I purchased these speakers recently from a friend (original owner) and would like to have recommendations on an affordable, decent quality receiver/amplifier to drive them with so I can hear their true capabilities. I currently have a Yamaha RSV-663 and and Onkyo HT-RC160. I also need a blade/blade interconnect if anyone can help. Thanks for any advice or information you can provide would be greatly appreciated. These SDA-CRS's are the ones with the SL1000 tweeters.
