I just bought the Sabaj, connected to a 10th mkii sanskrit. I have a couple of akg k371s and a couple of k702s. What is your listening volume? It seems to me that I have to raise it a little too much. For example the k702 I cannot listen to them in 0db gain. There is a problem? Also in the k371, which are very sensitive headphones, I have the volume set to -35db in 0db gain.
