Now Hear This (NHT) was founded to produce low-cost loudspeakers a breed apart from the mass-market variety often found at the lower price points. Co-founder Ken Kantor has a long history in the hi-fi business as a designer at Acoustic Research, NAD, and as a design consultant to some large Japanese manufacturers. NHT's line ranges from the $180/pair Model Zero to the $1200 Model 100.

At $480/pair, the Model 1.3 is midway in NHT's product line. Finished in a gloss-black high-pressure laminate, the 1.3 is elegant, even beautiful, and is distinguished by its unusual angled front baffle. This design means that the rear baffle is nonparallel to the driver, thus reducing the amount of internal cabinet energy reflected back toward the woofer. This is said to improve imaging and midrange purity by reducing comb filtering. In addition, the angled baffle puts the listener directly on-axis with the loudspeakers pointing straight ahead. This increases the ratio of direct-to-reflected sound reaching the listener and further improves imaging.

The Tannoy E11 ($349/pair) is the company's least-expensive model in a wide range of consumer loudspeakers. Tannoy is most often known for its professional models, especially their nearfield, dual-concentric monitors that have become de rigueur on the top of recording consoles. The E11 is a two-way, ported design with a 6.5" woofer and 1" dome tweeter. Both drivers are manufactured by Tannoy, instead of being sourced from a driver manufacturer. The woofer is made from a polyolefin co-polymer, a plastic material with high rigidity and good self-damping properties. To improve power handling and increase sensitivity, the voice-coil is edge-wound on a Kapton former. The surround appears to be made of butyl rubber.

It's easy for reviewers to become jaded by the high prices of some audio products. We get the products in our listening rooms—albeit temporarily—without having to part with our own money. Consequently, we get enthusiastic about products that offer real breakthroughs without, perhaps, fully considering their cost.

Arnie Nudell is one of a handful of designers who could justifiably be called founding members of the high-end audio industry. With Cary Christie, and John Ulrick, Arnie co-founded Infinity in his garage in 1968 and recently joined forces with Paul McGowan, the co-founder of PS Audio, to create Genesis Technologies, the Colorado-based company formed to build ultra–high-end loudspeaker systems.

I visited the Genesis factory in September 1994 and spent some time with Arnie and Paul discussing loudspeaker and amplifier design, and high-quality music reproduction. I asked Arnie how he became involved in high-end audio.

666wawaWadia2000.1250.jpgDuring my reviews of digital processors in the past year or so, I've made comparisons with the Wadia 2000 Digital Decoding Computer first reviewed by Arnis Balgalvis in Vol.13 No.1. I've felt that, as good as the 2000 is, other processors—many costing less than the 2000's $8500 price tag—are now superior.

However, a visiting Wadia representative looked inside our sample and used the word "ancient" to describe its circuitry in relation to current production. In addition, I was never able to audition the 2000 with a glass fiber-optical interface, standard equipment on Wadia's transports. Similarly, the $2000 Wadia X-32 had undergone a minor circuit revision, including the inclusion of the glass optical input. Consequently, a follow-up of these two excellent processors seemed in order.

In hindsight, it was inevitable that two sophisticated digital audio technologies—software-based digital filters and Bitstream D/A converters—were destined to be married in one product. The software-based D/A converters offered by Krell, Wadia, and Theta all used multi-bit ladder DACs, and Bitstream-based units have previously relied on off-the-shelf digital filters.

"In the fields of observation, chance favors only the mind that is prepared."

When Louis Pasteur uttered these words more than a hundred years ago, he must have speculated that they would apply equally well to future circumstances as to the events of his day. What he couldn't anticipate, however, was the technology to which his insight now seems so appropriate.

No, the $399 price listed in the specification block isn't a misprint. And yes, the Audio Alchemy Digital Decoding Engine v1.0 is indeed a full-function outboard digital processor. And since this is the August issue, not April, you can stop worrying that this review is some kind of joke.

The $399 Digital Decoding Engine is for real.

Since the first digital processor on the market using UltraAnalog DACs appeared (the $12,000 Stax DAC-X1t, reviewed in August 1990, Vol.13 No.8), there has been a proliferation of good-sounding processors using this extraordinary—and expensive—part. Among these are the Audio Research DAC1, Audio Research DAC1-20, VTL Reference D/A, and the groundbreaking Mark Levinson No.30 reviewed last month.

Editor's Introduction: In 2013, lossy compression is everywhere—without lossy codecs like MP3, Dolby Digital, DTS, A2DP, AAC, apt-X, and Ogg Vorbis, there would be no Web audio services like Spotify or Pandora, no multichannel soundtracks on DVD, no Bluetooth audio, no DAB and HDradio, no Sirius/XM, and no iTunes, to quote the commercial successes and no Napster, MiniDisc, or DCC, to quote the failures. Despite their potential for damage to the music, the convenience and sometimes drastic reduction in audio file size have made lossy codecs ubiquitous in the 21st century. Stereophile covered the development of lossy compression; following is an article from more than two decades ago warning of the sonic dangers.—Editor
