Thesis: beyond the absolute

Thesis amplifiers build on the expertise developed with the HV venti, combining the highest level of analogue technology with advanced digital features in a single product. The TH due is a bridgeable stereo amplifier designed for systems where versatility, power and sound quality are the priority.

• Complementary differential circuitry with current mirror.
• Cascode A Class driver with inverted complementary triplet power stages.
• Integrated 24-bit/192kHz Hi-End DA converters.
• Compatible with Audison Full DA HD technology; Hi-Res audio files listening certified.
• S/PDIF and AD Link optical digital inputs managing up to 8 digital channels on RJ-45 connector.
• Dual Mono Construction with four power supplies in Synchro-PWM configuration.
• Sensitivity control with 256-step resistive switching for 120dB resolution.
• Energy Saving, Hi-Current, Hi-AB Class and A Class presets selectable in real time.
• Digital control via integrated settings panel, DRC and PC software.
• High-quality crossover module supplied.
• Chassis extruded from solid aluminium and machined using CNC equipment.

Full DA HD

Pure digital signal transfer at up to 24-bit/96kHz resolution.

Hi-Res audio

The TH due exceeds the 40kHz bandwidth analogue requirement set by JAS (Japan Audio Society), delivering 5–70kHz (@ -3dB, 2 VRMS, 4Ω).

Digital inputs and outputs

The S/PDIF optical input allows direct connection to digital sources, with the ability to relay the digital signal to other Thesis amplifiers via the AD Link (Audison DigitalLink) system. Each amplifier features 192kHz/24-bit PCM D/A conversion through a high-quality converter.

Bias control

Four presets are selectable in real time: Energy Saving, Hi-Current, Hi-AB Class and full A Class operation.

Removable crossover

Inherited from the HV venti, the complete crossover circuit of the TH due is removable, maximising installation flexibility without compromising sound quality.

Dual Mono construction

Four Synchro-PWM power supplies deliver fast transient current response and create a true Dual Mono configuration.
