Class D switching amplifiers are more and more common. Manufactures have made great strides in overcoming the high-frequency shortcomings found in the early models. Rotel in particular has been involved with this technology for a few years, with a significant portion of their line-up now using this.
Many manufactures of Class D amplifiers are using the well-known IcePower modules created by Bang & Olufson. These modules come in different flavors, powered modules (ASP series) of 250 500 and 1000watts and passive ones (A series) also at 250 500 and 1000watts. There are also three other series of modules supplied by B&O that exceed the scope of this review. Using these modules allow manufactures to build high-quality amplifiers without investing a ton of money and time into R&D.
