OTL Tube Headphone Amplifier / Preamplifier with USB DAC

Most of us have experienced a situation where on the one hand we felt like listening to our favorite music and enjoying a high-quality, audiophile sound and on the other hand we struggled not to bother anyone around us or not being disrupted by activities surrounding us. In this case, it seems that more and more are considering choosing headphones as the best way to go.

Having that in our mind, we started designing a headphone amplifier, which would offer the desired sound, regardless of the quality of your headphones. It would upgrade your sound experience no matter if you use a cheap or a high quality, expensive pair of headphones.

And since we are into tubes, what else could be most suitable from offering a full tube OTL headphone amplifier?

First of all, you can use the preamplifier output as it is, having a really audiophile preamplifier to connect your power amp of your system.

And what else can you do?

HPA offers two analog inputs and one direct usb input, so you can potentially connect almost any device….

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

As every LAB12 device, the full tube OTL headphone amplifier is a solid, fully handcrafted device with luxury, metal paint finishing. We want you to enjoy what you see as much as what you hear.

That’s why HPA have this great success and anyone who had the chance to listen to it, even for a while, just loved it…

Lab 12 DAC1 Digital to Analog converter  NLA.

NEW DAC1 Reference is now in production.


Non Oversampling DAC with Tube Output

With the ever-expanding market of digital audio, both files and online streaming services, more and more people are discovering the world of digital audio. Furthermore, in the past few years many of the most demanding music lovers and audiophiles have discovered the unique sound of non-oversampling DACs to make the most of their digital audio sources.

The biggest challenge for any DAC is the sound and not the ‘’numbers’’. Digital by default sounds very different when compared to analog and we at Lab12 have spent countless hours striving for the perfect voicing that resembles the very best qualities of analog. We couldn’t be more proud of our newest creation Dac1 reference.

In this new DAC, which is based on the same core and philosophy as the successful and multi- awarded Lab12 Dac1 Special Edition, we pushed the limits even more in all stages, such as power supply stages, digital inputs crucial paths and receivers, jitter reduction etc, in order to reach the closest approach to the original analog sound.

Dac1 reference uses eight multibit Philips DAC chips in a complex parallel configuration right after an efficient layout digital receiver stage, allied with two dual triodes tubes in output stage. Each and every part has been selected for its sonic value that brings identifiable and coherent benefits to the final sound you will hear. The result is one of a kind emotional and transparent sonic performance.

As all Lab12 products, Dac1 reference also comes with two colour choices of glass blasting anodizing finish.
