Finally set up a pretty good computer sound system for myself: Macbook Pro -> Audio Synthesis Passion -> Acurus A150 -> Aerial 5. Random assortment of cables: DIY Canare, Kimber 4TC, and Radio Shack. The speakers are on their own dedicated stands a few feet behind the desk. I am half-tempted by the Ayre QB-9 DAC when that comes out, but it is a bit pricey. --Andre I bet that sounds good!
