I was looking for a cheap dongle dac for my secondary backup rig when I saw Zeos make a few favorable comments about this dac so i started to check out what other reviewers had to say. Well, reviews were mixed, some said it ran to hot, it doesn't, (33C 92F). Another said it drained the phone battery, on my S21 it used about 10% to 12% per hour, I'm sure their are better dacs but I'm not really using it on a phone. A couple of reviewers commented that it either didn't meet power specs or that it didn't have enought power but it plays my 660s and 400i with no distortion so loud that my wife yells at me from the bedroom to turn it down when I'm listening in the living room. One thing that most people agreed on was that it sounds good and I think it does too. I listened to it for a few days and its dead silent between tracks, music is clear and transparent. I went back to my main rig a SMSL SU-8 dac and the Topping A90D and I believe this little dac is better. I can't really describe what it is but it just has the slightest more open sound. I gave the SU-8 and A90D to my wife and I'm not looking back. The ACMEE MAGIC Sound VI is fantastic.
