Amplifiers
hARt Lab took a different approach with their amplifiers, combining the euphonic sound of tubes with the robust performance of MOSFET power in a minimalist, elegant design. By limiting the amplifier to two stages and avoiding feedback and additional circuits, these designs enable exceptional clarity and musicality.
As with all hARt Lab products, the chassis is designed with sound in mind, using multiple materials to create a component that lets you hear more of the signal and less of the chassis itself.
The result of these efforts is a component that will be at home in even the most discerning enthusiast's system.
hARt Lab offers two amplification solutions: the
dual-mono Tune Three and the Monoblock Tune Fives.
Engagement with Precision
hARt Lab's hybrid design didn't just happen overnight - 15 years of development have led us to the realization of the Tune Three and Tune Five topology. Key in the design are maintaining simplicity and purity of signal while also maintaining stability of performance over time.
