In this week’s first segment (02:48 to 15:52), hosts Brent Butterworth and Dennis Burger share their varied opinions on “MoFi-gate,” the biggest scandal in the analog audiophile world right now. It turns out that Mobile Fidelity Sound Lab—long lauded for their all-analog production process—actually creates their lacquer masters from 4X DSD files these days, not directly from the master tapes. Will this be the end of this revered audiophile company? Is the outrage justified? Brent and Dennis have thoughts.

Next up (16:24 to 28:15), they dig back through the Stereophile archives to discuss a review of the Monitor Audio Studio 20 loudspeaker written by Robert Harley in 1991, complete with measurements by John Atkinson. Monitor Audio is a brand beloved by Brent and Dennis alike, so this throwback review gives them both the opportunity to reflect on just how much has changed in the world of loudspeaker design in the past 30 years. 

Finally (28:50 to 39:20), they dig into James Hale’s latest “Art+Tech” column on SoundStage! Experience, in which he explores the music of Charles Lloyd through a pair of different iFi Audio DACs, including the same Zen One Signature, which Dennis recently fell in love with and added to his reference stereo system. Somehow or another, though, this leads right back to a discussion about vinyl.
