300B Audio Tube Mega Shootout 2026: Objective Testing

There is an objective part, where I run these tubes on my Analog Discovery 2 with the Audio Analyzer Suite to look for the differences in measurements that I heard. I also give a subjective review with my latest 300B amp in my updated listening room using Quad 5 speakers. Found some interesting things, no spoilers, watch the video :) There is so much hype surrounding this tube, it's past time to get to the bottom of which of these are the real deal, holy grail audio tubes!
