I am disappointed that there is no toslink optical port. I found it to be great as it eliminates every interference from my PC to my DAC.

I have seen a post in bbs.audio-gd.com years ago, comparing the coaxial and optical SPDIF inputs/outputs that the coaxial ones have much lesser jitters than the optical ones when the lengths are short, but for the longer connections over multiple meters, people should choose optical ones other than coaxial ones.

Check your original packaging if you still have it, he included one for me so I assume it's standard.

(I actually bought one off eBay before finding the one in my original box doh!).

Wow ok I'll check! Kingwa told me to buy off ebay though so I Assumed its not there?

Well, I don't think I will be able to hear jitter differences. The point is that if i use coax out of my pc, I hear interference. With Optical everything is fine. Would choose a Mutec 3+ USB, but it lacks I2S

*** New DI-20 Firmware 3.93 - June 2020 ***

Kingwa has released new DI-20(HE) firmware (3.93). He has been playing with his new Mutec Ref 10 external clock and has provided some positive enhancements. He told me that 3.93 improves the sound quality with other 10M clocks as well. And also enhancements to HDMI I2S internally or externally clocked.

I think we are starting another productive firmware period so if you want to wait there may (will) be others to try shortly. Kingwa is looking to further improve the timing of SPDIF outputs in another future release of firmware. And I like the 3.93 firmware. Clarity improves (less fuzz), soundstage, bass strong, mid-range texture.. Enjoy! (@Wynnytsky)

does the DI-20 update guide need to be updated?
there is no alters 12.1 web edition to be downloaded. Please clarify.

 

[Toni-Mang]

Imho the new Firmware is stable now in P mode...perfect soundstage, no shift.

That version of Quartus SW (12.1) is obsolete and most definitely all documentation needs to be updated. On the Audio GD f/w download page, there is a OneDrive cloud link the download 16.0 Quarus PC software (or click below). Just choose 16.0 Quartus 64 or 32-bit version. Download and PC install. No license required. Be sure and answer ‘yes’ during installation to install USB drivers for the Blasters. 16.0 has more modern Windows ‘look‘ but functions basically the same as 12.1. We are here to help. First time use setup is intimidating but ‘old pro‘ in no time.

Thank you

My two DI-20HE is updated last night.
SQ is improved.
SPDIF input and USB input's SQ is very close.
The SPDIF input with occasionally sound image shifted seems gone, still need more test.
I have issues with SPDIF input when using internal clock. The sound is choppy when sampling rate is 48K & its multiples. However its OK when using External Clock.

Thanks Kingwa for all his work. My Reference 1 (i2s in mod) with DI-20HE is still serving me very well. The other DI-20HE connects to my R7.

Hello, after replaced the USB cable between the streamer and DI-20HE with a 5N silver solidcore USB cable with JSSG360 shielding, I give a order for both ACSS cables with the same cable and shielding. Today I received the mini XLR, the 4. pin XLR is unclear

Now I have the question how is the 4. pin of the XLR ACSS connected? Adding a 4. cable?

Many thanks in advance!

 

[JaMo]

XLR stands for X= Shield, L= Line (+), R= Return (-)

Audio-GD's ACSS 4 pin XLR's use pin 4 as an additional shield So... pin 1 Sheild, pin 2 Line (+), pin 3 Return (-), pin 4 Shield.
No forth cable. Just bridge pin 1 and pin 4.

I you dislike programming the FPGA wait a while as there will be other versions coming soon... SPDIF input glitch, SPDIF output timing, and external clock bugs addressed.

 

[jimmychan]

I have just tested 3.96 & 3.98, that both has no sound with SPDIF input.
I fall back to 3.93, SPDIF input works ok with Ext. Clock.

 

[FredA]

Firmware 3.98 is out.

Too soon to make a definitive call on it but the spdif gltich i had seems gone, yeah!

Also, using the external clock with 3.93 in parallel mode, there was a lack of punch, and the soundstage had shrunk, now things seems to have gone back to normal while the resolution gain of 3.9 seems to remain. Maybe still not as punchy, i have to listen more and under better conditions, it is noisy now in my room.

Too early for champagne but so far, things look great. The di20he has such a good architecture that further future enhancements are likely.

 

[DACLadder]

Yes, there is newer firmware today. Kingwa is releasing faster that we can test. YMMV

What I found..
3.93 - Several of us are having issue with USB input, external clock, and parallel data mode. Sound level is lower and not dynamic comparing to serial mode or previous 3.9a.
3.98 - SPDIF input - dropouts especially in parallel data mode. USB input/ parallel mode/ ext. clock sounds better than 3.93.

Kingwa is going to be busy when he returns from holiday. And please report bugs to Kingwa.
