I’ve got the Allo USBridge working perfectly fine at the moment with HQP DSD512 and DSD512x48 using the Allo supplied USB-ethernet adapter on Sparky’s USB2.0 port.
I have issues with DSD512x48 on Sparky’s ethernet port (stuttering). It’s ok with DSD512x44 but I need DSD512x48 working so I scrapped the idea of using Sparky’s on-board ethernet.
Like some others on the CA Forum I have issues using the Allo supplied USB-to-ethernet adapter on Sparky’s USB3.0 port.
But the USB-ethernet adapter works rock solid on the USB 2.0 port of Sparky.
I have USBridge is streaming to the new iFi xDSD (5Vdc externally powered). The USBridge is quite happy being powered by a USB3.0 port (900mA).
Tested with Roon + HQP (obviously) but also with mConnect and BubbleUPnP playing direct to HQP Embedded > USBridge NAA.
This is an important note by Allo for Roon + HQP:
A nice HQP NAA. Very smooth sounding USB source, which makes me think (guess) Allo pay attention to good RF filtering before the output.
