Good evening and happy New year! May the new year bring joy and health to you all!
For a few years now I have had an upgraded 1 usb dac which is my sole source through the 2 cd transports I use. I use its xlr outputs to the rca of my preamplifier in the way that the benchmark advises, i.e. pin 3 should remain floating. In the last months after hours of use I lose the high frequencies from my right channel or I should say better that there is a shift of the stereo image to the left, which can be fixed temporarily by playing with the back gain mode selector switch. One would say that this is the issue on the dac, but today I tried to test the rca outputs of it and not the xlr ones. I noticed that the temperature of the dac decreased noticeably, but also of my preamplifier. The sound was obviously degraded since the dac is not famous for its sound on its rca outputs. The problem also exists in the rca outputs and is even more noticeable there. I'm confused about the patch but it's playing fine... but what I'm worried about the most is the temperature thing.. should I put it in the closet and get something more modern and if so what??

It really made your preamp heat up??
Send it back to Benchmark for repair, and get a Schiit Modius in the meanwhile:

It looks like the issue was not in the dac but in one of my compression drivers of my speaker system ! Still searching though !
