In this episode, a listener requests a deeper dive into room treatment for optimizing sound in a HiFi listening space, and the fellas oblige. In fact, Darren and Duncan leap at the chance to talk about the curious look of some commercial treatment products, bemoan the high prices of some seemingly cheap-to-develop elements, and generally touch on many important elements of the entire equation. The Album of The Week this time hits a different genre than usual, with a record from one of the top modern choral groups recording today.
