Last week, we posted a video on AudioStream of a conversation between Juergen Reis (MBL's Chief Designer), Michael Lavorgna (AudioStream), and John Atkinson, which we filmed during CES 2017. During that same session, we also filmed a conversation between JA and Juergen that focuses more specifically on MBL's new N31 DAC, which JA will be reviewing in a future issue of Stereophile.

In this video, Juergen and JA discuss digital filters, aliasing, Nyquist ringing, USB inputs, inter-sample "overs," and many of the other arcane issues involved in DAC design.

With their matching wide, distinctly un-stylish yellow ties and dark blue suits, the men of the Sibelius Piano Trio hardly look like world-class musicians. But once you hear their two-CD set from Yarlung Records, best appreciated via stereo and multi-channel DSD downloads from NativeDSD.com, you'll understand why their debut recording of trios by Sibelius and contemporary composers deserves a place in your collection.

Never in the history of our venerable "Records To Die For" feature has the word Die come to mean as much as it has in the past year. Merle Haggard, Phife Dawg, Rudy Van Gelder, Maurice White, Glenn Frey, Otis Clay, Blowfly, Bob Cranshaw, George Martin, Steve Young, Chips Moman, Lonnie Mack, Prince, Leonard Cohen, Sharon Jones, Leon Russell, Ralph Stanley, David Bowie—all died in the past year. So to drive away any evil spirits that may be hovering over this year's R2D4 extravaganza, we may need to think of this 2017 installment more as "Records to Live For."

Saturday January 28, 1–6pm, Esoteric Audio (111 West Monroe Street, Suite 100, Phoenix, AZ 85003) is presenting the first public showing of the DS Audio DS 002 Optical Phono Cartridge System. This is a lower-priced version of the DS Audio Master1 that Michael Fremer reviewed for Stereophile in September 2015.
