The Eastern European Connection
Believe it or not, the vacuum tube is not only still with us (television CRTs are a type of vacuum tube), but as a side benefit of the fall of Eastern Europe and The Soviet Union, the traditional vacuum tube is becoming a more common site in Western high-end audio products. With U.S. and Asian companies firmly entrenched in production of digital solid state devices, countries that had previously been behind the digital curve such as Russia, Eastern Europe, and even China still have large tube manufacturing facilities and thus, have been producing and exporting vacuum tubes to the West more freely in the last decade or so. As a result, the high end audio market has tapped into this phenomenon like gangbusters.
Vacuum Tube HiFi Components
Many "true" audiophiles have never been completely satisfied with the sound quality and performance of transistors and integrated circuits, therefore, a niche market has opened up for vacuum tube audio equipment. Manufacturers, such as Audio Research, Cary Audio, ECP Audio, Granite Audio, Manley Labs, McIntosh, Rogue Audio, and others are also quenching the thirst for vacuum tube products with their exceptional lineup of home audio equipment.
In fact, even the iPod hasn't escaped the vacuum tube treatment as there are now an ever-growing assortment of iPod vacuum tube audio systems
Home Theater Applications
The Vacuum Tube has also made its way into the home theater environment, with products, such as: The Jolida Vacuum Tube CD Player, and the Rockford Fosgate FAP-V1 5.1 Channel/Dolby Pro-Logic II Preamp. Add a multi-channel hybrid vacuum tube power amplifier, such as the Butler Audio Model 5150, and you can have a vacuum tube based home theater audio system.
Vacuum tube audio for home theater hasn't gone unnoticed by big player Samsung, who has introduced a line of vacuum products, including an Audio Dock and two Home Theater-in-a-Box Systems.
Vacuum Tubes In Your Ear and On The Road
In addition to home audio and home theater vacuum tube-based products, other innovative applications for vacuum tubes in audio also include the Apex Audio and Vincent Audio Vacuum Tube Headphone Amplifiers. Also, for those who can't leave their vacuum tubes at home, companies such as Butler Audio (Tube Driver) and Milbert Amplifiers produce a line of unique vacuum tube car audio products.

The Vacuum Tube Lives On
Even with all the emphasis on digital technology in the new century, the vacuum tube is making a big comeback with audio aficionados (or did it really ever leave?). Some say that the warm, glowing sound of a good vacuum tube amplifier has no equal.
I still have fond memories (early 70's) of owning a Dynaco Stereo-70 tube power-amp which, today, is considered a true "classic" in home audio technology. Its design changed through the years and was discontinued for a time, but has now been revived with a new design, at a much higher price than I would have paid in my college years. Check out a review of the Dynaco Stereo-70 by Stereophile Magazine .
Supported by continuing loyalty from the audiophile community and audiophile press, in addition to increased profits for Russian, Eastern European, and Chinese suppliers, the vacuum tube's continued success might just be insured, despite the digital revolution.
