I bought this M-DAC+ from Richer Sounds in November 2023 and I was very pleased with it. Then I bought a faulty, brand new Audiolab 7000CDT transport from HiFi-Madness to go with the 6000N Play, and the CDT caused me months of hassle with Audiolab and HiFi-Madness, ending when HiFi-Madness gave me a refund. You can read more about the fault if you search avforums for 7000CDT quirk. I regret leaving HiFi-Madness positive feedback, which I can't remove now. As my sister said, "You should've gone to Richer Sounds". So now I have a Musical Fidelity CD player, which I prefer, then the helpful people at Richer Sounds provided a Chord Qutest for me to try at home. A musician friend remarked that it could not be better. To me, the M-DAC+ sounds good but the Qutest is at a higher level so I can't go back to using the Audiolab. That is why I'm selling a DAC that is as good as never used. It even has the protective film on the display. I never put batteries in the remote control.
