@WolfX-700 posted some measurements in his website including the new products from Topping I was not aware of.

The U90 is a digital to digital converter, from USB to AES-EBU, I2S, coax and toslink.

The HS-01 looks like an USB filter that uses external power.

Edit: great HS-01 review with measurements.

Hi,
do you know when those topping hs-01 and topping U90 will be available for consumers.
I would like to buy the hs-01 better today…

Thank you for your post!

The U90 is already available for purchase.

I'm hoping to know more on it before I pull the trigger.

I'm torn between choosing an AES output or just get the Topping d30 pro cause it has a preamp and my speakers (s3v) don't have any physical volume control (and my concerns are mainly safety)

Is the U90 a two channel or four channel device? It has 2x AES, coax and optical outs; are they just copies of each other?

I think 2 channel only. Some DACs accept dual AES-EBU, one per channel (dCS comes to mind).

I am a bit disappointed. So this U90 only converts USB into various outputs but it does not allow to use these as additional inputs?

Customers have returned Topping DACs because they weren't compatible or subjectively "sound good" when pairing with USB interface from other companies. So Topping were like, screw it, we might as well just sell you our own USB interface.

These ADUMs only go to 12 Mbps.

A direct competitor would be iFi iSilencer+.
I suspect the benefits of iFi iSilencer + will be the same as iFi iPurifier S / PDIF. The noise will not disappear, only your $ 50-60 will disappear.

I got both my HS-01 and U90 today. Bought from Shenzhen, China. Delivered by DHL Express. I live in Sweden. Took about one week from order to delivery. HS-01 is really easy. Just plug in and play. I am struggling with U90 IIS protocol to talk with my D90 MQA. Almost there… Both works as expected

How is the u90 does it improve on d90 as both used as318-b clock?

I wonder what isolator chip they are employing in the HS-01.
Maybe I am not seeing it, but I can't find if it allows powering of devices without external power. It seems to indicate that external power is required somewhere, either a mains powered DAC or plugging in a non-grounded 5v PSU.
It seems quite a decent price for USB2.0 isolation.

Not sure if this what you are looking for
But I goes it looks like if your device is not usb powered or have external power then you don’t need extra power for hs01?
