNC out)-> Hugo 2 (coax in):

(XLR/coax/toslink output)-> RME ADI-2 pro (XLR/coax/toslink input):

Summary for FW Version 1.61 NFB (GU16V1_61_NFB.rom) (https://onedrive.live.com/?id=636DC4E8060D66A1!380&cid=636DC4E8060D66A1)
"v1.61 NFB" indeed works nearly as expected. Only one (and a half) issue are left to my notes:
Please note, when you see "not playing (OK)", this means is not an U16 issue. There are other limitations like interface speed/specification or DAC specification.
Please also note, that I had updated Aries Femto and RME ADI-2 Firmwares, since the last tests. Not sure, if this had an effect, but you never know for sure...
So all in all it look quite good. Will continue with U16. Hope it will be stable.

"v1.61 NFB" indeed works nearly as expected. Only one (and a half) issue are left to my notes:
- Using (HDMI/IIS)-> AudioGD R7 (IIS input) at PCM/176/24 music is sometimes distorted. Not distorted like in the past, when I needed to tear the cans from the head quickly, but clearly the music is badly effected. The problem can be solved by switching inputs on the AudioGD R7. It looks like a kind of sync problem. Anyhow there are no issues at all with Singxer SU-1.
- No RME Bit-Tests for 192kHz came through. The RME can not even establish a sync to the U16 for the test files. Strange! The other 96 kHz and 44kHz RME Bit Tests where past without a problem with all bit depths. Again on Singer SU-1 also the RME Bit-Tests for 192kHz passes. However, this is a more theoretical test,I did not discover issues with 192kHz music files so far.
Please note, when you see "not playing (OK)", this means is not an U16 issue. There are other limitations like interface speed/specification or DAC specification.
Please also note, that I had updated Aries Femto and RME ADI-2 Firmwares, since the last tests. Not sure, if this had an effect, but you never know for sure...
