hARt Lab unveiled the latest Tune Two preamplifier and Tune Three hybrid power amplifier at the Audio Video Show 2024 in Warsaw over the weekend. During the exhibition, these products were showcased alongside the OePhi Reference 3.5 speaker systems, all connected using OePhi Reference cables.
hARt Lab Tune Three is a hybrid dual-channel power amplifier that features driver tubes alongside a robust output stage utilizing MOSFET transistors. This innovative product is designed based on the Dual Mono concept, effectively merging the benefits of vacuum tubes with those of solid-state transistors. The combination of a tube-based voltage amplifier and a MOSFET transimpedance amplifier, integrated within a distinctive circuit topology and utilizing precisely matched components, delivers exceptional sound quality.
The total lack of feedback enables the attainment of perfect clarity in music reproduction. The manufacturer claims that the hARt Lab Tune Three serves as the ideal companion for the hARt Lab Tune Two preamplifier, facilitating the complete realization of the capabilities of both devices.
The sturdy chassis of the hARt Lab Tune Three amplifier is designed to effectively dampen internal vibrations, while the anti-resonance supports ensure reliable isolation from external disturbances. This amplifier delivers 165 watts per channel when operating with a nominal load impedance of 8 ohms. When the nominal load impedance is reduced to 4 ohms, the output power rises to 275 watts.
Similar to the preamplifier, there are 15 front lighting color options to choose from, along with three brightness settings or the option to completely disable the backlight. The detachable side panels allow for customization of the component's design, enabling selection based on personal taste or the surrounding decor. The finishing touch is the premium painting process, which utilizes a multi-layer application to ensure a robust and sleek surface.
The hARt Lab Tune Three stereo power amplifier is now offered for sale at a suggested retail price of 30,000 euros.
