OTL Tube Headphone Amplifier / Preamp with USB DAC

Most of us have experienced a situation where, on the one hand, we feel like listening to our favorite music and enjoying high-quality audiophile sound, and on the other hand, struggling not to disturb anyone around us or to not be interrupted by the activities around us. In this case, it seems that more people are considering choosing headphones to listen to their favorite music.

So keeping this in mind, we have designed a headphone amplifier, which would deliver the desired sound regardless of the quality of your headphones.

And since we're "into" tubes, what else could be better suited to bring you a full tube OTL headphone amp?

Why?

First of all, because you can use it as a great audiophile preamp to connect your system's power amp.

Second, because the HPA headphone amp offers two analog inputs and one direct USB input, so you can potentially connect almost any audio device.

In other words, you have a headphone amp and a DAC in the same device! Simply plug in your laptop and headphones and enjoy your music collection without compromising audiophile sound.

Like all LAB 12 devices, the full tube OTL headphone amp is a solid, fully handcrafted unit in a luxurious metallic paint finish.
