I purchased a set of Infinity Kappa 600's almost 20 years ago with the dream of building a listening room in my house. I really know very little about quality gear but try to read a good bit to learn. Flash forward two decades and I still have my Kappas that I never bought the other components for. I would like to revive that dream and get a good amp for these speakers. Could any of you be so kind to suggest a good starting point for me on this project. I read some articles and one author said that he tested these speaker with the PS Audio Sprout100 amp. I have a Yamaha RX V-4a home theater receiver now, but I would assume this is not what I need to power these speakers. I posted in the beginners forum because I realize I know very little. I would love some good advice from you folks to get things started in the right direction for me. Thanks ahead of time. Mark
