I see Rotel just came out w/ 2 new digital amps, NuForce seems to be getting popular w/ great reviews, Acoustic Reality has been doing dig amps for some time now & get fabulous reviews. They are out of Denmark & they make everything in house. They all use the technology called ICEpower developed by Bang & Olefson. Do you think they will put a hurting on tubes & SS amps or merely co-exist w/ their own following. I guess time will tell. I for one am interested in them. They are extremely powerful, very small, lightweight & run no hotter than our body temp. I'll definetely give it more time to see how well they're received & wait for some more reviews. What do you think?
