Balanced Audio Technology VK-55 se

The fully balanced, all-triode VK-55SE power amplifier retains all the strengths that make the VK-55 a stellar performer - including the world-class automatic-bias circuit found in BAT's reference REX II Power amplifier--while incorporating the 6H30 SuperTube into a completely revised first gain stage. This is the same tube used in BAT’s REX II models, and provides the VK-55SE with a more transparent, involving reproduction of the musical event. The VK-55SE also employs the same paper-in-oil capacitors used in BAT’s flagship amplifier designs, resulting in more natural and coherent sonics. Finally, the power-supply energy storage is increased to over five times that of the VK-55! 

The Balanced Audio Technology VK-55SE vacuum-tube power amplifier is yet another outstanding addition to our highly-regarded Special Edition series of products.  The VK-55SE retains all of the strengths that have made the VK-55 such a stellar performer - including the same world-class automatic-bias circuit found in our reference REX II Power amplifier, while maintaining the compact form factor that has made this design such a powerhouse in the industry.  So how did Balanced Audio Technology improve upon an already superb, fully balanced, automatic-biasing, all-triode design?
