I would suggest that you consider Current as much as Power. I love the older Dedicated Power Amps. Plus they can be repaired if they fail. I drive old Apogee Stages with an Aragon 4004 mkII that is a dual mono - mil spec - symmetrical design from Dan D'Agostino - the designer of the early Krell amplifiers.
They are 200w into 8ohms and 400w into 4ohms and dead quiet. It weights about 60 lbs. They take total effortless control of any speakers. After 30 years I only had a single repair - A stuck startup/safety relay. You can get one on Ebay for about $1k. There is a great selection of vintage - high current - pure power amps from days past that I feel are worth the risk. Many of these older designs still cost thousands of dollars - but for a reason - not just inflation.
