U can use a USB hub but the usually degrades the sound a bit due to more complex wiring. There are no audio grade USB hub that is of reasonable cost.

ok so it looks like I manage to load the new FW for the USB now with the USB cable, was using the blaster all along, idiot. Now I have to update the FW for R7 to play DSD properly but seems Kingwa does not have the FW for the older R7. Not sure. Awaiting his reply.

Opps so I have been Doing this wrong all along. I will try usin the USB cable to connect ans see how that goes.

Well I am using mac, already running Win 10 on bootcamp so I need to upgrade to win 11 I guess

ok ao win 11 or Win 7 ??

I am also using Win 10. So win 11 is better?

Do i keep pressing the button and turn it off? I opened the device and the button is wired/connected. The usb cable u mean the usb blaster connected to the port? Is the button supposed to light up red?

Hi, I am trying yo update my DI20 to allowDSD via linix. The firmware update is now very complicated. I am supposed to “erase device” by pressing this button for 2 sec next to the update port? But it doesn’t work. Still cannot update now as I cannot erase the device. Anything I need to do?

Not sure. I know some of my DACs need the vBus from the USB to handshake but others not. Maybe only those with separate power to USB input in the DAC can do the handshake;

Maybe it is for USB handshake with other devices?

AES you can use a longer cable, and I2S you can do up to 24/352 (DXD)

What type of OXCO clock are you using ? So it beats the internal clock of the DI-20 ?

right, I have an Audio-gd R7 NOS and also can do OS (oversampling). NOS is not over warm at all, when done right. I decided not to. get Metrium due to. some comments of it being on the warm side. I think one can help balance the warmth by using silver cables (which. I use) in speaker as well as...

The DI-20 is breaking in more now. The raw edge is less so on HDMI which has been a bit more so before. BNC via ACSS is sounding quite smooth and brighter than my DH lab AES cable (but it it copper). HDMII is definitely likely the winner when all burned in. But the other options do offer nice...

DH lab do make great cables. I have their USB and Optic cable. The optical cable is particularly nice, can beat a RCA SPDIF cable, I was planning to perhaps try their HDMI but I am thinking more of either wireworld or Chord company now

yah, I have. Oyaide Solid SILver BNC and RCA cable. Unfortunately they don't seem to have the solid silver HDMI any more

Note the silver sonic is siiver plated only, Oyaida is solid silver. Also King-Wa. states the input RCA cannot be switched to BNC due to size issue in the small space. I wish the BNC clock input can be used but surely it is not the correct connector. BNC input would be quite useful you have a...

ok , yes it works! Now I am using my BNC cable from to R7 direct. I don't think Magna realize the ACSS is BNC, and Kingwa did not tell me the ACSS is for BNC, when I asked him about swapping RCA for BNC, though he probably think I was concerned about the input only. For strange reason most high...

OK, does it mean that one can use the ACSS as BNC (the connector looks like BNC) and connect straight to the R7 or other DAC and should work ?

I think eBay sells some Oyaide solid silver RCA/BNC terminals, you can certainly custom make a RCA/BNC terminal. I have the factory stock oyaide solid silver BNC - very nice and I use an adaptor to make a RCA end if needed. Then. I also bought Oyaide Solid silver RCA version for my DI20 because...

regardless of what ACSS is, there needs to be a DAC that accepts it as digital input, I think that link might have listed some that has it. I am not sure if Kingwa put ACSS digital input on his DACs ? My R7 doesn't have one. So what is the point of putting ACSS if hardly anyone can use it ?

You can simply use an adaptor RCA--> BNC to connect the RCA/SPDIF output of the DI20 to the Hugo. You will lose the benefit of BNC. Alternatively you can output via AES from DI20 to the BNC via transformer. The former is likely more straight forward and probably. sound better. I have no idea...

I see, presumably Rpi4 is Windows based ?

Are you using Win ? KinGWA said the current stock FW is not supporting Linux for DSD. I would need to load one for it) but he is now working on a new improved FW that would support Linux so let's see.

NO I setup native DSD, which works with USB direct to R7. DoP also works.
