The 802ds are very good speakers that will benefit greatly from a better amplifier than is in the Yamaha.  Ditto w speaker wires.   For wires and interconnects, stay away from Best Buy; that kind of stuff is their biggest mark-up item.  Best if you give us a budget of what you can spend.  Those speakers in particular are very revealing and will benefit the most from putting most of your money in a good amplifier.

you could start w/ Rotel components. Other gear that will cost more is Classe'  and Mark Levinson. Transparent cables/cords are a sonic match as well.  Best advice- go to your local dealer/retailer and listen, listen, and listen to the various electronics.
Have used Bryston amps and Transparent cabling with various B&W speakers with good results. The 4BSST might be a starting point at pre-owned pricing. They are a good value play cost/quality/warranty.
Sunfire Sig-600 will pull them at with ease. It's best amp. Face the fact: it did no depreciate since it was manufactured and even increased the used price within the past few years. The sound is to dream for so far best among the same class. Built quality is incredible and does not produce any heat. It only uses 30W of idle power so can be on 24/7.
