Hello,
I just got my new AT TT a few days ago and from the first time I set it up I heard a weird low hum.
My setup is the TT RCA connector to 3.5 mm jack of Kef LSX speakers with a Sommer hicon cable.
Note that I am at the very beginning of this hifi audio journey and my knowledge is limited.
What I tried so far:
- made sure the TT is set to line, not phone
- made sure the TT is set to the corect MM switch
- reseated the cartridge
- cleaned the tonearm connectors
- connected the ground from the TT to a metal desk(to check if anything changes)
- made sure the TT is really straight
- tested with another speaker
- tested with headphones Sony xm6 (no hum here)
- tested with another cable, a worse cable that I had. The hum is still present and louder on that cable
- used another wall plug
- used another power cord
Do you think I should return the TT? Or try with another power adapter? Or do you have any other ideas?
Thanks!
