RME’s ADI-2 Pro FS is dedicated to conversion at the highest level. It therefore deserves a recommendation for sound engineering work where a central, high-quality transducer is to be used as a sound reference. It also scores convincingly with audiophile music lovers who are looking for a DA-converter of the highest quality that can effortlessly handle high-resolution audio material and DSD.
It also turns out to be a formidable, well-equipped, double headphone amplifier with reference qualities. The high level of functionality should be rated quite positively, but a puristic concept will not be addressed because – due to the integrated signal processor – you can really get going here. That’s why I’ve used the ADI-2 Pro FS to compare wired headphones for quite some time. As expected, the price for the technical and sonic full control is not cheap, but I consider it totally reasonable at about 1,599 Euros. Only the cable whip could do with a bit of aesthetic improvement.
