While both the TACT and Bel Canto are "digital amps", the newer pieces from Jeff Rowland are not. Jeff does use a very sophisticated switching power supply in his latest designs, but the amplifier section are linear designs. The advantages that can be gained from a digital amplifier (class D or PWM) are a reduction in thermal requirements, improved efficiency, and fault tolerance. This could result in a lower priced amplifier (for a given power capability) with decent performance (perhaps nearly as good as a really good linear design). The down side is the potential of RFI and excessive HF energy. Kevin Halverson
