PS Audio founder and CEO, Paul McGowan, writes a daily blog: short, informative, fun, often controversial, but always interesting. Subjects range from personal stories, how to setup your system, news of the day, streaming, vinyl, tubes, transistors, loudspeakers, holographic imaging and more. Kind of like the Car Talk of audio. Not much is sacred, and there’s rarely a mention of our own products.
