By separating out power amplifier functionality, our engineers were able to give this amplifier the time and dedication that it needs to deliver the ultimate performance.
By featuring both fully balanced XLR and unbalanced RCA analogue audio inputs, the 651W is, of course, designed to work in perfect synergy with a dedicated Cambridge Audio pre-amplifier. By connecting a digital pre-amplifier such the Stream Magic 6, the 651W provides the powerhouse in a truly astonishing digital music system!
