Camelot Technology Uther v2.0 D/A processor

666uher2c_2.jpgThe apparent demise of Audio Alchemy left a niche in the marketplace for a supplier of innovative, high-value digital components to provide the less-than-wealthy audiophile with state-of-the-art technology. Although Camelot Technology existed before Audio Alchemy went away, they have quickly taken over this niche with some interesting components. And I understand that some of the former AA technical personnel consulted for Camelot in the development of these products. (A recent press release indicates that Genesis Technology also played a major role in their design.)

Camelot Technology Dragon Pro Jitter Reducer

666camdragon.jpgThe Dragon Pro is, I believe, the most eagerly awaited of the Camelot products. Since the disappearance of Audio Alchemy's DTI•Pro 32, no comparable anti-jitter and resolution-enhancement product has come along to replace it. (Yes, there are simpler anti-jitter boxes, and there is the Genesis Digital Lens, but these are not truly comparable in approach.) Well, the Dragon is everything that the DTI•Pro 32 was, and more!

The Dragon Pro anti-jitter box offers both jitter reduction and resolution enhancement, along with I2S in/out. Considering the number of Web newsgroup ads from folks wanting to buy AA DTI•Pro 32s, this baby has a waiting market.

Audio Research DAC1 D/A converter

The past 12 months have seen some remarkable developments in digital playback. Standards of digital musicality are far higher than they were a year ago, both on an absolute performance basis and in terms of what you get at various price levels. No other component category has seen such tremendous gains in value for money or number of new products introduced. It seems hard to believe that since Vol.13 No.6 (12 issues ago), we've reviewed such noteworthy digital processors as the Meridian 203, Proceed PDP 2, Stax DAC-X1t, Theta DSPro Basic, Wadia X-32, Esoteric D-2, PS Audio SuperLink, and VTL D/A. Each of these converters brought a new level of performance to its price point—or, in the case of the Stax and VTL, established a new benchmark of ultimate digital performance.

Just as these units provided stiff competition for previous products, so too will they come under the assault of improving technology. The art of digital processor design is so young that we can continue to expect further improvements coupled with lower prices as designers move up the learning curve.

Musical Fidelity Digilog D/A processor

The rapidly evolving world of the late 20th century is the source of much stress. Changes in the status quo, whether wrought by social, political, or technological forces, are often accompanied by anxiety brought on by the struggle to assimilate new patterns of thought. New ideas necessitate abandoning or modifying one's old ideas, thus creating conflict (footnote 1). However, these periods of rapid change can also be exciting, allowing one to chart a course of discovery and growth.

Bel Canto e.One DAC3.5VB D/A converter

Minnesota pride is a funny thing. As Garrison Keillor points out weekly on A Prairie Home Companion, to be a Minnesotan, the first and crucial step to be taken is that of self-effacement. It is unclear to me whether this is the cause or symptom of Minnesotans ability to endure brutal winters, excel at the creation and consumption of hot dish (which the rest of the God-fearing world knows as casseroles), or their miraculous lineage from generations of Norwegian bachelor farmers. Whatever it is, Minnesotans tend to quietly get their jobs done with little more fanfare than a cup of coffee and a slice of rhubarb pie.

Musical Fidelity M1 DAC

The M1 DAC is by Musical Fidelity. At $699, it's a stunning bargain. Comparing it to $995 for the Digilog in 1989. Meanwhile, the M1 is far more versatile, way better built, and, if memory serves me right, sounds vastly better.

It appears that the way to sell a DAC in 2011 is to almost give it away, in real-dollar terms. Some people pay far more than this for a set of speaker cables, a pair of interconnects, even a power cord. The M1 DAC is a piece of kit that can transform your system. I kid you not.

Arcam Delta Black Box D/A processor

As explained by Ken Kessler elsewhere in this issue, the English A&R Cambridge company made their name by producing one of the UK's most successful integrated amplifiers, the 40Wpc A60. This neatly styled model was in production for a decade or so and was the basis for a large number of good-sounding but inexpensive audio systems. These days, the company, whose products in the US sell under the Arcam banner, is a major British hi-fi manufacturer, with a product line that includes integrated amplifiers, tuners, loudspeakers, cartridges, and even a CD player. A&R was, I believe, the first UK manufacturer to obtain a player-manufacturing license from Philips, and with the product under review here, has broken new territory for a supposedly "audiophile" company in having a custom LSI chip manufactured to their own requirements.

Esoteric D-07 D/A processor

In November 2009, I took part in an intriguing comparison between live and recorded sound. I first recorded a live piano recital in 24-bit/96kHz digital, then allowed the audience to immediately hear the recording in the same room. (See my February 2010 thoughts on the comparison here.) For playback, I used two of the mono Esoteric D-01VU D/A converters locked to the ultra-high-precision Esoteric G-0Rb "atomic" master clock. I was very impressed by the sound of this cost-no-object digital system, so when I visited the Japanese company's room at the 2010 Consumer Electronics Show and saw their new, relatively affordable D-07 D/A processor ($4800), I asked for a review sample.

Chord Chordette Gem D/A processor

There's home cooking on one side of the hedge and fast food on the other, and the world moves farther from the former and nearer to the latter with each passing day. So it goes in domestic audio, where virtually every new milestone of the past quarter-century has pointed far more toward convenience than toward quality.

Depressed? Don't be. Those of us in the perfectionist community have a history of dealing with such things, howsoever slowly and inefficiently. (footnote 1). We're getting better at it, too, year by year. An example: Chord Electronics, of sunny southern England, has now brought to market their Chordette Gem D/A converter ($799) which they offer as an affordable means of getting perfectionist-quality sound from computer-music files.

dCS Debussy D/A processor

Don't have $80,000 to drop on dCS's four-component Scarlatti SACD stack that I reviewed in August 2009, or $17,999 for their Puccini SACD/CD player that John Atkinson raved about in December 2009? Even if you do, the new Debussy D/A processor ($10,999) might be a better fit for your 21st-century audio system. Sure, you don't get an SACD transport—or any kind of disc play, for that matter—but the odds today are that you already have a player you like that's got an S/PDIF output that can feed the Debussy.
