I have used both versions with both tube and SS amps and I don't hear any issues. As Andrew's primary business for the last 20+ years is in phono preamps I assumed he understood about noise and signal anomalies. His latest "statement" phono preamp just received a glowing review from HiFi +. If you hear anything out of the ordinary in your system let me know as I'm sure the AG's will reveal more than even the KO's.
Will do. I'm sure it will be no more intrusive than a volume control on the DAC in the mix.
