Nagra's VPA amplification system consists of two slim, handsome monoblock amplifiers intended for vertical placement. They look good adjacent to the speakers. However, two 845 tubes put out a <I>lot</I> of heat, so the amplifier should be at least a foot away from your speakers...unless you're <I>looking</I> for a nice crackle finish.

Last month (click here for previous Fine Tunes) I tipped you on how to check the AC plug orientation for transformer current leakage—the best sound is often found at the lowest voltmeter reading. Roger Skoff of XLO suggests another technique that's worth passing on to you, if only because the imagery is so . . . piquant: Leave the speaker cables hooked up and pull the interconnects from the power amplifier. Turn it on and "stick your head in the speaker," as Roger puts it, checking for the level of hum. (Imagine a pair of bony audiophile legs waving crazily out of the bell of an Avantgarde Acoustics horn speaker.)

Any audiophile who stumbles onto one of the more cantankerous audio newsgroups ("wreck audio opinion," anyone?) may wonder what has happened to the modern breed of audiophiles. One suspects that religious wars pale when compared to how some audio pundits jostle against each other! But over the years, there has <I>always</I> been a wide variety of opinion. For a perspective written decades ago that still holds true today, we present J. Gordon Holt's classic "<A HREF="http://www.stereophile.com//features/104/">Why Hi-Fi Experts Disagree</A>."

Forget about tuning dots, mystical poker chips, and clocks with programmed electrons. They're all hopelessly out of date.

Last week saw a flurry of announcements in the online audio and video streaming business, capped off by <A HREF="http://www.yahoo.com">Yahoo!</A>'s acquisition of <A HREF="http://www.broadcast.com">Broadcast.com</A&gt;. Yahoo! says it has signed a definitive agreement with Broadcast.com whereby Yahoo! will issue 0.7722 of a share of Yahoo! common stock for each share of Broadcast.com common stock. In addition, all outstanding options of Broadcast.com will be converted into Yahoo! options. The acquisition is expected to be completed in the third quarter of 1999 and is valued at around $5.7 billion, including $4.8 billion in Broadcast.com common stock and $900 million in stock options.
