RSA720 USB2.0 Connectivity Issue to DAC

I think we need to ask Hifi Rose have some accountability with software engineer in charge why these problems continue to persist, and when will be new leadership to create world class, problem free software we expect .

the solution I have specified no longer work after upgrading to latest firmware… I am so so so tired to follow this up, so I simply using audio usb port from RS130 to connect my DAC directly, and start evaluating if I should switching brand…

Please don’t give up

Yes @Bicycle, don’t give up @deckard
I don’t have problems with the USB hub to my RS130.
However, I lately switched to use I2S between my Laiv Harmony Dac and RS130.
The sound quality, IMO, is as good as using USB via the RSA720, though a little different in presentation.
Surely you’ll need a good I2S cable. The one I am using is a 0.75m 7NOCC cable about USD100. I am pretty happy about the sound from this connection.
At present, I mainly use I2S and switch back to USB for comparison only.
If your DAC supports I2S, worth a try, no matter if you have problem with the RSA720 or not.

Once you overcome the challenge, there’s immense joy in using the hifi rose products.

I’m interested in buying Laiv harmony dac. How is the performance compared to weiss 204?

I would say it’s better, compared to the memory I have with the 204. Of course, others may have different opinion.
The Harmony Dac is a pretty good device.
You can see my first impression with it here: LAiV Harmony Dac - #30 by TomT

I have RS130 and RSA 720. I can not use SFP connection anymore after the latest update. Now I have to use USB connection to RSA 720 and my Weiss DAC 204. I can tell that for sound quality, USB connection is not as good as SFP.

Therefore, I have ordered RD160, hopefully, it is my end game DAC for this system.

I agree with your assessment of the LAiV Harmony DAC. I use the I2S connection with my RS130. However, I also have Roon and run Baach through the USB input on the LAiV Harmony for comparison as well. It’s interesting. Each one is different. I wouldn’t say one is better than the other, they are just different.

Sorry to hear that. Yes, the RSA720 is indeed not good for all devices.
The RD160 should have avoid such issues.
I was keen on getting the RD160 as well, but sadly still no exact date of its release in my country.
Let us know how it sounds when you get it.:wink:

Yes, the I2S and the USB with RSA720 sound differently on the Harmony DAC. And I think it’s fair to say that I cannot simply tell which is better than the other.

Not sure about other Dac, but with the Harmony DAC, I can hear some music are better with I2S, and some are the other way around with USB and the RSA720.

In a way, the music from I2S is richer but more airy from the USB. So I would say they are both as good.

I currently choose I2S because it suits my taste more these days and I am a bit lazy to switch back and forth.

Having two similarly good connection choices is good and fun, isn’t it?

I highly recommend Denafrips Terminator Plus Dac. It has a very warm, very musical, very organic and very realistic scene. I have some videos but you can’t hear the scene from the videos. You can only feel it. If you wish, you can watch it on “Youtube: Tweakhane” channel. Denafrips is a device that can be the last Dac of a system.

Did you have success connecting it via Rose RSA720?

May I know the price of Terminator Plus Dac ?

Thanks @TomT Unfortunately, my DAC does not support I2S… But I agree RSA720 to connect my Weiss DAC give better SQ compare to direct USB output from RS130

Right, the Weiss 204 doesn’t have I2S. And indeed USB via RSA720 gives better sound quality. Sorry for the issue you’re facing. It is really annoying.

You can check the “Terminator Plus” prices for your country online.

After the latest update, I too can’t connect my Holo May KTE via USB to the RSA720 w/ SFP connection back to the RS130. Anyone found a solution yet? FYI @Yu3319 ROSEHAN @ROSELOA

I have asked @Roseloa for a firmware update for RSA 720, I have not heard anything back yet. I believe that the firmware update on RSA 720 might not work, that could be the reason for the no response.

I gave up on RSA720. Hopefully, RD160 will work well with RS130. However, I have seen any reviews yet.

Any idea when RD160 will be available in the US? Only 10 more days left in Nov.

I was able to get my DAC recognized after a series of reboots across both devices. Now I am keeping my DAC and RS130 ON at all times to make sure it stays connected. Not very green of me but it’s working so far… I do think we need HiFi Rose to step up and make this more stable.

I also have the latest firmware they mention (they keep sending me the same one). Happy to share that with you? DM me your email.
