This amplifier could drive headphones over 32ohm (including 32 ohm, exclude earphone).
Does your headphone meet its best perfermance? In recent years, more and more headphone enthusiasts are willing to use high-impedance headphones. Those headphones are usually high-end headphones and have very professional performance. With those high-end headphones, amplifier is usually needed.
We spent several months to study the classic Lehmann amplifier schematic. Finally here comes this headphone amplifier.
This amplifier could drive headphones over 32ohm (including 32 ohm, exclude earphone).
As is known to all, differing with other electronic products, for headphone amplifier,tone adjusting is critically important to its performance. Best circuit designing with best components is the soul of the Lehmann amplifier. Headphone amplifer is a high precision device. Even only a little bit of noise will defect the performance obviously, making listenners bored. All is refelected in the PCB design. On the PCB board, the distance and length of signal or power traces, the signal shielding properties, and layout of all other traces is the result of careful calculation. Even a little changes will make much difference!
To make the board perform better, the PCB of this module is gold-plated. All the components on this module are carefully selected.
For 3.5mm standard headset, along this product an 3.5mm-6.35mm jack converter is included.
As mentioned before, we get it through accurate test. You could download the test file for more detail.
After all the test,it is a relief to see that this module meets all our original expactions.
Junior DIY users may not know the importance of the power supply. The +/-15V power supply is very important. This module needs pure power supply. The best supply is battery. Battery is so far the most pure power source available for users. If you need power transformer to get the +/-15V supply from 110V, ring type transformer is recommended.
As this transformer is very heavy, about 1kg, we don't plan to supply it. If you need it, we could help to customize it from a factory.
