That 335 watts is a "bull___t" rating by Yamaha. Drive five 2 ohm speakers trying to get 335 watts out of each channel and you'll blow the receiver. It will have a stroke running five 4ohm speakers at 1/2 volume. For a pair, you should be ok with any load.
Personally, I'd consider something a little forgiving and easy to drive, maybe paradigm or B&W.
