Glad to hear I'm not the only one. Mine arrived earlier this week. I don't have measuring equipment but after about 20 minutes of listening it went back in the box and was sold the next day. What a joke, I thought. It was audibly inferior to an Ifi Zen dac. The distributor told me I should have let it "burn-in". The warranty was transferred to the new owner so if he deems it's a bad unit he can deal with Vinshine/Denafrips. Maybe I'll point him to this thread to see if he can have it measured.I had a very different experience with the dac Plugged it in, it sounded OK. So I checked it on my oscilloscope (Owon XDX3062A 12bit 60Mhz) and it's a complete nightmare. I even thought that something was off with my oscilloscope, but RME dac tested perfectly as did other 3 dacs.
It appears that QC is close to non-existent.
This is with USB and 1K sine wave:

This image is with USB completely disconnected:

Needless to say, it's going back to Denafrips.
I just figured that's the way they sound. And if that's the case, it is quite mind boggling that everyone is going gaga over these things. One hell of a hype train. I also recently bought a pair of Triangle Borea BRO3's that sound absolutely awful yet every youtube reviewer said they were amazing. I'm starting to think they're all paid off. Either that or they can't hear worth shit.
May I ask, what is your measurement showing? Distortion with no input??
