Dual Mono Power Amplifier

The Azur 651W is a two channel power amplifier, designed specifically to be partnered with a high quality digital pre-amplifier such as the Stream Magic 6.

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 as the Stream Magic 6, the 651W provides the powerhouse in a truly astonishing digital music system!

“With so much of my music in the digital domain, I rarely need a traditional analogue pre-amp any more – now I can connect my DacMagic Plus directly to the 651W and control everything from there.”
David Moore, Electronics Engineer
