Out of curiosity how long did it take for the issue to happen? If I am not mistaken Schiit has 2 years warranty, You refer to this as QC problem, why did you not send it back?
Also did you open the unit and sprayed De-Oxit inside the actual pot or just tried to spray from the outside? In most cased that won't help much.
Thanks for posting Pete;
The first Magni I bought from SA was B- Stock sale , so it was as-is.
Spraying the Potentiometer with De-Oxit works for a while, but the scratchiness/noise during travel always returns. It's not bad but is irritating to hear.
I liked how the Magni sounded so I bought another one new and it worked for quite some time with no scratchiness when turned.
It has just started a week or 2 ago though so will spray it out. It is probably still under warranty so I will check.
We moved a few months ago and it has been complicated, so busy.
I recently unpacked the WHAMMY headphone amp I built that Wayne designed and it has a better potentiometer and also really sounds good.
The Magni is on the shelf now..... but I am intrigued by this Heretic that our wonderful host just road tested.
The Schmitt Audio Modi 3e DAC I recently bought is definitely an upgrade in sound over my Modi 3+.
Great to see them deliver improvements
