Kingwa forgot to put the news about the DI-V3 2014 firmware, but we can download it from here:

In the manual says that we must use firmware 2014 with driver 2014.

 

I already sent and email to Kingwa asking about the driver 2014 for DI-V3...

DI-V3 can use the Driver 2014 (24bit only)...

I have the Audio GD DI v1 and PSU v1.


Yesterday i bought a DI v3 and with a bit of luck I receive it today.

 

I have a question about the PSU however.

 

On the website of Audio GD I read the following. For old PSU v1 : Addition one 10 ohm / 0.5W resistor

 

I am not a electric engineer, but I hope I understand it. I think I have to replace the current one with another one. Right?

 

LEAD Technologies Inc. V1.01


I think it is the part I marked with arrows.

 

Can someone explain to me why I have to replace it? The output stays the same, so I do not understand.

 

Hope that someone with more knowledge can help me out.

By adding resistors in parallel to existing two blue resistors (shown as "additional green resistor" on the picture) you raise output current. Voltage stays the same.

raising current limit on DI v1 by adding resistor(s) in parallel

"Mo' powa'."

More heat too.


NOTE:
  • CONTACT AUDIO-GD FOR EXACT RESISTOR VALUES TO BE SOLDERED IN MARKED POSITION.
  • TWO EXISTING BLUE RESISTORS SHOULD NOT BE REMOVED.
  • BIG 0.5W BLACK RESISTOR (marked with red X on the picture) SHOULD NOT BE REMOVED OR CHANGED IN ANY WAY.

I can follow you thanks :bigsmile_face:

 

Still one question. Did I pick the right part (see picture in my previous post) or is it the blue one left of it. I am in doubt....

post #3997 of 4126
Yes, you were right...

I checked back my notes and correspondence with KingWa and fixed accordingly my previous post: Resistor(s) should be added to two existing blue ones... big black one should not be touched.

Thank you so much. This helped a lot.  :bigsmile_face:

New DI coming

post #4001 of 4126

Looking on the site - it does not look like I can add an AES output.  I wonder if it's possible to have: 1 - AES output, 1 - BNC output and 1 USB input?  Does Kingwa respond to this thread?

post #4002 of 4126

Audio-GD's new DI-2014 details are up, they'll be shipping out early August! It looks like the biggest changes here are:

 

1. DSD output via I2s (but not SPDIF)

2. The PSU has been placed on-board and only comes with this option

3. The PSU around various components have been built up even further (primarily around the USB chip)

4. Shorter signal transfer lengths

5. No power transfer via USB cable, signal transfer only

I like what I see!

Hi guys,

I sent the question to Kingwa, but he's not available right now......So in case anyone would know....
I have the REF5 I bought in 2012 I believe... I am using the DI 1 bought at the same time....

Would the DI 2014 improve the sound of the REF5 (the maximum the REF5 is 24/96).

Just wondering

Thanks

Denys

Kingwa would know, since no one has tested it yet.

 

In blind tests between FLAC 16/44.1 and 24/96 you will hardly find any differences, so higher than 24/96 is overkill and will not be noticed at all. The differences have to do with jitter more than anything else.

So I believe my question should be.... Will I hear an significant improvement between the DI 1 and the DI 2014 to justify the purchase of the DI 2014.
I know the REF will not read DSD file.....but I am not too concerned about that... I'll wait for Kingwa's answer then...
