EarMen's Super Summer Sale On Now!
EarMen ST-Amp is a Fully Balanced Desktop Headphone Amplifier with the Pre Amp option and integrated DAC. It has extraordinary sound, whether it is listened to from an integrated DAC or an external, which is great news for all those who want to have everything in one device. The amplifier is carefully made for headphones, so you can not experience unpleasant Pop and Click phenomena when turning it on or off.
Sharing the same ownership, it was natural for EarMen and Auris Audio to use the same R&D resources already proven and established within the realm of High End Audio Products.
The amplifier is fully balanced, so your every sound from the input will become even cleaner and better, but that's not all. We use the exact same topology for SE signals, so they become Balanced in a special way with almost no phase shift, additional noise or THD, which is great news because the sound from the SE output does not lag behind the sound from the Balanced output.
The headphones output are powered by two TPA6120 operational amplifiers, which have proven to be excellent in the audiophile world. To make the experience complete, we use a high-quality balanced ALPS potentiometer that contributes to the sound remaining unchanged, and the user satisfied during use.
ST-AMP affects the sound so that your DAC can be heard better. Although many DACs have excellent specifications, it is not enough for the sound to fully express itself. ST-AMP fully utilizes the maximum dynamics provided by the sound source, so you will not be deprived of any detail. In addition, it very easily controls various headphone drivers, thus improving accuracy, neutrality and transparency.
Dynamic range above >126dB will guarantee you liveliness and musicality that will allow you to never have the feeling that you are missing something. With perfectly balanced sound and incredible dynamics, you will have the feeling of being in a concert hall.
On the back panel of the device we have SE and BAL Pre-Out outputs. This option allows the user to use the ST-Amp as a DAC and preamplifier for a much more powerful system.
The sound source can be chosen according to your choice. Analog input or Digital/Integrated DAC gives you the freedom to listen to your favorite music from any source.
Low Total Harmonic Distortion is such an important feature and as such we take it very seriously. ST-Amp has Very low Total Harmonic Distortion which will allow you higher power factor, lower peak currents, and higher efficiency without distortions.
At the heart of the device itself is a noiseless linear power supply with great stability, so it can easily provide enough power even for the most demanding headphones. Apart from the special topology of the amplifier, the power supply is worthy of excellent characteristics even at full power, which is often not the case with most amplifiers, so in their specifications you can find measurements but at half power.
