Heed – Thesis Lambada Preamp

The Thesis Lambda is a preamplifier for the analogue-blooded fans. A remote controlled input selection and motorized analog potentiometer volume control is all that can be considered digital inside. On the analogue side, however, it is the one of the most refined preamplifiers ever built by Heed.

The amplifier circuit of the Thesis Lambda is the pure embodiment of Transcap preamplification. With the lack of any unneccessary circuitry, they made no compromises in anything. Aiming for the best possible sound quality, the Thesis λ offers an unexceptional PCB design, unique to the Thesis line amplifiers.

In a standalone mode, it is a very robust and capable device with its sturdy internal power supply. There is, however, an option to upgrade this remarkable performance to an even more astonishing level. The Thesis Pi external power supply adds more clarity, more accuracy and a great bunch of smoothness to the presentation.
