I am getting ready to buy the equipment for my first home theater. I remodeled the basement and have prewired it for a surround sound system. I have been looking at Yamaha Receivers. Best Buy has a series, like HTR-5280 whereas Tweeter has a series, like RXV-620. Can someone tell me how to compare these receivers made by the same company? Also, I have been looking at speakers. I like the Polk RM6600 series and have also looked at the Infinity HTS20 series. I just found the Home Theater Direct website and their Level 3 package looks good. I also read some good things about the Kenwood VR-510 on this site and also have read about the Yahama HTR-5490. I want to spend between $1,000 and $1,500 for the receiver and speakers. I will appreciate any comments or suggestions you can give me. Thanks.
