In this week’s episode of The Hifi Podcast, Darren and Duncan focus on a couple of great listener questions. After the usual “what’s up with us, audio-wise” reports, the guys dig into the topic of how to decide when an audio product is ripe for a modification.Given recent podcast focus on tweaks and mods, and their own re-build projects involving a pair of Audio Research D-115 tube amplifiers, it makes sense that there should be some guidelines to help identify which products can be modded, and which ones should be left alone.After tackling that question, the guys move on to answer one from an old friend of Duncan’s. This DJ is focused on turning his basement into a Klipsch-powered party zone, featuring several DJ turntables and a huge collection of great vinyl from the “Deep House” genre.From SPL to sound absorption, proper cabling and amplifier matching, the guys attempt to lend a hand in what promises to be a seriously fun spot for enjoying music and dancing. Along the way they learn more about this jazz and funk-infused dance music that combines elements of “Chicago House” and complex chord progressions found outside of the traditional dance music sphere.As for the album of the week, this one is one of Darren’s and Duncan’s favorite holiday records. It features one of the absolute greats to ever touch a piano, and was recorded two years after he suffered a stroke. But you would never know that by listening… the brain is an amazing, curious machine. As always, sound quality is superb — this album belongs in every audiophile’s library regardless of the season.
