CES 2014

John Atkinson | Jan 19, 2014 | 0 comments

“A kiss back to Sony,” was how Nelson Pass described the debut of a unique pair of Pass Labs monoblocks driving Sony’s SS-AR1 speakers in the Sony room at Venetian. And it was an affectionate kiss indeed—the sound in this room, with a Pass Labs XP-20 preamplifier and Sony’s HA-P1ZES media player, I thought one of the best of the 2014 CES. Yes, it had superb clarity and dynamics, with an impossibly low noisefloor on the 24/176.4k Reference Recordings file of Stravinsky’s Firebird, but these qualities were even apparent on a Red Book file of a Rossini opera excerpt. There was something just right about the sound.

Pass Labs XA60.5 monoblock power amplifier

Solid State Power Amp Reviews Audacious Audio

John Atkinson | Dec 30, 2013 | First Published: Jan 01, 2014 | 13 comments

Whereas the Pass Labs preamplifiers are designed by Wayne Colburn, the power amplifiers are the work of company founder and high-end audio veteran Nelson Pass, who even lays out his own circuit boards. The X-model amplifiers, beginning with the X1000 in 1998, were the first implementation of Nelson Pass's patented Supersymmetry topology (see "Nelson Pass on the Patents of Pass"). The XA series, which debuted in 2002, combined Supersymmetry with the single-ended class-A operation of the Aleph series. The XA.5 models offer detail improvements over the XAs.

Canadian loudspeaker company PSB International celebrated both its 25th anniversary in July and the 10th anniversary of the introduction of its Stratus series. (I review the latest version of the flagship Stratus speaker, the Gold i, elsewhere in this issue.) Started by Paul Barton and two friends in the summer of 1972, PSB Speakers was named after Paul and his high-school sweetheart Sue (now his wife). Paul & Sue Barton Speakers is now part of Lenbrook Industries, which distributes NAD, Marantz, and Bang & Olufsen in Canada, and which in turn is part of the Canadian conglomerate Lenbrook Inc.

"I don't believe it!"

PBN

T.H.E. Show Newport 2013

John Atkinson | Jun 10, 2013 | 3 comments

PBN’s Peter Noerback always gets a good sound at shows and Newport Beach was no exception. The KAS2 speakers ($38,000/pair) might have thought to be too big for the room, but driven by the 200Wpc Olympia-AX amplifiers, bridged for mono operation when they deliver 800W into 8 ohms ($22,000 each), they produced a delicious full-range sound, even one that was a touch too mellow, on Madeleine Peyroux’s rendering of “Bye Bye Love.”

PBN Montana's KAS2 Kicks...

CES 2008

John Atkinson | Jan 12, 2008 | 0 comments

PBN's Peter Noerback had emailed me back in December about his new Montana KAS2 tower. The 300lb, 6'-tall speaker has twin 12" woofers top and bottom powered by a 1kW amplifier, with what appear to be top-of-the line 9" lower and 5" upper midrange units from SEAS flanking a 1.125" tweeter. An active, line-level bass extender, the Olympia EX, pushes the low-frequency extension below the resonance point of the woofers. Sensitivity is specified as a very high 93dB/W/m. The sealed cabinet features a solid-maple front baffle and is an asymmetrical hexagon in shape to minimize internal resonances. Price, considering the enormous size of the speaker, is a relatively realistic $38,000/pair, which includes the bass extender.

PBN's Sammy Speaker

CES 2010

John Atkinson | Jan 14, 2010 | 4 comments

San-Diego-based PBN is best-known for its heroically proportioned loudspeakers, but PBN's Peter Noerbaek introduced his new Sammy loudspeaker at THE Show, which, as you can see from the photo, is a little more manageable in size. The 55"-tall Sammy uses premium Scanspeak drive-units in an unusually constructed cabinet (see next photo): a new, long-travel 10” Revelator woofer, a wide-range, 4” Illuminator midrange unit, and the Danish company's new pressure-formed beryllium-dome tweeter. Price will be $29,500/pair.

PBN's WAS2 Speaker

CES 2012

John Atkinson | Jan 18, 2012 | 4 comments

Robert Deutsch reported below on PBN's $14,999/pair Liberty speaker. My attention in the company's large room at T.,H.E. Show was attracted by the large WAS2 (right), which costs $55,000/pair, with its piano-black lacquer-finished enclosure and mahogany hardwood front baffle, and weighs 1000 lbs/pair. It combines two 15" subwoofers, driven by a 1kW ICE-Power amplifier, two 8" coated paper-cone woofers, two 5.25 Nextel-coated paper-cone midrange units, and a 1.1" soft-dome tweeter. Frequency response is quoted as 18Hz–22kHz ±1.5dB and sensitivity is said to be 94dB!

PBS, Politics, Information, & Tweaks

As We See It

John Atkinson | Nov 29, 2007 | First Published: Jul 01, 1995 | 0 comments

In this month's "Letters," Donald Bisbee raises the subject of the government's proposed reduction in funding for the Corporation for Public Broadcasting (CPB), I agree with Mr. Bisbee that commercial radio broadcasting in the US is an intellectual desert. Music is narrowcast, with listeners' tastes bound into predigested categories. There is no depth or analysis to radio news programs, other than discussions by populist commentators who, no matter what you may think of their politics, usurp the ability of their audiences to think for themselves. As a regular listener to NPR and watcher of PBS, I feel that public broadcasting is an essential factor in American public discourse (footnote 1), but not for the reasons some might think.

PC Audio @ RMAF

RMAF 2009

John Atkinson | Oct 07, 2009 | 5 comments

There was full program of seminars and workshops at RMAF, as well as my own "Squeezing the Music Till the Bits Squeak," the session featuring Harry Pearson, and Michael Fremer on "Turntable Setup," I moderated a panel session, "How to Get the Most Out of Computer-Based Audio," on Saturday afternoon. The A-List panel—(from left to right) Gus Skinas (SACD Center), John Stronczer (Bel Canto Design), J. Gordon Rankin (Wavelength Audio), Charlie Hansen (Ayre Acoustics), record producer Joe Harley, and Chris Connaker (www.computeraudiophile.com)—discussed the best way to use a computer as a legimate source component in a high-end audio system. All concerned felt this was the way forward for the high-end audio industry, particularly with the increasing availability of hi-rez downloads, and it was a shame that the session was limited to an hour.
