I just purchased this.
Connected Four Klipsch speakers - 2 Synergy F-20's and 2 Synergy F-30's (8ohms).
Took a bit to set up (because I didn't have the TV connected yet and the setup system is done, via the TV; although you can work around this using the display on the receiver [just a bit harder and not as many choices]. You could get around this if you have a smaller TV just for setting up. Planning on doing that this week to fine tune the set up.
Note: I didn't think I would get much of a an improvement in sound quality, though this receiver has made a huge improvement in quality and plenty of power for cranking the sound up!
So, I think it should it work with the F-28's. Though, FIRST, I would speak with someone with more insight about this receiver..
Note: The reason I haven't hooked this up to my TV yet, and the reason I bought this system, is in preparation. Price was to great to pass up AND I'm planning to upgrade 4k system, most likely a Samsung ...8000...65-70". Also will be adding a center and woofer. Putting all this in my own movie/game room.
Last note: The directions don't have a schematic for a turntable set up - disappointing because I'm a bit of a audiophile too. Still, there may be a way to make it work. If not, I just use my old amp.
