I plan to post my spare systems in this thread.

First Spare System:

is my Living room system. There's not much to it - it's built around vintage and left-over components including my speakers bought in '75, Cartridge bought in '78, a Lenco Turntable from the 70's (though I only bought it a year ago on ebay), Electron Kinetics Eagle 2 power amp ('85). The non-vintage components are the Rega Hal preamp ('98), and the Marantz CC4300 CD changer.

The Room - is horrible acoustically. it's ~15x20 with vaulted ceilings to 18' high. My wife won't permit any radical furnishing changes, so this is why I have dedicated rooms downstairs. The Infinity's are the only speaker I've tried in this room that sound decent. They produce bass flat to 22Hz so they can fill the space nicely. I've moved these speakers around a lot in various configurations. It depends on mood. I had them on the long wall (right now they're on the short wall) for a while and they're better from an imaging perspective that way, but I finally decided I like the room better this way. The most serious listening that happens here is during morning coffee and newspaper reading.

Other spares to be posted later.
