Tidy looking system, I was looking at the Musetec DAC thread and come to have a look. I am interested in the Tchernov USB pro cord now too.
My plan is to use low components rack/s like you have, I think it looks good, and I also like that it's kind of out of the way of interacting with the speakers too much. I've got Fideliums too, love 'em!
Good idea on the rug, have you got plans to do other room treatments?
