I would agree that Denon is some of the best equipment out there, but, I don't agree about it being very user friendly, especially for someone that's new to HT. Their remotes tend to be a nightmare! (Get a Harmony remote, no matter what equipment you buy) Denon also uses their own language. Instead of multi-channel, they call it EXT. IN, etc...... But, if you learn quick and easy, you'd be very happy with the Denon. I also know of a couple of instances where their customer support isn't very good at all. But Denon doesn't usually have many problems. I would buy Denon, if I could afford it.
Another very good brand of receivers and amplifiers is Outlaw. See them here:
http://www.outlawaudio.com/ You can only buy Outlaw equipment online.
As for speakers, there are just so many brands that are very good, and many price ranges. There's Allison (
http://www.allisonacoustics.com), Polk, Klipsch, SVS (
http://www.svsound.com). SVS is also considered to have one of, if not the best subwoofers on the market. Especially one of these babies:

http://www.crutchfield.com, but you really need to go listen to some different brands.
Good luck with whatever you decide on.
