In a recent episode, hosts Darren and Duncan talked about a system's ability to collect and drain RF interference through the connected enclosures and low-impedance paths to ground. In this show, the guys -- and Darren specifically -- drill down further into high frequency bogey man land. Are modern chassis boxes even good at being faraday cages? How do designers maximize effectiveness in removing RF from a circuit, and what about tubes? Lots of questions answered in this fairly geeky episode of The Hifi Podcast. Stay tuned, because the album of the week is jaw-dropping.
