Lab 12 HPA Tube Headphone Amplifier  

OTL Tube Headphone Amplifier / Preamplifier with USB DAC


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

As every LAB12 device, the full tube OTL headphone amplifier is a solid, fully handcrafted device with luxury, metal paint finishing. 

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 


Non Oversampling DAC with Tube Output

 

By combining digital and asynchronous USB inputs with classic non oversampling TDA1543 and a tube based output stage, Lab12 managed to achieve a really musical DAC that sounds like a perfect tuned High End turntable.

Every component of DAC1 is designed to provide smooth and pleasant sound - by achieving the character of pure analogue sound with non oversampling conversion by 8 matched parallel Phillips TDA1543 in sophisticated configuration and smooth output through Dual triode tube I/V stage. All components are carefully chosen after hours of listening and testing, while great attention has been paid to all the details that affect the final outcome (special audiophile power capacitors, NOS tube and more).

With its solid construction, handcrafted finishing, luxury metal painting and retro analogue V/U meters you will fall in love with it for sure.

Non Oversampling DAC with Tube Output

A DAC that sounds like vinyl

We are analog sound lovers (it is true) but nowadays digital signals flow in every modern audio system. The challenge was to achieve sound as close to the vinyl sound through a DAC. By combining digital and asynchronous USB inputs with classic non oversampling TDA1543 DAC and a tube based output stage we managed to achieve a really musical DAC that sounds like a perfect tuned High End turntable.

Every component of dac1 is designed to provide smooth and pleasant sound. We managed to approach the character of pure analogue sound through a non oversampling conversion (8 matched parallel DACs Phillips TDA1543 in a sophisticated configuration) and smooth output through Dual triode tube I/V stage. All components are carefully chosen after hours of listening and testing, while great attention has been paid to all the details that affect the final outcome (special audiophile power capacitors, tube and more).

With its solid construction, handcrafted finishing, luxury metal painting and retro analogue V/U meters, dac1 will be a pleasure not only for your ears but also for your eyes.
