The Bryston BP-25MC preamplifier is a full-function control center with one balanced and four single-ended inputs, including one input for a moving-coil cartridge. The BP-25 is shielded in a black steel cabinet said to reduce electromagnetic interference effects. The power transformer is housed in a small external chassis, the BP-PS. The BP-25's remote control allows volume up/down, along with buttons for mute and absolute polarity. Signal switching and audio connections, including balanced and unbalanced input and output connectors, are heavily gold-plated to provide good long-term connections. A 12V AC/DC screw terminal connector on the rear of the power supply provides convenient use when used in conjunction with the remote start feature optionally available on Bryston power amplifiers.

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.

With high-end audio dealers getting scarcer, audiophiles often turn to the Internet or mail-order for products. Would you buy something you hadn't yet heard?

<I>May the Web be with you:</I> You'd think that forward-thinking tech-savvy companies such as those involved in high-end audio would be among the first to <I>get</I> 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 <A HREF="http://stereophile.com/news/050205red/">Burwen Bobcat</A>, 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.

Another chapter has closed in the saga of the Dorian Group, but the story seems far from over. As we <A HREF="http://www.stereophile.com/news/040405dorian/index.html">reported last month</A>, 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.

MusicGiants says it will be the first company to offer high-fidelity downloads, but it will also <A HREF="http://www.stereophile.com/news/051605musicgiants/">spy on your computer</A> to see what other music files you may have. Are you interested in a service like this?
