The HPA does not reproduce the sound, it plays with all its passion. Of course you can say that the violin is always controlled by man, but I believe that someone has also put a lot of heart into constructing this device. The HPA has a soul and it can be heard clearly.
Therefore, we decided to follow a different and more challenging path by designing Lab12 Hpa as a full blooded OTL tube headphone amplifier with the utmost transparent, musical and emotionally engaging heart.
And we didn’t just stop there! Hpa is not only a fully enclosed state-of-the-art headphone system which includes a high-grade USB DAC, but it’s also a fully operational high-quality preamplifier with multiple inputs, including USB that can form the heart of any high-end play back system.
The Lab12 Hpa tube preamplifier alone encompass all of our knowledge and know how and offers a performance that challenges preamplifiers costing many times the price and brings you a remarkable emotional connection to your music.
As all Lab12 products, Hpa comes with two color choices of glass blasting anodizing finish.
