I have a pair of Infinity 7 Kappa’s i bought new in 1992 that I power with a Yamaha M70 amp I purchased new in 1983 when I was 23 years old. I had the amp recapped for $350.00 by a local shop recently, in Dallas. I had the subs refoamed a damping upgrade added to the spiders and the polydomes rebuilt by Miller Sound in Pennsylvania(they have the parts to fix the polydomes made) for a total cost of speaker repair $405.00. I swear they sound better than new. The kappas are as beautiful as the day I bought them. This system has a very warm sound and is perfect for my family room. I do have a listening room/Man Cave with Zu Omen def supremes powered by a Pass Labs XA 25 amp that is obviously superior by most any measure, but with DAC and streamer added in is an $18,000.00 investment. While I love the Zu ODS/Pass Labs system if I didn't have a spare 20k including cabling laying around I could live with my old system and be happy. I say if you like the sound of your system tune it up and save some cash.
