Which is true. There are other QC issues too. My first unit had an error in the balanced headphone out. It would work with some plugs, not with others, so I sent it back. They replaced it with a new one, which worked better. Until the USB-C input failed, so it went back. Three times a charm? Nah, my third unit has been with me for two weeks now and yesterday, I noticed bluetooth has developed an issue. It worked fine when I got it, no background noise whatsoever. Now, I have a disturbing amount of static when I feed it over BT. I tried isolating the DL200 and switching off all mobile and other devices anywhere in the house, only to conclude that the issue is an internal DL200 one. So now, I will send this third one back too. No more SMSL products for me! PS when it works it's a nice bit of kit for the money.
