Music in the Round #36

Kalman Rubinson May 29, 2009

The first time I ever heard stereo sound, it was in a shop on Manhattan's Radio Row. In addition to the Studer staggered-head tape deck, the system consisted of pairs of McIntosh C8 preamps, MC60 power amps, and monster Bozak B-310 speakers. I can still picture the room and almost hear the sound. I was then an impecunious high-schooler, and while I always strived to buy the best equipment I could afford, I unfortunately was never able to own any of these iconic products. However, when I saw McIntosh's new MC303 three-channel power amp glowing brightly on silent display at the 2008 CEDIA Expo, a light bulb went on over my head: I'd been assessing a series of three-channel and monoblock amps, and the MC303 would fit nicely into my New York City system.

Cambridge Audio Azur DacMagic D/A converter

Sam Tellig May 29, 2009

In 1989, Cambridge Audio, then run by Stan Curtiswho is still active in hi-fi introduced their DAC 1. At about the same time, within a few weeks of each other, Arcam introduced their Delta Black Box and Musical Fidelity their Digilog. I forget who was first among the three. Arcam, I think. But the DAC race was on, led by the British. (There was even a DAC called the Dacula.) US companies got into the DAC race, tooat higher prices, of course.

Jazz at the Chocolate Factory

Fred Kaplan May 28, 2009

I’ve just found out about a new, and unlikely, place to go hear jazz in New York City: the Cacao Bar at the Chocolate Factory, a.k.a. MarieBelle. Most of the time, it’s a chi-chi caf—on the 2nd floor of 762 Madison Avenue, between E. 65th and 66th Streets—that serves hyper-rich chocolates, exotic drinks, and (so I’m told) killer short ribs. But on Wednesday nights, from 7:30 to 10, jazz musicians—a pianist and usually just one or two others (there’s no room for more)—come in and play.

Jay Bennett

Robert Baird May 27, 2009

Sad to hear of the death of guitarist/keyboard player/singer/songwriter/mad genius Jay Bennett at age 45. I don’t want to be a hater here but like many others, his portrayal in the Wilco film, I Am Trying To Break Your Hearthas always been very problematic for me.

Simaudio Moon Evolution W-7 power amplifier

John Atkinson May 26, 2009

When I <A HREF="http://www.stereophile.com/solidpreamps/simaudio_moon_evolution_p-7_lin…; the Moon Evolution P-7 preamplifier ($6900) from Canadian manufacturer Simaudio in March 2009, I was impressed by the qualities of both the audio engineering and the sound. It was a no-brainer, therefore, to follow that report with a review of the matching power amplifier, the Moon Evolution W-7. In March 2006 Kalman Rubinson <A HREF="http://www.stereophile.com/solidpoweramps/306sim">reviewed</A> Simaudio's Moon Evolution W-8, which offered at least 250Wpc into 8 ohms (I measured 310Wpc at clipping). The W-7 looks identical to the W-8, but is 10 lbs lighter, offers 150Wpc into 8 ohms, and retails for $8900 compared with the W-8's $13,500.

Pass Labs XA30.5 power amplifier

Brian Damkroger May 26, 2009

Over the course of his 30-plus years in high-end audio, Nelson Pass's designs have never been far from the leading edge. In his first Threshold amplifiers he pioneered the use of dynamically adjusting bias and cascode circuitry; then, in the later Stasis models, he switched gears to the simpler approach of pure class-A. All were innovative designs, and among the very best-sounding amps of their time, but were just warmups for what was to come. In 1991, Pass Labs introduced the Aleph 0, a class-A amplifier that was a startling departure from conventional solid-state designs and combined design elements generally thought mutually exclusive: transistors, single-ended operation, and the ability to output 75Wpc into an 8-ohm load. Not surprisingly, the Aleph 0 sounded like nothing else, and became the basis for the widely acclaimed series of Pass Labs amplifiers that evolved over the next decade.
