PS Audio Lights Up Tube Amps

Munich, Germany — PS Audio’s first vacuum-tube audio products go on display this week at the Munich High End show.

The Bascom H. King Signature 250 and 300 amplifiers have begun shipping in the U.S. at $7,499 each, marking the highest-priced products ever in the company’s line.

Both amps feature a 6922 dual triode tube front end followed by all-MOSFET circuitry, including the output stage, the company said.

The amps, shown in prototype form at the Rocky Mountain Audio Fest last October, are designed by Bascom H. King, whose 50-year career includes work for Infinity, Conrad-Johnson and Constellation, the company said. The amps are King’s first for PS Audio.

The 250 is a stereo amp rated at 2×250 watts into 8 ohms and 2×400 watts into 4 ohms. The 300 is a monoblock amp rated at 300 watts into 8 ohms and 500 watts into 4 ohms. It features twice the current-capacity of the 250.

“In terms of build quality and sound quality, it is the equal of amps 10 times their price,” a spokesman claimed.

The Munich show, which runs from May 14-17, is open to the trade and public. It will feature almost 270,000 square feet of audio and home-entertainment products from suppliers around the world.
