I had a home theater company come out to my house to give me ideas on a new surround sound system. I currently have a bose surround sound with a Yamaha 7 channel amp. They are pushing me towards the kef speaker set up. My room is about 20 x 20 x 10 foot tall ceilings. I have a 60 inch plasma above my fireplace. They want to set me up with 2 kef q900 towers for the fronts and the rest would be the kef 3005se set up with the center and satellites and the sub. I also have a 8 inch velodyne sub I will be using. The new receiver would be the onkyo 818. This set up will cost around 5000 dollars with install and set up. Is this a good set up or can I do better for the price. Any help would be appreciated.
