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."

There's a lot happening, in Raleigh and Charlotte (featuring Michael Fremer's Turntable Set-Up seminar), and in Edmonton, Calgary, and Ontario.
