New Music: Suun’s “Bambi” & “Red Song”

I’ve been enjoying “Bambi” and “Red Song,” two new pulsing, angular, seductive tracks from Montreal’s Suuns.

Suuns - Bambi b/w Red Song by DOJAGSC

The band explains:

With a couple weeks off this summer in Montreal, we thought we’d take a crack at a few new songs. Stark and futuristic, these are extended jams that may or may not materialize as condensed versions of themselves on records to come. Open air textures, repetition and exploration were the name of the game for us on this one, and the finished product is a refined mining of the ideas that came out. “…

2011 Rocky Mountain Audio Fest: Bigger Than Ever

The 2011 Rocky Mountain Audio Fest, which runs October 14–16 at the Denver Marriott Tech Center, promises more exhibits than ever before. With 480 exhibitors spread over 176 hotel rooms and three vendor areas, and advance attendance figures indicating at least 3500 attendees, the show continues to attract even more of the industry and public despite the economic slowdown. While the proportion of East and West Coast attendees remains stable, you'll see more international attendees, including folks from Thailand, India, Japan, Australia, Argentina, Singapore, Brazil, Canada, Finland, New…

Sandro Perri’s <i>Impossible Spaces</i>

On the surface, Sandro Perri’s Impossible Spaces is an ordinary pop album: We hear pleasant guitar, intelligent percussion, and a voice that, while lovely, is easily appreciated, palatable, unchallenging. But there’s a depth and darkness to this music that begs to be uncovered.

It’s the sweetness of the voice and the liquid tone of the guitar that draw me in, but the subtle shifts in key, the clever instrumentation, the aching cello and odd flute, the broken lines and strangely abbreviated melodies that make me listen again, confuse and enchant, charm and intoxicate.

Wavelength Audio Proton USB D/A converter

I don't remember where I was when the Berlin Wall came down, and I already don't remember what I was doing when Liz Taylor died. (I suppose I was busy not thinking about Liz Taylor.) But I do remember when USB-based computer audio became a serious medium: That was when Gordon Rankin, of Wavelength Audio, introduced asynchronous data streaming, with his proprietary Streamlength software. After that, things picked up speed.

Without asynchronous streaming, USB audio functions in adaptive mode: the computer establishes the data-transfer clock, forcing any outboard digital-to-analog converter…

I set the review sample on a light, sturdy pinewood table of my own construction, never more than 1.5m from my computer, never with interconnects shorter than 5m. Although its front panel looked nice enough, I tended to orient the Proton in such a way that its rear panel—and the LEDs thereon—were in easy view. Playback software was Stephen Booth's Decibel (v1.0.2) on an Apple iMac G5 (OS 10.6.7), playing a selection of AIFF and WAV files of resolutions up to 24-bit/176.4kHz.

During use, the Proton's sample-rate indicators were consistent in correctly signaling the sample-rate families…

Wavelength Audio Proton USB D/A converter Measurements

Sidebar 3: Measurements

I used Stereophile's loan sample of the top-of-the-line Audio Precision SYS2722 system to perform the measurements on the Wavelength Proton (see www.ap.com and the January 2008 "As We See It"); for some tests, I also used my vintage Audio Precision System One Dual Domain and the Miller Audio Research Jitter Analyzer. Source for the test files was my MacBook, fitted with 4GB of RAM and running Mac OS10.6.8 and Pure Music V1.8.

Wavelength warns that the Proton's line-level output will clip with full-scale signals, and advises owners to set the Proton's…

Vivid Audio B1 loudspeaker

When John Marks wrote about the Vivid B1 in his column, "The Fifth Element," in February 2011, he was so excited about the sound he was getting that he asked me to drive up to Rhode Island to give a listen for myself. Not only was I impressed by what I heard at John's, I decided to do a full review of the speaker.

I first heard the B1 ($14,990/pair), Vivid's first product, when it was demmed at the 2004 London Heathrow show, but it didn't reach the US until the 2006 Consumer Electronics Show. The B1 is made in South Africa and engineered by ex-B&W designer Laurence "Dic" Dickie, who…

It seems odd to use the word "generous" to describe the B1's low frequencies, given its fairly small footprint and small-diameter woofers. But generous those lows were indeed. The bass guitar on the "Channel Identification" and "Channel Phasing" tracks on my Editor's Choice CD (Stereophile STPH016-2) had excellent weight, and the speakers had superb articulation with this signal, which can often sound soggy with reflex designs. Jerome Harris's solo bass-guitar introduction to Duke Ellington's "The Mooche," from the Jerome Harris Quintet's Rendezvous (CD, Stereophile STPH013-2), sounded even,…
