Allo USBridge Signature

Hi all,

I am new to the streaming world. But, I figure I would try some streaming options. I currently picked up a USBridge Signature from Allo running Volumio OS. I would like to hear what is the opinion about this product ? Is it comparable to off-the-shelf solution like the UltraRendu or the SMS Ultra Neo or the Zenus ...

I am currently running the USBridge with Shanti power supply and is quite please with the SQ result. Just want to see if I change to other streamer, should my Sound Quality improve further or should it stay the same. I am using Roon by the way. Thanks for your helps in advance. 

My system: KEF R5 , MC352 amp, Audio Research LS25 preamp, Chord Qutest DAC, AudoQuest cables, USBridge Sig streamer.
