OTL Tube Headphone Amplifier / Preamplifier with USB DAC

This is where it all started for Lab12. Our love for music, for high-end audio and our exploration for many years, gave us a huge challenge when designing a headphone preamplifier that met our demand to deliver a faultless sonic signature. Dealing with the sensitive signal output and transforming it into a true high-end audio headphone amplifier is not a task that everyone would dare to explore, but for Lab12 it is one we could not resist.
High-end audio headphone listening offers one of the most coveted and intimate musical listening experiences available, yet not many headphone amplifiers on the market are able to deliver that experience adequately and to the satisfaction of true music lovers.
