The amplifier was pleasantly surprised. Firstly, the excellent powerful sound output due to the TPA6120 current amplification. Stable, linear, without blockages and peaks, frequency response at any volume. Secondly, comfortable sound thanks to the legendary OPA2604 operational amplifier. A clear separation of channels, a slightly expanded stereo panorama is felt. At the same time, vocals (like all midrange sounds) sound close and clear without harshes and creaks. High frequencies - that's what really pleased me! All Chinese amplifiers are designed to turn your eardrums into a sieve from killing treble. Just not this amplifier. The sound is soft, there is a slight decline, about 3db at 10-20kHz. What is cool for the perception of music. General sound characteristics - veiled and pleasant A successful purchase, after which I no longer need amplifiers from SMSL and Hduoo X5 plus. Unfortunately, I could not disassemble the amplifier, the display loop was interfering. Neither on the website nor on the product page indicated an important feature. Be careful. Jack 5.25 output is connected to TPA6120 chip bypassing the 10 ohm resistors recommended in the datasheet. Which is very cool in terms of sound. But with overload, low headphone impedance or short circuit, it will immediately lead to the amplifier failure. Do not turn the volume to maximum when connected to the Jack 5.25 jack on low-impedance headphones. The minijack 3.5 is connected through 10 ohm resistors, which feels like a sound, but is safe for cheap low-impedance headphones with a distorted curved impedance throughout the frequency response The supplied "power supply" is complete bullshit! If you want a normal sound with strong bass - you need to change the PSU, at least on the PSU from laptops on 12V 3-5A of stabilized supply voltage. With this power supply, I powered up the LED strip on the backlight of the monitor, more than it, with its wild ripples and low power, is good for nothing!
