Lumin's popular D1 has been updated to the D2 (black unit on top in photo above) with several new features: internal switch-mode power supply (no more wall wart), dual-mono Wolfson WM8741 DAC chips, reworked board layout, and DSD 128 support. There is also SPDIF out and you can bypass the internal DAC.

Replacing the mid-size chassis offerings from M2Tech that were originally targeted to desktop and secondary system use, the new Rockstar line is now intended for main systems as well. The Young MKIII preamp/DAC features include additional digital inputs and analog inputs and outputs, DSD 256, full MQA, and Bluetooth APTX .

Master & Dynamic, known mainly for their headphones and earphones, recently launched their MA770 wireless loudspeaker ($1800 each). Designed by Sir David Adjaye, who also designed D.C.'s new Smithsonian Museum, the 35-lb speaker's cabinet is made from exceedingly inert composite concrete…

KEF has just upped the ante on the LS50W, the wireless version of its lauded LS50 bookshelf speaker, with the release of the LS50W Nocturne Special Edition ($2499.99/pair). Engineered by KEF Head of Acoustics Jack Oclee-Brown and sporting an eye-catching design by Dutch Designer Marcel Wanders—I regret that my photo fails to capture all the graphic detail on KEF's Uni-Q driver and cabinet—the LS50W Nocturne Edition will be available on January 15.

Sitting next to its big brother DAC/transport combo, Chord Mezzo 75 amplifier (75Wpc into 4 ohms, $4995), and new Spendor A2 loudspeakers ($2395/pair) was the diminutive new Chord Qutest DAC ($1795).

Chord Electronics, distributed by Bluebird Music, took pride of place in two systems in their multi-chambered suite on the 35th floor…

Given the dramatic drop in the number of high-end audio exhibits at CES, only two companies chose to occupy the huge, high-ceilinged suites on the Venetian Hotel's 35th floor. The first, Lamm Industries, from the quiet little hamlet of Brooklyn, NY (where John Atkinson also lives), threw caution to the winds with a system whose total retail price was $649,440.

Earlier this year Anthem launched the STR Integrated Amplifier in a return to 2-channel, and representative Devin Zell explained that they have expanded that line this year with a 2-channel preamp and dedicated amplifier. The STR preamp goes for $4,000 and the STR amplifier goes for $6,000 and are available now.

Largish one-box streaming systems have taken off it seems, and I guess we shouldn't be surprised. First the Sonos and inexpensive Bluetooth systems took hold and then inevitably high-end audio saw an opportunity. Naim and Bluesound (among others) come to mind and we can now add Technics to the list.

Michael Fremer over at AnalogPlanet.com will eventually have more, including video, on this beauty, but here are some brief facts for Stereophile readers.
