Wilson Audio Specialties considers the Yvette ($25,500/pair) to be the replacement model for the Sophia Series 3. I would argue that the Yvette is an entirely different animal. There are obvious similarities between the Yvette and Sophia. Each is a floorstanding, three-driver, three-way design. Each comprises a single box with a separate internal chamber for each driver. The Sophia's woofer and midrange chambers are ported; the Yvette's are respectively ported and vented. The two models are about the same size and, from the back, look a lot alike.

It would be an understatement to say that in 2001, when Nordost introduced their original Valhalla cables, they were a revelation for me. Their focus and resolution of detail were like nothing I'd ever heard, and revealed in recorded performances a startling energy and realism. Throw in their seemingly absolute transparency, and similarly unique levels of spatial and temporal precision, and the Valhallas established a new standard of sound quality in audio cables. Although their tonal balance was cool, as I reported in my first review of them in the November 2001 issue, they were the only game in town in terms of reproducing the feel of a live performance. I immediately adopted them as a reference cable, and they remain a reference for me today.

A reader once noted that I tend to stick with the same reference gear longer than most reviewers. In addition to Audience's Au24e interconnect, I've been using Nordost's Valhalla, Nirvana's S-X, and Stereovox's SEI-600II for many years. They're ancient in audiophile terms, and, other than the Audience cables, have long since been discontinued or replaced. However, they are still excellent, and conveniently define a continuum of qualities that I use to assess cables. At one end, the Nordost Valhalla is sharply focused and excels at reproducing transients. At the other end, the Nirvana S-X strips away electronic grunge, and beautifully conveys the continuity of the space and musical flow. The Au24e and Stereovox are near the middle and share many—but not all—of the others' strengths.

In the September 2005 issue (Vol.28 No.9), I reviewed Simaudio's first reference-quality power amplifier: the 1000W, 220-lb Moon Rock monoblock ($37,000/pair). At the time, the Rock was a dramatic departure for Simaudio, then primarily known as a maker of midpriced gear that was good for the money. I found a lot to like about the Rock, concluding that while it wasn't quite up to the standard of the best superamps of the time, it was very good—and, for Simaudio, an admirable first shot at the state of the art.
