Sony MDR-Z1R, Sennheiser HD800S, Hifiman Arya, Focal Clear, Mr. Speakers Ether Flow 1.1 with Burson Conductor 3XR
Had a great experience with the product and customer service. The Conductor 3XR is fantastic but has a slight hiss with my MDR-Z1R. I am going to buy an upgrade USB cable and see if that helps.. otherwise, I’m really happy with my purchase.
