I've owned Denafrips amps, preamps, DACs, and DDCs for over 3 years and have never had a single problem. I've also set up several systems for friends with Denafrips DACs and DDCs, and absolutely no reliability issues.
My experiences with the Iris, Hermes, and Gaia DDCs have all been flawless.....I highly recommend Denafrips DACs and DDCs. Their preamps and amps are above average, but not mid-fi or hi-fi; I've since sold mine just based on SQ
