Harman Kardon AVR-430 receiver
No sub right now...
I've had this setup for about 8 months, and I love it. The sound is crisp and detailed, and very dynamic. I do want to upgrade the surrounds to the B1's, or even the R1's. In a couple of months, I will be adding an SVS PB10 to the system. Before this, I used to have a Polk RTi setup which was good, but I think the Athenas are better when it comes to detail and dynamics. I was extremely lucky when I bought these, too. The Athenas only cost me $230, and I found the HK 430 for only $375 brand new.
As for the room, it's 16 by 12. It sucks because I've got a huge glass sliding door on one side, and other opens up into the kitchen. I plan on adding some acoustic paneling on the back wall, and replacing the blinds over the glass with curtains.
I use the system mainly for movies. Probably about 80% for movies, 20% for music. My DVD player plays DVD Audio discs, but I've never taken advantage of it. When I do, though, I'm sure the percentage will change lol.
There isn't anything I don't like about the system. Especially for what I paid. My wife and I hardly go to the movies anymore. 5/5...
