As a card-carrying member of the Audio Engineering Society and an avid audiophile, I was particularly disturbed by the ideas expressed at the 1990 AES Conference entitled "The Sound of Audio." (A report on the papers presented appears in this month's "Industry Update" column.) The tone of the three-day session in May was set during the Conference Chairman's opening remarks. He said that an AES conference on the sound of audio was "unusual" and "out of the mainstream." Further, he expressed a common underlying attitude among the AES that "audiophile claims" (of musical differences between components) have been "nagging us" and are "an annoyance."

The promise of "perfect sound forever," successfully foisted on an unwitting public by the Compact Disc's promoters, at first seemed to put an end to the audiophile's inexorable need to tweak a playback system's front end at the point of information retrieval. Several factors contributed to the demise of tweaking during the period when CD players began replacing turntables as the primary front-end signal source. First, the binary nature (ones and zeros) of digital audio would apparently preclude variations in playback sound quality due to imperfections in the recording medium. Second, if CD's sound was indeed "perfect," how could digital tweaking improve on perfection? Finally, CD players and discs presented an enigma to audiophiles accustomed to the more easily understood concept of a stylus wiggling in a phonograph groove. These conditions created a climate in which it was assumed that nothing in the optical and mechanical systems of a CD player could affect digital playback's musicality.

The end of two audiophiles' friendship:

666proceedcd12.jpgThe Proceed CD player is the first digital product from Madrigal Audio Laboratories, a company known for their Mark Levinson preamplifiers and power amplifiers, including the very highly regarded No.20.5 power amplifiers. Given Madrigal's track record of producing ultra–high-end (and expensive) components, I was surprised and encouraged that the Proceed CD player is so affordably priced.

The Proceed was a long time in development, reflecting Madrigal's care and thoroughness before releasing a new product. Many technical innovations have been incorporated into the Proceed, and the machine's unusual appearance exemplifies the "start from scratch" attitude behind its development. With its nearly square proportions, grey cabinet, and sparse front-panel controls, the Proceed may set a new trend in audio component styling.

The name Muse Electronics is probably unfamiliar to most audiophiles, requiring some background on the company. Muse is the hi-fi offshoot of a company called Sound Code Systems, a manufacturer of professional sound-reinforcement speaker cabinets and power amplifiers. Founded in 1980, SCS enjoyed some success with its line of MOSFET professional power amplifiers. In 1988, SCS's Michael Goddard and Kevin Halverson, both audiophiles and tube aficionados, redesigned their amplifier for the high-end hi-fi market.

The results are the Model One Hundred (a 100Wpc stereo power amplifier) and the Model One Hundred Fifty ($1900/pair), the 125W monoblock reviewed here. According to Michael Goddard, the primary design goal was to achieve a tube sound with the reliability and ruggedness of transistors. MartinLogan CLS speakers were used extensively during the design/listen/design cycle. As a result of their listening auditions and redesign, many of the changes have now been incorporated into their professional products.

The VTL 225W DeLuxe monoblocks are very similar to the 300W monoblocks that received such an enthusiastic reception from J. Gordon Holt a year or so ago (in Vol.11 No.10) and, ultimately, most of the audiophile community. Technically, they differ only in output tubes and transformer: the 225W uses EL34s, the 300W uses 6550s. The 225Ws, at $4200/pair, cost $700 less than their more powerful brothers. The question may be raised: Why have two models so close in price and performance? According to David Manley, the 225Ws were built on special order for audiophiles who preferred the sound of EL34s to the 300Ws' 6550s. Demand was so great for the EL34 version that he decided to add it to the line. They look almost identical, the only difference being the smaller output transformer on the 225W and an additional filter capacitor on the 300W's top chassis.

The acoustic environment for music reproduction is easily the most overlooked source of sonic degradation. Many fine playback systems are compromised by room-induced anomalies that severely color the reproduced sound. When we live in a world of directional wire, high-end AC power cords, and $4000 CD transports, paying attention to the listening room's contribution to the musical experience takes on greater urgency.

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.

Doug Sax is undoubtedly one of the most controversial and outspoken figures in audio. As co-founder, with Lincoln Mayorga, of Sheffield Lab, Doug pioneered the first modern direct-to-disc recording. His perfectionist methods may be controversial, but the results certainly are not: Sheffield Lab recordings are nearly universally praised by the audiophile community, while the Billboard Hot 100 always features at least one Sax-cut disc.

The Arcam Delta 170 is one of the first examples of an entirely new product category: CD transports. The concept of different CD transports having different sonic qualities is vexing. It is a simple matter to prove that the bit stream contains identical data from virtually any CD transport (see "Industry Update," Vol.12 No.8). According to Arcam, development of the Delta 170 was spurred by audible differences among transports heard by dealers, customers, and Arcam staff. The possibility that CD transports have their own sonic signatures is intriguing.
