MEASUREMENTS

I measured the Balanced Audio Technology VK-56SE using my Audio Precision SYS2722 system (see the January 2008 “As We See It”). The VK56-SE looks identical to the VK-55SE, which Wes Phillips reviewed in April 2010, and it was instructive to compare its measured performance with that of the earlier amplifier.2 Like the VK-55SE, the VK-56SE has four output terminals for each channel, various pairs of which can be used to provide a feed from three different output-transformer taps labeled High, Med, and Low. I performed a complete set of mea surements from each tap, but have concentrated on the Low outputs in this discussion, as those were the taps preferred by Herb Reichert.
