Stunning high end stereo power amplifier that combines solid-state control and speed with tube tone. Impeccable build quality and an exquisite aluminum finish. 

The Teres uses a single-ended tube input stage loaded with a phase splitting transformer. The transformer then feeds two separate out of phase single-ended amplifiers for output. The tube handles all the voltage gain needed giving the overall sonic character with high content of second harmonic. It is based on the Dionysos gain stage using a new generation of our choke-rectified shunt-regulated power supply providing a noise-free operating point, clear tone and unbelievable dynamics with zero modulation of the noise foor.

To reduce the amount of heat generated the amplifier is biased so only the first few watts are in true class A. For peaks the amplifier switches to class B using only one leg of the output stage capable to deliver up to 150W/8ohm and 250W/4ohm.

The result is an amplifier capable of extreme power while delivering exquisite smoothness and low-level resolution.

The driver stage being isolated by the interstage transformer is not influenced in any way by the output stage operation maintaining tone, colour and resolution at all power levels and loads. Having the output stages floating around the load prompted for the use of a unique biasing technique powered by solar cells. This was the quietest galvanic isolated power we could come up with. Using opto-electrical conversion we control the bias by adjusting light intensity in the control circuit. Teres is an example of modern technology solving age-old problems allowing us to go a step beyond what was possible before.
