If piano is a big thing for you I'd strongy recommend hearing the Soliloquy 6.2(around $2700/pr.)--makes many other speakers sound like they leave half the sound of the piano behind. They're a pretty forgiving load and sound good with lots of electronics, but I'd do something like a Placette passive pre(the one with 3 inputs at about $1400), an Odyssey Stratos amp, and maybe something like a Cambridge CD player or a Sony CD/SACD player that you can get modified later. I'd worry about the cables later--get the components(especially the speakers) right first. Best of luck.
