Entry level speakers for tube amp?


I'm looking to purchase a pair of speakers (used or new for $400-$700) to go with an Onix SP3 amp. I've read about the Klipsch Heresy III. Any other suggestions?

Tvad,

Would it be a good match with a low powered tube amp like the Onix SP3? Are they sensitive enough?
