RSA720 USB HUB doesnt work

Looking at the instructions. It shows the Rs130 being connected to the RSA720 via SFP modules and optical cable. What purpose would it serve if not to send sound out thru the HUB into the DAC via USB 2.0 B? It’s ridiculous really. Apparently some have gotten to work by pure luck. My RS130 never sees my DAC when connected thru the HUB

Well, i wondered the same. Rose advertises the product “to block vibration and electrical noise from external storage devices”. I was considering to get one but have no use for it if it does not work properly with a DAC.

I cannot recommend this item. It’s beautifully made. Just doesnt work the way I thought it would

However, once it is working, it is a great little device that it performs much better for sound quality than my third party USB hub with SFP.

Ive tried every configuration i can think of. I even used a new cable in case that one was damaged. I turned to components on in different orders. I swapped the SFP modules. Ive spent probably 7 hours of trying to get this to work. The RS130 throws up the DAC not connected message and to retry or not use.
No matter what I try it doesnt work. It shouldnt take this long to install the SFPs connect via optical cable power the hub…turn on the RS130 and DAC. Like 5 mins tops…not 7 hours. The fact that the customer service folks havent said anything is pretty telling. It’s a bandaid piece of gear that doesnt work

If it is meant to work with digital storage devices, e.g a NAS, then perhaps it simply is not meant for DACs. That could also explain why the DACs are not found by the RS130 connected through the HUB. Would be nice if someone from Rose could enlighten us.

I just read that RSA720 should support a DAC as well although Rose only mentions storage devices. So perhaps I consider getting one once people confirm that it really works. I have now connected my DAC via an AQ Diamond cable and the sound quality is very good already.

@paqua :Would you please try to reset RSA720? I didn’t reset my 720, I didn’t know how I made it work on one of the USB2.0. The second USB2.0 is still not working.

Mine is working well with my DAC. I guess for once I got lucky. I do have a SSD attached as well. I do have to turn my DAC on first then the Rose 130 for it to work. I can’t explain why it works but it does. I do feel your pain when it t doesn’t.

And if a problem was to be had I have had it. So lucky I am with the RSA720.

I reset the RSA 720 using the button next to the USB/SFP switch. Ive done it a few times. Ive turned all the electronics on in every conceivable order you can think of. I bought a new cable even and nothing. So, I have sent it back. Is there another USB hub that does the same thing? Anyway… 2 days of headache is now gone.

Not that I know of that support audio out for DAC support.

I was really looking forward to this HUB. Ahh well

Before you give up see if Hfi Rose fixes your issue with the next software update, could be as easy as that.

HUB is already enroute back to vendor. HiFi Rose didnt bother to speak up at all on this thread. They dont seem interested at all

Where did you purchase it? Did they attempt to help you?

I spoke to them. They admitted they havent used one of them before. So they had no real input other than what the instructions says. The Music Room was the distributor. They were as helpful as they could be
and sent me an RMA and shipping label as soon as I asked. I was all in with this HUB …it looks amazing but it is poorly implemented. The fact that most have nothing but trouble with it is proof. Maybe in the future if they decide to address it and patch the RS130 I may go for it again. But Ive exhausted all ideas and possibilities. I have HoloAudio Spring 3 KTE DAC. It’s not cheap by any stretch. The RS130 sees it fine when I use USB. Even works with I2S.

Is there a switch to turn the device off or do you have unplug it? I guess there is no standby function then?

No switch to turn off. Yes you need to unplug to power off. There could be an auto standby mode but unknown as there is no documentation that details that feature. @ROSEHAN or @ROSELOA can you comment and also discuss why other users are facing challenges. Is HIFI Rose seeing these issues themselves? Is this a hardware issue or software issue. Your input and customer support is needed.

I believe I2S is the way to go with that particular DAC. That way you could also benefit from the excellent clock in RS130

@duffer5
Which DAC do you have?
