I just found 3.993 this morning with no explanation other than here it is and give it a try. SPDIF input is an issue on some DI's so will try that this morning with 3.993.

Kingwa released yesterday's 3.99 on the AGD web site.

Version 3.99 at least has issue on my two DIs. SPDIF in no sound. Version 3.93 is normal.

Try 3.993. It's in the 3.99 rar file.

Cables are good?

I think 3.993 is just bug fix attempts perhaps. Kingwa just said "here it is and give it a try".

SPDIF input in parallel mode has always been an issue on my DI20HE. Switching to serial seemed more stable. 3.99 played OK (parallel mode) with only two minor dropouts in 2 hrs of testing. 3.993 SPDIF input parallel mode does play on my DI20HE (parallel mode) so will run this for several hours to test. I have the Singxer SU-1 drving SPDIF input.

I’m on 4,5 weeks burn in and my unit (90/98 version) has taken a big step forward from being somewhat edgy with (too much) openness in the midrange (resulting i mild ear pains after 10 minutes of listening) towards a much more balanced and natural presentation with the bass impact being slighty less (in a good way as it was too much before).

It is quite strange how the sound changes during burn in. Hoping so much that this is a permanent step in the right direction and that the edgyness will be gone permanently.. fingers crossed

 

[DACLadder]

@Oepsie Yes it does take a while to burn in. Probably 700 - 1000 hrs. Good things will evolve slowly.

 

[FredA]

The first 350 hours can be a bit painful cause sound quality varies much. After that, it will improve slowly up to 1000h.

oh I remember the first couple of days when the bass was overblown (or more likely my treble didn't wake up yet)

What's your DAC?

 

[Oepsie]

An electrocompaniet ecd-1. So an old one with little filtering..

what chip/s in it?

I’m enjoying 3.993 f/w. USB in/ I2S out/ parallel mode, int. or ext. clock. I’m getting much less grain/ glare. First thought the f/w had less highs but it is just less junk. More depth... spooky compared with 3.99 yesterday. Large space. Bass is thundering as well. Worth a try if curious!

 

[Wynnytsky]

I don't know what it's like for others but when I engage my clock (w/ di20he 3.993 only) the dynamics rise to the point where I think I'm listening to a delta sigma dac. Though it's a little drier, it doesn't exhibit that hard+thin sound that is so typical of delta sigma implementations.

 

[FredA]

Yes, i think i prefered 3.99. Or 3.98. Good sound with 3.993 but i could use some syrup. Some meat. Bacon in maple syrup, just bits. And just a little syrup.

 

[Toni-Mang]

DI-20V4.07Beta1 is out...

 

[DACLadder]

Yes it sure is... 4.07beta1 adds DoP 64 capability to SPDIF output. To use the capability you will need DoP firmware on your DAC.
