OTL Tube Headphone Amplifier / Preamplifier with USB DAC

This is where it all started for the Lab12. Our love for music and high-end audio was as first and foremost challenge, explored years back throughout the headphone
preamplifier. Dealing with the fragile signal and transforming it into the true high-end potent audio headphone amplifier is not the task, that everyone dares to explore.
Intimate high-end audio headphone listening offers one of the most coveted and intimate musical listening experience, yet not every headphone amplifier is THE headphone
amplifier. This is why we took a different and more challenging path and designed Lab12 Hpa as full blooded OTL tube headphone amplifier with the utmost transparent, musical
and emotionally engaging hearth. We could, but we didn’t stop there. HPA is not only fully enclosed state of the art headphone system with included pure Lab12’s highest grade DAC, but its also fully operational, high quality preamplifier with multiple inputs including USB. Hpa tube preamplifier alone encompass all of our knowledge and know how. It offers the performance, that
challenges preamplifiers few times the price and bring remarkable emotional bound. As all Lab12 products, the HPA also comes with the choice of multiple luxury paint finishes.
