Man, I tell ya...Fisher 500C, Klipsch Heresy, Technics 1200...three components built to last a lifetime. You'll probably enjoy them just as much 10 years from now as you do today. And if you don't, well, you can count on great resale. You're taking a very smart approach to sensible system building as well as synergistic component matching.
If you get the Technics, I highly recommend substituting the supplied headshell with a Sumiko model and mounting a Denon DL-160 cartridge. The DL-160 is a moving coil with output high enough to work with the Fisher's MM phono stage. Its "big" sound should go over big with any classic Klipsch fan, while its fast, detailed character will help counter the softer sound of older tube receivers.
