Thanks for all of the help and advice on matching an amp to my Cornwalls (to replace my Onkyo AV receiver) Based on the input, I decided to look for a Scott 222, or a Harmon Kardon 730 if I couldn't find the Scott. One of each showed up on E-bay- given my luck on E-bay, I bid on both, expecting to get one of the two if I was lucky.
You guessed it, got em both- $100 for the HK, and $178 for the Scott. Now I've got to convince my wife to go visit her sister while I wait for the UPS man.
Thanks again for the help.
