Well the Nucleus is now bedded in and combined with the Roon app is giving extraordinarily good results.
Together with this setup I am using a Tellurium Q Silver Diamond USB cable. This is giving a very good account of it's self with an easy and relaxed but detailed playback. I say easy, but this cable gives very good dynamics with a smooth transition. I have to say that overall I am very impressed with the sense of space and general tonal quality. Talking of space the separation of instruments is a little unnerving when you first hear it, but you soon get used to it.
