Focal Chora 826 tweeter buzz


Hello, I noticed buzzing sound problem at my new Focal Chora 826 tweeters with new Marantz NR1609 receiver. I heard that when I listened piano tracks on both speakers. I tried to play piano tracks with AirPlay (16bit 44.1kHz), S/PDIF (24bit 192kHz). I tried with Pure Direct mode, but same problem. I recorded it with my phone near tweeter, here is attachment:

What else do you have connected or is it just the receiver and the speakers? Sounds like you may have a ground loop issue. I would check all connections ie the wire and the terminations. If the receiver is connected to something else you would have to look into that too. Basically.... check all connections. You could try disconnecting one item after another to see if it goes away.
