I have been using a Denafrips Terminator for a few months now and to say I am pleased is an understatement.
Up until I bought the Denafrips, I was using a Metrum Octave Mk II R2R DAC and I liked it but it was the weak link in my system. It was the least expensive piece, even my speaker cables cost more, so it wasn't up to the level of the rest of my system. In my quest for a new DAC a Denafrips came up for sale and it was a few hours away and the reviews were good so I went and purchased it. It wasn't possible to audition so I went on faith.
Brought it home and hooked it up and the difference between the Metrum was night and day. To me, the music just opened up, it was good before but now I knew I could never go back. To be fair the price difference between the DAC's is at least three fold if not more. It was at this point where I finally could say I was finished the search for audio equipment. Truly I am done.
Others have described the sound of this DAC in more detail and I am not one of those guys that can do that. It either sounds right or it doesn't. I don't need hours to make that determination. The Terminator was one of those pieces that just sounded right.
For those who are interest my system is as follows: Aurender N100H music server, Denafrips Terminator, Herron Line Stage, Herron Mono Blocks, Tetra 606 speakers. Cabling and power cords by Audio Sensibility Statement series, TEO Game Changer IC's and Audio Quest Cinnamon USB. I also use Audio Points under my speakers. Argentum Acoustic Power Bar and Hubble receptacle. Focal Elear headphones and Lehmann Audio headphone amplifier.
