Gian says everything is dark. Imai actually says something similar when you buy his stuff. Because he focuses on limiting high freq distortion you may think it sounds treble is lacking but in reality only the distortion is decreased.
i think his phono is extremely dark and both Pietro and I thought so about his amp too. While Gian does like more treble than anybody I know, he is comparing it to three carts vdh Lyra and Opus. He also says at the very top of his range his products are great
