Earmen ST-Amp
Earmen has recently introduced the ST-AMP. A fully balanced desktop headphone amplifier with an integrated DAC, output power up to 1.85W and a pre-amp output. Much thought has gone in the design of the amplifier, its aluminum chassis and the compact design, with the goal to hear every sound with no barrier.
Fully Balanced
The amplifier is fully balanced, so your every sound from the input will become even cleaner and better. The exact same topology is used for single ended signals, so the sound from the SE output does not stay behind the balanced output. The headphones output are powered by two TPA6120 operational amplifiers, which already have proven to be of high quality. To make the experience complete, Earmen uses a high-quality balanced ALPS potentiometer to control the volume.
Sound
ST-AMP has been designed to showcase the D/A converter. Although many DAC’s 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 and power up to 1.85W (at 32 Ohm) 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.
Low Total Harmonic Distortion is such an important factor and as such Earmen takes 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.
Connectivity
On the back panel of the device we have single ended and balanced 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.
