Ever since I installed dedicated power lines for my multichannel system, I've been wrestling with the issues of surge protection, power conditioning, and voltage regulation. I start with a bias based on decades of happy listening without being concerned about any of these problems, and my belief that competent electronic components must be, and are, designed to perform in the real world. After all, whether the device's AC power supply is a traditional transformer-bridge-reservoir or a switching supply, its output should be a DC source that is sufficient to let the active circuitry meet its specifications. Many manufacturers, such as Bryston, recommend bypassing any line conditioners and plugging their components directly into the AC outlet.
According to a study published by anesthesiologists Chakib Ayoub, Laudi Rizk, Chadi Yaacoub, Dorothy Gaal, and Zeev Kain at the Yale School of Medicine, music reduces intraoperative sedative requirements in patients who received surgical procedures under anesthesia.
May the Web be with you: You'd think that forward-thinking tech-savvy companies such as those involved in high-end audio would be among the first to get how well the Internet works at spreading the word about their products. In nine cases out of ten, you'd be wrong. Companies introduce new products, upgrade old models, and venture into entirely new technologies without ever changing their websites.
In my report on Red Rose Music's HE2005 debut of the Burwen Bobcat, I complained about the lack of before and after demonstrations of the technology, as well as the difficulty of extracting information about what the product actually did. In the last week, I have received correspondence that sheds light on both cavils.
Jimmy Martin, the self-styled "King of Bluegrass," died at a hospice near his home in Hermitage, TN on May 14. Martin had been diagnosed with bladder cancer in 2003, but the progress of the disease was slow, and the first of two hospice stays was cut short by an apparent recovery. Significantly, Martin never gave up his plans to perform at this year's Bill Monroe Bluegrass Festival in Bean Blossom, IN.
Another chapter has closed in the saga of the Dorian Group, but the story seems far from over. As we reported last month, Dorian had filed for bankruptcy and unsuccessfully attempted to auction its assets. The creditors and former owners of Reference Recordings were also nipping at Dorian's heels to get their label back.
Although Mark Levinson Audio Systems components continue to be produced, the company's headquarters moved in late 2003 from the Madrigal plant in Middletown, Connecticut, to Harman Specialty's facility in Bedford, Massachusetts. There ML shares manufacturing and sales space with Harman's other high-end lines, Revel and Lexicon.
This lapsed fan of electrostatic speakers finds it curious that, while MartinLogan is the predominant representative of this technology in the US, I had never auditioned an ML design in my home. I've enjoyed many Janszen tweeters, a KLH 9, an AcousTech X, Stax ELS-F81s, and I've dallied with Quad ESL-63s. But as dumb luck would have it, the first MartinLogan speaker to reach me, the new Montage, is a hybrid model.
