Please send me the rsa 720 firmware update to my email at kchong88329@netvigator.com. Thank you!
I have sent the RSA720 update file and instruction manual to your email address.
Please let us know which part cannot be updated, and also inform us of the results after completing the update.
Dear Seong Han,
Thank you for sending me the update file, I am currently in China right now, I will let you know by this weekend regarding what works for my RSA720. Thank you!
Best Regards,
Eddie Chong
At the begining of the update, I have trouble getiing my computer to recognized the drive, the vl810filter.sys was block by the windows security due to non secured driver. But at last, I have solved the problem by editing the registry in order to make it work. I successfully updated the firmware for both usb 2.0 ports sucessfully, but the version of firmware you sent to me was 82.00.42.00 instead of 92.00.42.00 shown in the manual “How to update RSA720 VL671 FW.xlsx file”. I am not sure of you sending me the latest firmware updates for my RSA720?
After I have successfully udated my RSA 720 firmware, I am still having trouble connecting my gryphon diablo 300 DAC to my rs 130 via rsa 720 usb port 2.0 connection. The sfp connection within the rs130 in/out setting still cannot find my diablo 300 DAC. The sfp connection dialog box still showing No DAC found, please try again message.
Does the AES or Toslink direct connection from the RS130 to the Gryphon DAC work?
I don’t have cables connecting the AES and Toslink from rs130 to the gryphon DAC. But the connection works from RS130’s audio usb-a to Gryphon DAC’s usb-b.
I am glad to hear you can get sound out of it to enjoy. Does the USB convey the resolution from the 130 to the DAC that you desire?
Yes, it does sound quiet good.

Once connected via USB to your Dac, through the RS720 connected via optical to the Rose 130, in the RS130 settings connect to the Dac with the USB toggle instead of the SFP toggle. That worked for me.
I went to my dealer for an exchange for a new RSA 720, due to the power supply is not powering up the device properly. After I plug in the new RSA 720, I finally got my RS130 successfully recognize my Gryphon Diablo 300 DAC via a USB2 port on the RSA 720 (with SFP toggle).
As described in the link below, if updating the RSA720 does not resolve the issue, we can provide an additional solution.
Based on that, we can send you a customized module that includes the latest compatibility improvements.
Please refer to the following post for more details:
Thank you for responding to my issue regarding connecting my RS130 to my Gryphon Diablo 300 DAC via RSA 720. The problem was after connecting my RS130 to RSA 720 using fiber optics, then I connect my DAC’s usb cable to a usb 2.0 port on RSA 720. Then I try to configer my DAC within the RS130’s output setting. After numerous attempts, the RS130’s output setting still showing no DAC was connected. I also have a power connector problem with my RSA 720, the power connector on my RSA 720 won’t stay power up, so at last I went to the dealer in Hong Kong and exchange for a new unit. I also updated the firmware on the new RSA 720, then I try connecting the RS130 and my DAC via RSA 720 again. This time the RS 130’s USB port output setting has recognized my DAC.
The following pictures shows the connection I made with my RS130, Gryphon Diablo 300 DAC, and RSA 720.
Please also send me the customized module that includes the latest compatibility improvements on my RS 130, DAC, and RSA 720. Thank you!
If you require the RSA720 SFP Kit, please send your request along with your shipping address to the email below:

We have checked our inventory, and unfortunately, the production team expects to have additional stock available in approximately 2 to 3 months.
Would it be possible for you to contact me again in August? Once the stock becomes available, I will make sure that the SFP Kit is arranged and shipped to you as soon as possible.
Thank you for your patience and understanding.
O, no problem, I will contact you back in August. May I ask what is the SFP kit included? Thank you!
This kit consists of two high-performance SFP modules and a dedicated optical cable, minimizing signal interference and latency to achieve lossless digital transmission.
As a result, it enables clearer and cleaner audio signal delivery, maximizing the overall performance of your audio system.
Thank you for sending me the photo of the updated SFP kit. Please let me know if the kits is aviliable for delivery. May I ask why the SFP kit come with single core single mode modules instead of dual core? I am connecting my rs130 and rsa720 using SFP+ dual core single mode 10G modules (Finisar FTLX1475D3BTL). The sound has improved dramatically.
Modules Finisar lasers are better than modules HiFi Rose lasers, I think, and of higher quality! The result is much faster detection and more transparent sound!

I will let you know as soon as the kit becomes available for shipment.
Just to be safe, could you please contact me again in August? Our production team is currently working on securing additional SFP kit inventory.
Thank you for your patience and understanding.
