Ypsilon's Demetrius Baklavas (right in photo) and Ypsilon's US distributor, Brian Ackerman of AAImports, demonstrated the Aelius amplifier to John Atkinson (left) and myself—the amplifiers were doing a fine job of producing dynamics and superb open highs from the plasma tweeters of the new, floorstanding Lansche 7 loudspeakers.

Audio Research's Chris Ossanna proudly shows off the company's new $25,000/pair, two-chassis Reference 250 monoblocks, which employ the new KT-120 output tube. This amplifier has 50% more power-supply capacitance than their previous flagship, the Reference Anniversary 110, and uses the same type of Teflon coupling capacitors they sourced for their Reference Anniversary preamplifier. The front panel metering allows the consumer to check the bias and to adjust the speed of their response to either fast or slow.

JL Audio's home high-end audio subwoofer engineer, Brett Hanes, proudly shows off the company's new $1700 ES-112 subwoofer (wood finish) that uses clever engineering principles to coax better performance and value from a less-expensive product. The ES-112's woofer features the company's only dual-spider driver construction, a smaller voice-coil, though the cone is designed for the same 3" peak–peak excursions found in the company's flagship f212 and Gotham models. Other construction simplifications—you change line input voltage by changing fuses in external fuse holder—make the product more adaptable for international sales. It also has a high-pass output with variable frequency crossover, which will be appreciated by those of us using subwoofers in a two-channel home audio system.

I should begin this review by confessing that I've never been a fan of subwoofers. Most subwoofer systems I've heard have been plagued by a familiar litany of sonic horrors: poor integration between subwoofer and main speakers, boom, bloat, tubbiness, slowness, excessive LF output, and an overall presentation that constantly reminds the listener he is hearing a big cone moving. To me, subwoofers often sound detached from the music, providing an accompanying thump that bears little relationship to the sound from the main speakers. Rather than revealing the music's harmonic underpinnings, subwoofers often obscure them in a thick morass of featureless boom. In addition, adding a subwoofer often destroys the qualities of the main speakers that made you buy them in the first place—just to name a few of my observations (footnote 1).

Other than that, I like subwoofers.

The Random House Dictionary of the English Language defines "myriad," derived from a Greek word meaning "ten thousand," as "a very great number of persons or things." British and unabashedly ambitious, Myryad Systems has set itself myriad design goals for its M-series stereo components: audiophile performance, real-world pricing, convenience, circuit simplicity, common remote-control function, and physical beauty.

"Larry, you have too many amplifiers!" exclaimed John Atkinson during a recent visit. This surprised me—I didn't think it was possible to have too many amps. While I'm not going to open an amp museum, I do have a starter collection of Mark Levinson amplifiers from different eras. This either makes me exactly the right or the wrong person to size up Mark Levinson's new No.532H.

James Tanner, VP of marketing at Bryston Ltd., was frustrated. He'd borrowed a Music Vault 4000 music server to play high-resolution digital music files at Bryston's exhibit at the 2009 Consumer Electronics Show. Most of the time, the server delivered some of the best sound at that event. The rest of the time, there were dropouts and crashes. Tanner later experienced similar dropouts and crashes when he streamed hi-rez digital files over his home network to a Bryston BDA-1 digital-to-analog converter (see my review in the February 2010 issue).

I found a more relaxed Tanner at the 2010 CES. This time, he'd borrowed an Auraliti L-1000 digital file server ($3000 at www.auraliti.com), a box with no front-panel controls, no display, no hard drive, no fans, and no CD drive. Instead of a Windows operating system, the L-1000 ran a stripped-down version of the Linux open-source operating system. Its simplicity of design solved the reliability problems Tanner had encountered the year before.

Then and there, Tanner decided to ask Auraliti to help Bryston create a simple digital music file player. The result is the BDP-1.

James Bongiorno, the engineer behind the Sumo Andromeda, has enjoyed a long and colorful career as an audio amplifier designer. He has cast himself at times as an enfant terrible, exploding at audio critics and running scandalous advertisements (footnote 1). His best-known amplifier is the Ampzilla, produced by Great American Sound, but he also designed the Dyna 400. Currently Jim is living on a boat and serving as part-time consultant to the Sumo Company.
