My GT went through a service center this week. The right channel was lost for an unknown reason.
Interesting thing was when you use a 4 pin XLR headphone output, then the right channel was silent but if you connect your headphones to a 6.3 mm output, then the left channel was playing through both right and left sides of your headphones, regardless the way you connect your DAC to the amp (XLR or RCA).
The verdict was "motherboard repair". I have no idea what was exactly fixed on the amplifer...)
