I suspect the Plus is a new model, not sure. I think there was another amp, but I forgot to read the information on it (they all look similar).

The specials were 3 different packages. I believe they were all receiver and sub packages.

The other specials were that they were selling everything at the show at low prices so they wouldn't have to bring them back.

I agree, I thought the Hsu speakers (like Klipsch Ref bookshelf) sounded very good. I think I liked them better than most of the stuff there. I guess it's something about the horn for treble, and they don't cost as much as a car. The Totem speakers were also nice. They used a long thin speaker for the home theater stuff and just turned the speaker 90 deg for the center channel.
