@mdalton so you're saying that the issues regarding the power supply and other distortions from the streamer can be boiled down to SNR? What about clocking issues? How is this measured through SNR? I think people try to oversimplify things too often but your approach may be valid if somehow clock offsets can be measured properly through SNR.
OP, you are on the right track. Don't let other people get you off the rails. Just test twor three competent streamers in your system and let us know your thoughts! I'd personally really love to hear which one works in your tube based system. Good luck homie!
