LATEST ADDITIONS

In the February 2010 issue of Stereophile, I reviewed Bryston's first standalone digital-to-analog converter, the BDA-1 ($1995). Five years later, Bryston released the BDA-2, which replaced the BDA-1's 24-bit/192kHz Crystal CS-4398 DAC with a pair of AKM DAC chips in balanced mode. In a February 2016 Follow-Up (footnote 1) I reported that the BDA-2 deepened and widened the BDA-1's soundstage, among other performance gains.

The last time I reviewed an Audio Research component—it was the VTM200 monoblock amplifier in January 2001—my hair was mostly dark brown. The wait since has been not of my choosing, but that's now flux under the circuit board. Since then, much has happened to both me and to the Audio Research Corporation, a long-lived company for which the descriptor "legendary" is well deserved.

It's Thanksgiving week, which means that if you're in New York City, you can (and should) go see two of the best jazz bands at two of the best jazz clubs. Maria Schneider's Jazz Orchestra is playing at the Jazz Standard through Sunday (except for Thanksgiving Day). Jason Moran's Bandwagon trio is playing at the Village Vanguard through Sunday (including Thanksgiving Day).

This past Friday, November 17, critically acclaimed French audio startup Devialet officially opened the doors to their first US standalone store right here in SoHo, NY. This store joins five other standalones globally (Paris, London, Berlin) and, as of yet, no future plans of additional US locations have been disclosed.

Drummer/composer Dan Weiss has wide-ranging musical tastes, superb skills, and a rocking little Rega-based system in his cozy Brooklyn, New York apartment. Dan has drummed with many jazz greats, but it's his own projects that have generated the greatest interest. He's a thinking musician's musician, one who astutely assesses the pros and cons of every situation. Dan doesn't enter musical projects or hi-fi scenarios lightly. When considering his first major stereo purchase Dan listened to many combinations of turntable/CD player/amplifier/speaker(s).

It has been 20 years since I first became aware of the British company Data Conversion Systems, which manufactures audio products under the dCS brand. Rather than use off-the-shelf conversion chips, the groundbreaking dCS Elgar D/A converter, which I reviewed in our July 1997 issue, featured a then-unique D/A design that they called a Ring DAC. This featured a five-bit, unitary-weighted, discrete DAC running at 64 times the incoming data's sample rate—2.822MHz for 44.1kHz-based data, 3.07MHz for 48kHz-sampled data and its multiples—with upsampling and digital filtering and processing implemented in Field Programmable Gate Arrays (FPGAs). Oversampling to a very high sample rate allows the word length to be reduced without losing resolution, and use of a low-bit multi-bit DAC makes for very high accuracy in the analog voltage levels that describe the signal. (If this seems like voodoo, for a given signal bandwidth, bit depth and sample rate are related. To oversimplify, double the rate, and you can reduce the bit depth by one bit while preserving the overall resolution.)

I'm a progressive who enjoys the company of his conservative friends, a Catholic who's thankful for his atheist friends, and a carnivore who cherishes his vegetarian friends. I'm also a vintage-audio enthusiast who loves his audiophile friends who aren't so inclined—so I was doubly happy to see, in the September 2016 edition of Michael Fremer's "Analog Corner," a hearty endorsement of Ortofon's latest SPU: a 58-year-old phono-cartridge design that, like the coelacanth, continues to thrive despite expectations.

Mikey is a longtime friend who harbors no love for vintage phonography—yet after playing his first record with the new SPU #1E ($659), he wrote: "I immediately, and much to my surprise, got what the SPU cult is all about."
