I saw some comments above about only using USB1, can this handle DSD (64/128) to a compatible DAC? I use DSD exclusively via upsampling in Roon and native content.
Wanted to make sure before I buy.
Great question. Since the ethernet and USB donāt share the same bus I was hoping for even higher sample rates supported, up to Native DSD512 (if the DAC patch is available of course) .
@allo.com. could you clarify the PCM and DSD rates supported ?
Cheers

Hello Johan,
What about native DSD512 (not DoP) ?
Are you in touch with DietPi for Linux 4.9 kernel patch to allow Alsa native DSD512 playback with compatible DACs (new ESS Sabre chip equipped dacs and HOLO, T+A, Lampizator, ā¦) ?
We have many things on our plate right now. Still finishing the new custom image with Dan , some surprises 
Once everything is done will look into it but I cannot guarantee it will work at DSD 512 (native)
I really hope you will ā¦ DSD512 support is a key point for me.
Is it possible Sparky / USBridge hardware limitation ?
Seems Sonore (URendu) and SOtM (SMS-200) managed to support native DSD512.
No hardware limitations that we know ofā¦but I am concerned about the kernel patch. Basically we need to try and see.
Problem is that we have no DAC capable of playing 512 DSD on our test setup.
I understand but more and more DACs are DSD512 enabled and ALSA patches exists.
See, for example: https://github.com/lintweaker/xmos-native-dsd
Ok we will look in it
he allo/ johan
wouldnĀ“t it be nice working with ropieeee?
try talking to Harry ten Bergeā¦

I think for this you should contact Allo. Iām not gonna buy the hardware myself, and Allo has nothing on the Sparky (the SBC used by the usbridge) with respect to kernel etc. onlineā¦
could be a great coop? with roon lcd;-)

I got my Allo Sparky + USBridge yesterday. Everything Runs smoothly.
At the beginning I had the problem that the device was not displayed in my router menu (Fritzbox 7490). After I had found the address, it was not a problem to set up via Putty. Mayen this may help a little.
I would also like a web interface (which is probably in the direction of the dietpi developer). The Sparky / Usbridge is connected to my Auralic Polaris.
I got my USBridge yesterday. Hooking it up was a breeze. Roon Bridge and HQ NAA working fine and sounds great out of the box and does feel like an improvement over directly going from the PC to Dac.
I need some help getting it to work Native DSD 256 and 512.
My chain:
I am running Windows PC i7 Kaby Lake build -> USBridge -> T+A Dac 8 DSD -> Nord Hypex Ncore Dual Mono -> PMC MB2 Se
I believe a Linux patch is being developed. Checkout the Computer Audiophile forum for the T+A DAC 8 thread. Thereās been progress updates there but I havenāt checked in a while (since I trialled the T+A DAC 8 and saw it was limited to DSD128 at the time). It may be close/closer now
Thanks Sean. Looks like there is a new version out this Thursday.Iāll have to manually install it. Shall give it a try.

No not yet. Please allow us some time to test and fix bugs.
Hi everyone who use the Allo USBridge with Sparky,
I received mine yesterday delivered to my door by DHL.
I waited today with unpacking the package, everything was there!
So I put everything on place and connected it, started my computer and it works perfectly 
.
Thereās a red and blue light on Sparky and the blue light is lighting constant, but the red light is on and off with the same interval? Slowly type 2 seconds between on and off! I have looked everywhere but I canāt find anything about it, so Iām asking here if someone nows why? For example @allo.com Johan!
On the USBridge is a red light constantly on!
But I can play TIDAL Masters MQA from my Meridian Explorer 2 DAC and change to my B.M.C Pure Dac and playing 16/44.1 up sample to 24/192 and with my different DSP settings.
It works perfectly, I havenāt tried DSD or Signalyst HQPlayer yet!
I have a photo on the audio because I donāt know what is ASIO or WASAPI! Okay now itās ALSA and what is atm7059_link?
Iām a totally newbie when it comes to work or using products like this, but I have got great advice and perfect service from Allo and especially Ioan at Allo! We have had lots of email contact!
So Thanks Everyone at Allo .
Best
Anders
Please use it as 384Khz and DSD 128 max for the moment . We are still trying to see if we can enable higher .
