Hello. I bought a brand new
Schiit Stack (Modi 3+, Magni 3+ and Vali 2+) and I just received it, but, so far, I noticed some small “problems”:
1) I noticed that there were some
small “scratches” in all of them and always in the same place (screw hole). I contacted Schiit and they answered that:
“Those are common marks. Since they are the result of the anodizing process they will all have that mark”.

2) I noticed on it when I went to adjust the
volume knob it did not feel smooth when turning it, it felt scratchy when turning it. After some minutes, I realized that the knob was pressed against the chassis of the amp, so I took the knob off and then place the knob back with a little space between the knob and the chassis. Apparently, the problem has been solved.
My question is: Is this really normal with Schiit equipment or I've got bad ones?
*as you may have noticed by my English (hahaha), I am not from the USA, so unfortunately it would be too expensive for me to send them back to replace them.
Thanks.
