RME ADI-2 DAC Review

RME ADI-2 DAC is one of the best sounding or audio equipment with a ton of quality features. DACs are all about the timing and noise; it converts the zeros and digital ones into the audio electrical signals. ADI-2 DAC chip is breathtaking at offering better sound resulting in quality.

There is a freshly-cut diamond to offer every single element of the song precisely with incredible realism. It supports audio files up to 768kHz, which produce genuine and natural sound. And it is an impressive performance at this price range. The audio industry is highly competitive; many companies simply upgrade to a newer version and sell it for a higher price. However, DI-2 DAC is the original, and it sounds perfect.Rme Adi 2 Dac Review

RME ADI-2 DAC Review

RME ADI-2 DAC is also a headphone amplifier with a couple of unique elements known as Extreme Power. This Dac and headphone amplifier has a super responsive display with a bright black unique look. Check out the detailed review and measurement of this updated version.


While talking about its performance, many features can be ignored, such as two different headphone outputs, automatic detection and settings, built-in parametric EQ, and a highly informative display. White LEDs contain the power button, the central rotating controller and the backlight for the switches. These all features produced an outstanding performance.

DAC Audio Measurements

Let’s start with the 1 kHz tone and measure that comes out of the XLR balanced connectors. The distortion level is at -130 dB, and the Noise level is more powerful though and controls, producing in SINAD of 115 dB. ADI-2 is a pro unit, and it creates a much higher output level than the older version. 

Although the IMD test is excellent, the output level also affects it in the dynamic range.

Headphone Amplifier Measurements

As there is no analogue input, so these measurements combine the DAC performance and the headphone amplifier. The digital volume control indicates that channel matching is outstanding, unlike analogue solutions. Bose 301 is also a good addition for music lovers.

Power measurement is 300 ohm, and the 310 milliwatts of power into 300 ohms is excellent. It intimates that it can manage high impedance headphones with ease. There is an IEM output to use on low power mode for getting lower noise.

Super Low Noise for IEM lovers

The headphone revolution brought headphones and IEMs (in-ear monitors) back into audiophiles and music lovers’ attention. Modern IEMs have a reference sound that competes with heavy over-ear headphones, presenting them with a mobile alternative and an exciting home solution. These IEMs operate on a very low voltage as these are extremely sensitive. 

Multi-Remote Support (MRC)

ADI-2 DAC comes with a remote that is readable labeled buttons and not the usual cheap add-on. The remote control presents buttons for standby volume control, on/off, bass and treble, balance, input selection, on/off loudness, mute, and EQ. 

With the help of four programmable buttons, users can access a wide range of functions and controls.
