My room is not all that large, but I still use somewhat large, inefficient, totally full-range speakers in it (Revel Salon 2 speakers). In my case, I was looking to simplify my audio system, so based on word of mouth, and also what I had read about it, I brought in a Hegel H590 integrated amp for audition. Well, let me tell you something, to my surprise, and after 4 years in my audio system, the Hegel H590 is still my reference for driving my speakers to absolute incredible effect. The Hegel H590, as advertised, is extremely powerful, with a extremely high damping factor, and is extremely high current, especially for a 48.5 lb integrated. I was shocked!!! But that’s not all. The H590 sounds absolutely phenomenal as well. I do not utilize the H590’s internal DAC. The H590 actually made me not miss the large separates I use to drive the speakers with. Happy listening.
