Heritage Audio Baby RAM

I was very happy to get this product, but after 3 months it started having an internal issue with the input. At some point it starts to decrease the level only on the right side of the output. I checked my interface, I have an Apollo Solo and the sound works perfect. The cables I have switched them and came to the conclusion they are fine. I use 60 Euro cables from Cordial from the interface to the input of the Baby Ram, exactly how they specify on the manual of it. TRS-TRS. Sometimes it works fine but when I restart the computer it somehow loses the power on the right side. Fun fact. If I press MONO when this happens, the sound comes perfectly from both speakers. Internally something is just bad, cheap. I hate this.
