About the Teres
The Thrax Audio Teres (MK2) is a high-end hybrid power amplifier featuring a single-ended tube input stage with a long-life C3g vacuum tube loaded by a custom phase-splitting transformer, driving two separate single-ended JFET/MOSFET cascode output stages. It delivers tube-like tone, clarity, and second harmonic content with substantial power for inefficient speakers, using zero feedback, solar cell bias for the floating output stage, silicon carbide rectifiers, shunt-regulated power supply for the tube, and microprocessor control. Available in mono and stereo versions, it maintains tonal stability across power levels due to interstage transformer isolation. Launched around 2015-2016, with MK2 updates; currently listed on the manufacturer's site.
