Yeah I don't know why it needs to be an HK receiver. I would still suggest the Denon 1912 or 1613 as Smasher50 mentioned. Then go with either Kef Q500's, Wharfedale Diamond 10.2's, Focal Chorus 706V's, Ascend CMT-340's, or go straight for a pair of Wharfedale 10.4's or Focal Chorus 714V's.
Any of those speakers will dominate any HTIB or soundbar setup, and will give you a great foundation to finish building the rest of the system. Because honestly, once you hear how good it sounds you'll want to complete the system.
Also, I bought my Diamond 10.2's from musicdirect.com. You have a 30 day trial period for any speakers you buy there, so if you don't like them you can return them. My speakers came packaged nice and safe.
