LATEST ADDITIONS

Analog Corner #299: Haniwa HCVC01, CAD Ground Control, DS Audio Vinyl Ionizer-001

Lately, current amplification–based moving-coil phono preamplifiers have gotten a great deal of well-deserved press. For years, Haniwa's Dr. Kubo has been designing and selling super–low-internal-impedance cartridges because such cartridges work best with such devices. He has also been designing and selling his own current-amplification phono preamplifier.

Humidity, Concert Hall Sound & Spectral Tilt

I want to talk about the acoustics of live music and recordings. As I write this I'm back in Boston for a week, re-calibrating my ears with (excuse the expression) the "absolute sound" of live music in various concert halls. On Friday the Boston Symphony played symphonies by Mozart and Shostakovich, producing (as always) magnificent sound with the aid of Symphony Hall's near-legendary acoustics.

Gold Note DS-10 D/A processor

I felt like I'd just been offered a choice of 31 flavors of Baskin-Robbins ice cream topped with up to 57 varieties of Heinz ketchup, 57 condiments, and 47 brands of coddled cream. My head began to spin, my stomach churned, and my mouth grew very dry as I read that Gold Note's DS-10 ($2995) was a "chameleon DAC" with 192 setup options that enable it to "completely blend in with different music genres, giving the listener the opportunity to adapt the behavior of the unit to the music playing, to one's stereo system and, most of all, to the listener's taste."

Terry Riley: Get What You Need

For two months, I'd been planning to attend Terry Riley's appearance at Seattle's 536-seat Illsley Ball Nordstrom Recital Hall. For two weeks, I'd been planning to watch a presidential-candidate debate on television. Only one problem: As it turned out, the two events were scheduled for the same night. Even after a decade of trying to master the muddle known as multitasking, it was impossible to do both.

Weiss Engineering DAC502 D/A processor

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.

Revinylization #8: Charles Mingus: Mingus Ah Um

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.

Piega Premium Wireless 701 wireless loudspeaker system

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.)
