I own a pair of Legacy Audio Focus XD speakers Ijust got in August 2023, they have an internal 750 WPC Icepower amp, you can run them fully internally amped or bi amped. I tried them both ways, first internally amped. Then I hooked up my VAC Renaissance 70/70 amp that is 30 years old. (Fully updated in Feb 2023) When i got the VAC on the top the soundstage was much wider, deeper and layered immediately. Midrange timbre and spatial information was more real. It is still a very good amp.
