Heed thesis Alpha Stereo Digital & Analogue Pre-Amplifier

Ex Demonstration unit. Fully boxed, fully working. Some marks on top of casework, as shown in images below.

The Thesis α (alpha) preamplifier sports two analogue and four digital inputs including S/PDIF, TOSLINK, BNC and USB. All inputs, as well as volume setting with muting function are remote-controllable via an RC handset. A twin RC-coupled output stage caters for driving long cables and connecting even two sets of power amplifiers to drive speakers in bi-amp configuration. The analogue section of the thesis α can be fed by the Thesis π twin PSU which can also supply the φ phono stage with power simultaneously.

The analogue circuit of the Thesis α is a new design from scratch, while the digital section based around our Dactil 2.1 DAC and USB 2.0 modules (by using card slots both modules are upgradeable in the future) is an enhancement of our exceptional Obelisk DA digital-to-analogue converter – „one of the finest USB DACs I have had the pleasure to audition, probably at any price”, attested the renowned journalist Malcolm Steward in Hifi-Choice and Top Audio Gear. And this worldclass performance is surpassed by the Thesis α!
