Very Sensible Audio Advice
Zero Fidelity - Do you know this guy? I came across his channel on YouTube and I thought he offered some very level-headed advice and product reviews that would be helpful to a lot of people here. He doesn't immediately look the part, but I think he knows what he's doing. I would like to say it's good advice for those starting out, but I think many of us can take a lesson from him.
