Steve M Posted April 29, 2017 Author Share Posted April 29, 2017 No I didn't play with any settings at the back or underneath. The Singxer unit belonged to Rocky who ordered it preset for i2s connection compatible with the Holodac. If you are using the i2s connection from the Singxer to your dac/Server, you will need to align the Word-Clock-Data lines in the i2s lead for the dac/server and Singxer unit to 'see' each other. Fortunately, the Singxer has switches underneath that allow you to do this. Unfortunately, there seems to be no industry standard as to how i2s connections are made with components from different manufacturers. Well, at least that is my understanding of the situation. Cheers, Steve. 1 Link to comment Share on other sites More sharing options...
PKay Posted April 29, 2017 Share Posted April 29, 2017 @Steve M thanks for the reply. I am using an AES/EBU cable so it should work. I have sent sent a query to Mr Chen from Singxer, I will also send Antipodes a query. Link to comment Share on other sites More sharing options...
rocky500 Posted April 30, 2017 Share Posted April 30, 2017 I think the Singxer SU-1 will do DOP only unless you install the latest windows driver for the Holo Dac(just to support the Singxer), then it can do native DSD. I read rumors there will be a new firmware coming for the Singxer that will alow it to do Native DSD for other OS. Link to comment Share on other sites More sharing options...

Sir Rab of Everest Posted April 30, 2017 Share Posted April 30, 2017 Currently using it with a Killerdac with a select Philips TDA1541- S1 chip playing up to 24/96 Why 24 bits, since the dac chip is limited to 16 bits...? Link to comment Share on other sites More sharing options...

zenelectro Posted May 3, 2017 Share Posted May 3, 2017 I looked at Singxer but reclocking of I2S is done inside Xilinx FPGA. Not a good idea and I'm surprised they do something like this. Link to comment Share on other sites More sharing options...

Not a good idea and I'm surprised they do something like this. Why is it not a good idea if I may ask? From all I can see in many DDC an FPGA is used on the I2S either for buffer or reclock. Gustard XMOS based DDC use an Altera FPGA. Amanaero USB also uses a Xylink also even it already uses Atmel FPGA for the usb conversion. Link to comment Share on other sites More sharing options...
zenelectro Posted May 7, 2017 Share Posted May 7, 2017 After a 1 minute google search..... Quote from a Principal Engineer, major FPGA manufacturer: "even with the -90 degree clock trick, you will not get below 35 ps P-P. If that is a problem, then you should fix the system and layout, as nothing you will do will make it any better without NOT having the clocks go through the FPGA device" IOW most implementations will have jitter much worse than this.

rocky500 Posted May 11, 2017 Share Posted May 11, 2017 (edited) I see the new firmware is out! But it is only accessible if you are a kitsunehifi customer. On his site "NEW 2017 firmware (2.22 and 2.20) for DSD512 native is for customers only and by email request only. This will support the newest OS for Sonore Urendu @ full dsd512 native!" 1.only for Singxer SU-1,support DSD512 in native.2.Do not upgrade any other XMOS device,including SINGXER other XMOS device.3.V2.20 update for V2.00; (for holo audio, Audio-GD, L.K.S.)V2.22 update for V2.02. (for PSAUDIO, Gustard, ) This will allow DSD512 only with some versions of linux, or newest OS on the Sonore Microrendu and with Windows and HoloAudio Spring signed drivers installed. NOT singxer drivers (these only support DSD256 over DOP) Edited May 11, 2017 by rocky500 Link to comment Share on other sites More sharing options...

Great way to build on his brand!!! I can't get DSD to work with SPDIF so no loss to me - but any firmware updates should be available to all.

I guess he's just trying to look after customers and perhaps capture people into buying from him. I don't think any manufacturer is obliged to give away the XMOS drivers or make them freely available. But they can't stop a Scumbag like me ferreting them out.

I agree with you I was under the impression that it is the guy who is making Singxer who developed the firmware and accordingly should make it available. I must say having sent them 2 emails with zero response - I wouldn't go recommending them for any service awards. This is in stark contrast to every other manufacturer I have dealt with where response times can range from 1/2 hour (Antipodes 2nd to none) and Naim and Meitner with 12-24 hours with different time zones. Who developed the firmware?if it was Kitsune then I have no issues with him not making it available. Link to comment Share on other sites More sharing options...

rocky500 Posted May 11, 2017 Share Posted May 11, 2017 (edited) I had to install the "Singxer-USB-Audio-Class2-Driver_v3.34.0.exe" driver on my laptop. (Windows 10) Then connect the Singxer direct to it with USB. Then follow the instructions. Worked fine with my Curious cable.

It was mainly so I can try a linux distro at some stage and it may be able to do Native DSD. Tried Roon and upsampling to DSD and get upto 256 Native but no sound when I try 512. My Dac is the Holo. I used the v2.22 and looking a bit more, maybe I could use v2.20. I think the difference is swapping left and right channels.
