"Herb is one of those triode-horn guys."
Wrong. Most of my life, I've favored solid-state integrated amplifiers driving small, British-made speakers.
"I'm sure he hates digital."
Wrong again. I sold all my LPs some 12 years ago, and since then I've been filling my days with CDs and high-resolution downloads. (However, I am starting to collect vinyl again, because my vintage DNA still remembers how to worship at the Altar of Black Discs.)

With the Falcon Acoustics LS3/5a
The Line Magnetic LM-518IA mated especially well with the Falcon LS3/5a that I reviewed in August. The amp's 16-ohm taps loved the 15-ohm Falcons, and the Falcons really let those 845 tubes strut their stuff: The bright emitters wrung every last…

The most important thing you can do with a thermionic valve is to hold it in your hand and study it with your eyes. More than you might think, what you see is what you get. High-energy electrons are boiled off the heater or cathode, pass through the wire control grid, and collide forcefully with that big black, gray, or silver thing—the anode, or "plate"—that occupies most of the space inside the bottle. What that anode structure looks like is probably what your midrange will sound like—ie, if the anode looks smooth and big and richly textured, those same…

I measured the Line Magnetic LM-518IA using my Audio Precision SYS2722 system (see www.ap.com, and the January 2008 "As We See It"). Before starting the testing, I followed the instructions in the manual and left the amplifier turned on for 15 minutes; then, without any signal, I adjusted the bias of each 845 output tube to the correct value. (Very little adjustment was necessary.) Next, I short-circuited the inputs and, with the volume control at its maximum, adjusted the hum-balancer potentiometers to give the lowest measured noise for each channel. I performed…
RMAF certainly qualifies as the most friendly and community-oriented show in the US and, perhaps, the world. What other audio show has a Saturday "spouse outing" complete with van and driver; T-shirts for sale, whose proceeds…
