Ever had these kind of situations where you have two otherwise perfectly working to-spec items come together and not work?
And I also found out a cause of my router hanging.
It's not the number of open connections.
It's the fucking switch!!!
Basically, my mom flips a switch in her bedroom, my Zhaolu D3 DAC + Yulong T-Amp combo suddenly increases volume by twenty times (how the fuk that works beats me) and my router dies.
This flat is only 5 year old.
Fk the local electrical standards. And I still remember, when I switch on the fluorescent lamp in my old home, the USB modem dies.
So heck with all the audio anti-placebo talk. I'm gonna need a power conditioner - to get my equipment working within spec.
