But to learn about new music I want to buy—old-fashioned I know but I do believe musicians deserve to get paid more than fractional streaming pennies—I cruise YouTube, Spotify, Tidal and Qobuz on the work desk so agreed to take Fidelizer's modded Cisco for some streaming bends. And for certain reviews, the main system is set up to stream, including support for tablet remotes which then involves activating short-term Wifi and the brain irritation of microwave radiation which, for us, stems from it.

This wide steeply toed-in setup provides the bigger deepest staging as though the big monitor screen wasn't even there.

Here's a quick drawing of our fully wired LAN to show where the Fidelizer would insert; and what happened downstream from it.

My desktop speakers' lack of USB means that the Romanian battery-powered USB bridge from Audiobyte must generate the necessary S/PDIF signal which adds its own isolation and reclocking to the HP Z230 work station's USB output. I wondered whether that'd make the Fidelizer redundant. In the big system, Soundaware's D300Pro isolated from utility power by internal bank of ultra caps acts as USB bridge to provide our Denafrips Terminator R2R DAC with I²S over HDMI as the best-sounding digital interface trailed by AES/EBU then coax. But because the Terminator has its own USB input, here I could easily eliminate the USB bridge should I otherwise fail to distinguish between our TP-Link 5-port Gigabit switch and Fidelizer's. If that still netted no results, I'd compare the latter to running the 30-meter CAT5 cable direct into our iMac. In short, going in I had no idea what to expect but did lean to the side of low to no expectations. That's because our post-USB reclocking and noise isolation had proven itself so effective already. Could multiple clocks in series really make an audible difference? Was wired Ethernet's galvanic isolation sufficiently lossy to pass enough noise to warrant special treatment?
