LATEST ADDITIONS

Some contentious issues will not be resolved in my lifetime: vinyl vs digital, tubes vs solid state, subjective vs objective, streaming vs physical media.

Also, subwoofers vs no subwoofers in a stereo music system.

Hi-fi system resolution has long been the cause of heated arguments. But when it comes to converting digital data to an analog signal, there can be no argument. Data go in at one end of a DAC and an analog signal comes out of the other end, with a noise floor directly rated to the combination of the converter's digital and analog resolution. Ever since I started measuring digital products for Stereophile, I have been expressing a D/A processor's effective resolution in terms of the equivalent number of bits.

I consider Charles Mingus one of the great American composers, at least on par with the most celebrated American classical dudes. With apologies to fans of that music, I'd much rather listen to this record, or any of several other Mingus recordings, than, say, Billy the Kid or Rhapsody in Blue. What makes Mingus great is precisely that, in contrast to Copland and Gershwin, when he explored the vernacular, it wasn't some pale imitation.

For the first time in the two years I've been living in this apartment building, I've received a noise complaint from a neighbor. Coincidence?

As it happened, yes it was a coincidence. True, my music was pretty loud, and the bass from the Piega Premium Wireless 701 loudspeaker system ($7495/pair) was anything but reticent, especially considering the tower's sleek appearance. But I was not the source of the specific noise that caused the complaint. That was the sloppy bass from another neighbor's inferior sound system. (The bass from this Piega system isn't sloppy.)

Nothing about Alice Phoebe Lou's musical career reflects industry norms. She maintains complete control over every aspect of her work, from creation to release. The result is always original and fascinating. Lou is at her best when she has an audience to connect with; this live performance is an ideal introduction to her powerful voice and courageous message.

After completing a PhD in electrical engineering at Imperial College London, Floyd E. Toole joined Canada's National Research Council (NRC), where he would stay for more than 26 years doing audio-related research. He continued his research at Harman International after leaving the NRC in 1991. When Toole left Harman in 2007 (footnote 1), Harman kept the work up under NRC alum Sean Olive—which fact surely has much to do with the excellence of their current loudspeaker lineup.

The two biggest sonic jolts I've experienced involving phono preamps were from two very different ones: the Petr Mares's Connoisseur 2.0 and Boulder's 2008, which was reviewed in the July 2002 Stereophile. The first was hand-built, single-ended, housed in a wooden case, limited to 100 units, and, when I got to hear it in the mid-1990s, cost around $6000, or about $10,000 in today's dollars. The other was a feature-laden, double-chassis monument to flexibility and surface-mount high technology. It featured beautifully finished, flush-mounted mirrored buttons your fingers just wanted to press.
