With Trachea, the latest superb recording from Norwegian label 2L [http://www.2l.no], label founder and recording engineer Morten Lindberg continues his commitment to contemporary music. Here, working with Schola Cantorum, Norway’s well-tuned 55-year old chamber choir, under the leadership of Tone Bianca Sparre Dahl, Lindberg scores big with six fascinating and musically accessible choral compositions, all but one of which were written in the last five years.

Louisiana-born, 58-year-old saxophonist Branford Marsalis has achieved singular status in the worlds of both jazz and classical music. He cut his teeth playing hard-hitting hard bop with Art Blakey's Jazz Messengers, led The Tonight Show band, and kicked it with the Grateful Dead. He's toured and recorded with Sting, costarred in the Spike Lee film School Daze (1988), and made his classical debut with the New York Philharmonic performing Glazunov's Concerto for Alto Saxophone on Central Park's Great Lawn.

British digital-audio specialists dCS (Data Conversion Systems) has been on a roll. Since the September 2015 introduction of the Rossini DAC ($23,999), the single-box Rossini Player ($28,499), and the Rossini Clock ($7499), they've released a number of new products and software/firmware updates. In 2016 came network firmware updates that established dCS DACs and Players as Roon endpoints. 2017 brought improved (v1.05) software for the Rossini DAC and Player, and 2018 an update to process MQA, followed by the October 2018 introduction of the Rossini upsampling SACD Transport ($23,500—see John Atkinson's review in the May 2019 Stereophile). Then, in January 2019, dCS released their Rossini v2.0 software, which applies to both the Rossini DAC and the Rossini Player, and which is offered free to Rossini owners.

I had never been alone with a Russian-manufactured 6C33C tube. At least not at night, in the dark. The first night Balanced Audio Technology's VK-56SE tubed amplifier was in my system, I sat on the floor studying the unusual shape and dark orange glow of its four 6C33C-B output tubes. I noticed their brightly lit, cathedral-like innards. My Russian neighbor told me they were used as regulator tubes in MiG jets during the Cold War. I could believe it—their exposed cathodes were the exact color of the Soviet flag. From more than a foot away, I could feel the heat from their high-amperage filaments.
