Gryphon antileon signature will put around 500 watts of class A power into a 2.8ohm load. Pass xa 200.5 will put 400 class A into 4 ohm or lower loads and the 160.5 320 watts class A into 4 ohm or lower loads. Heavy, hot and expensive all. Only you can decide if it's worth it. My 4 ohm speakers (88db) drop to 2.5 ohms minimum and they will play at ear crushing levels with the Gryphon.
