Since you like music, want good sound, and don't want to break the bank, start out with the 532s. Add the 534-VAC and a pair of 422s (for the surrounds) down the road. If you budget permits, and your receiver has enough power, try out the 632s (and add the 634 later on).

Congratulations! I have a similar set up (632LR's for fronts, 533VAC center, and 532LR's for surrounds, S10 for sub, 522's for presence--piano black) running on a Yamaha 2700. Have been listening to music most of the day and I am listening to a live Santana CD right now--the Aperion's sound great. I don't think I've enjoyed my CD collection this ...
