@tjag The above experience isn’t definitive in streamer vs reclocker superiority as the Chord MScaler doesn’t have optimized usb board, really meant for BNC input. I bet tables turned using dac with optimized usb board.
You stated the following: "as the Chord MScaler doesn’t have optimized usb board".
Please define what you mean by "optimised USB board" and provide references (links) to your statements, otherwise your statements are not verifiable.
In the the M Scaler manual both the DUAL BNC & USB INPUT support the same highest sampling rates. Check section "Output sample rate settings 4.5"
The M Scaler USB is supported with galvanic isolation. Here is what the M Scaler manual states:
Galvanic isolation 6.2
Galvanic isolation involves isolating the power rails of the data USB input, allowing for greater sonic performance.
The Hugo M Scaler features a Class 2 Type-B USB input with this protection. Galvanic isolation also features on the dual-BNC outputs.
