About the REX II
The Balanced Audio Technology REX II power amplifier is a high-current, fully balanced, zero-feedback, all-triode design that represents nearly two decades of research into ultimate vacuum-tube amplification. It delivers 80 watts per channel in stereo or 160 watts per channel in monoblock configuration, using 6C33C-B triode output tubes known for their high current delivery and ability to drive low impedance loads comfortably. The amplifier features a fully symmetrical circuit topology, effectively combining two single-ended amplifiers per channel with waveforms summed at the output transformer, eliminating direct current flow through the transformer to reduce low frequency distortion and extend bandwidth. It includes intelligent auto-biasing and electronic protection circuits for ease of use and reliability. The REX II is praised for its combination of high power output, beautiful midrange texture, and excellent frequency extension, making it a modern, uncompromising vacuum tube amplifier.
