Article: Sonore microRendu Review, Part 1

[scintilla]

I'm having a hard time grasping what real-world improvement this could make over a direct-connected USB input to my DAC from my iMac, which is in another room about 15ft away. Doesn't an XMOS interface offer some electrical isolation already? Is the claims that a modern computer is generating so much noise that leakage though USB/firewire ground plane is going to reduce fidelity by a great degree? Teach me here, I'm open and I have a run of CAT6 going to the system, for the SBT already. I gather I could just use a hub with the existing network cable in order to provide a path to both the SBT and optionally to the rendu for Roon/HQP use. Aren't there opto-isolators on the market for USB that would accomplish the same thing?
